Owner review 47: the meaning and perception of the name candidates (2026-10-27)

Status: Reference · Date: 2026-10-27 · The meaning lane of owner review 47. Dictionary senses, what a member aged 40 to 60 hears first, slang, existing apps and brands, the Latin spelling. No trademark or domain search here; those are in the screen document.

Scope: dictionary senses, what a Korean aged 40 to 60 hears first, slang/vulgar/sad/awkward senses, existing apps and brands, Latin spelling, light foreign-language check, fit to the owner's themes. No trademark or domain search was done (separate process).

Fit score (1-5) = fit to the owner's themes: tennis, group, together, sport, inclusion, cute and short. 5 = strong on most; 1 = no fit or disqualifying.

How this was researched, and what could NOT be verified

Dictionary: 표준국어대사전 (stdict) searched and every homonym opened; 우리말샘 (opendict) searched for the words stdict lacks (both "confirm" and "suggest" tabs).
Current usage: 나무위키 pages (fetched through a summarizing tool, so wording is paraphrase, not verbatim; HTTP 404 means no namu page exists), plus Google and Naver search-box autocomplete (a proxy for what Koreans actually associate with a word).
Apps: App Store KR via the iTunes search API (top 25 per term, filtered to titles containing the word) and Google Play KR search pages. Rating counts are iOS unless marked Play. An exact-name app that the store does not surface in its top results would be missed.
NOT possible: Naver Search result pages (search.naver.com is blocked in this environment), and DuckDuckGo/Bing scraping returned junk, so there is no Naver blog/cafe/news sampling. Where I rely on my own general knowledge (foreign-language meanings, famous brands), the note says so.
테며들 and 타독 could not be confirmed as words at all.

Per-name notes

치자

표준국어대사전 has four homonyms: 치자1 治者 (한 나라를 다스리는 사람 / 권력자), 치자2 梔子 (치자나무의 열매; 한의), 치자3 稚子 (열 살 전후의 어린아이 / 나이 어린 아들), 치자4 癡者 (어리석고 못난 사람). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=치자
The verb sense is not a dictionary entry: it is the 청유형 of 치다 ("그렇다 치자" = let's assume; "테니스를 치자" = let's play). Amazfit Korea used "테니스를 치자, 테니스!!" as a post title in 2019 (found in a search, not opened).
나무위키 disambiguation lists gardenia, 治者, 稚子 and a KFC menu item "치짜" (Chizza). No brand, app or company entry. https://namu.wiki/w/치자
Autocomplete (Google and Naver) is all gardenia: 치자꽃, 치자나무, 치자효능, 치자밥, 치자차, 치자가루, plus "치장" (typo neighbour). That is what a 40-60 hears first without context.
Existing: a 당근 group titled "테니스 치자" (https://www.daangn.com/kr/group-post/tfz36m479b9d/, seen as a search snippet only). App Store and Play: no app named 치자. The owner does not want a 당근 derivative; 치자 is not one, but note the orange/yellow plant color and that the one existing "테니스 치자" group lives on 당근.
Foreign: "Chija" reads CHEE-jah. Nothing bad in English or Spanish that I know of (not searched). Chinese 痴 (chī) = foolish matches the Korean 癡者 sense, but only a reader of hanja would notice.
Strength: it is the actual club verb, two short syllables, and it extends to every "hit" sport. Weakness: standalone it is a flower.

통통

표준국어대사전: 통통1 (부사: plump, "키가 작고 살이 쪄 몸이 옆으로 퍼진 모양"; swollen, "통통 불은 젖"), 통통2 (부사: sounds of knocking on a small drum, stamping feet, plucking a string, dripping drops, a small engine), 통통3 洞通 (root of 통통하다). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=통통
Namu: Lotte's 몽쉘통통 (c. 1991) was shortened to 몽쉘 in 1999 over concern that "통통" implied weight gain (namu 몽쉘, summarized by the fetch tool: https://namu.wiki/w/몽쉘). 통통이 is a clumsy-magician dragon in Pororo (https://namu.wiki/w/통통이). Autocomplete: 통통배, 통통김밥, 몽쉘통통, 허니통통, 통통코, "통통한 여자", 통통피싱.
Existing: encrypted messenger 통통 (iOS 43 ratings; Play 4.0), Tomato Group's 통통마켓/통통몰, 통통통 academy-management apps, several casual games.
Foreign (my knowledge, not searched): Mandarin 通通 tōngtōng (all), 痛痛 (tòngtòng, "ouch"), and 彤彤/童童 are common Chinese nicknames; Spanish "tonto" (fool) is visually close; Japanese トントン = tapping/pig-baby-talk.
Cute and short, but the plump reading and the messenger/shop crowd are real.

타독

Not in 표준국어대사전 or 우리말샘. Not in namu. Autocomplete returns only unrelated Japanese-name results (타도코로 etc.). I found no usage in any Korean sense.
Heard as 다독 (多讀 "read widely" or 다독다독 "pat gently") or 독 (poison, 毒). Japanese 多読 (tadoku) is "extensive reading", a coincidence.
Cut: no meaning to build a brand on.

하나둘

표준국어대사전: 하나둘 (수사/명사), "한둘"의 본말: a small number, or "one after another" ("친구들이 하나둘 자리를 뜨는 바람에", "하나둘 입주를 했다"). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=하나둘
Associations: counting cadence for exercise ("하나 둘 셋 넷"); KBS1's long-running kids' show "TV유치원 하나둘셋" (39 years as of a 2020 article, so the 40-60 generation grew up with it): https://www.ajunews.com/view/20200429085245990 and https://lady.khan.co.kr/entertainment/article/9191 (both known from search summaries only, not opened). Autocomplete: 하나둘셋, 유치원, 하나둘 팬클럽, 하나둘세민.
"하나둘 팬클럽" is a 2012 Vocaloid song (GUMI/Kagamine Rin), niche (https://namu.wiki/w/하나둘 팬클럽). No namu page for 하나둘 itself.
Existing: 하나둘 (DayPixel, Lifestyle, 0 ratings, iOS), 운동 카운터 · 하나둘 (3 ratings), Play 하나둘 가계부 (HNBCOM 4.6). 하나 also evokes Hana Bank/Hana Financial.
Foreign: "Hanadul" is read "Hana-dull" by English speakers. "Hana" = flower in Japanese (benign).
Why it scores: matches "members gather one by one" and the first-steps warmth; sports cadence for free.

으쌰으쌰 / 으쌰

우리말샘 (expert-reviewed): 으쌰으쌰 (부사) "힘을 합하여 어떤 일을 추진하고자 할 때 기운을 돋우기 위하여 잇따라 내지르는 소리"; 으쌰 (감탄사) same meaning, single shout. Neither is in 표준국어대사전 (0 results). https://opendict.korean.go.kr/search/searchResult?focus_name=query&query=으쌰으쌰&infoType=confirm
Namu: describes the shout, notes that 쌰 is missing from the old KS X 1001 syllable set (some fonts mis-render), lists 신화's song "으쌰!으쌰!" (released 1998-05-09, a summer dance track) and mentions MG새마을금고 using the word in ad copy. https://namu.wiki/w/으쌰으쌰 and https://namu.wiki/w/으쌰!으쌰!
Autocomplete: 으쌰으쌰 가사/뜻/신화/우비소년/이모티콘/노래방/일본어; 으쌰라곱창 (a grill chain). 우비소년 is a flash cartoon titled "으쌰으쌰 우비소년" (https://namu.wiki/w/우비소년). One autocomplete line pairs it with "nct wish"; I did not verify any NCT WISH song.
Existing apps: none on iOS or Play for either form.
Foreign: no known bad meaning (not searched). Latin is the weak point: "Eussya" is unreadable to English speakers; a respelling like "Ussya" would be a brand decision.
Why it scores: it is the sound of a group lifting together, familiar to every age, short in the 으쌰 form, sporty. Weak: no tennis link, spelling/typing variance, Latin.

너나들이

표준국어대사전: 너나들이 (명사) "서로 너니 나니 하고 부르며 허물없이 말을 건넴. 또는 그런 사이" (=이여). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=너나들이
No namu page. Autocomplete: 너나들이 캠핑장, 만화카페, 센터, 마을, 채, 청춘너나들이, 문화공간 너나들이.
No app on iOS or Play.
Perception: warm and equal, very inclusive; but a "pure Korean word" list item that many 40-60 know only vaguely, and it asks everyone to drop honorifics, which can clash with age-ranked tennis clubs.

넷이서

Not a dictionary headword (넷 + 이서). Autocomplete: 넷이서 할만한 게임/놀이/한마음/0촌. No app on iOS or Play (3 iOS search results, none named so). A phrase, not a name.

공친구 / 볼친구 / 통통볼

None is in 표준국어대사전 or 우리말샘. 공치다 (空치다) is: "무슨 일을 하려다가 목적을 이루지 못하고 허탕 치다" ("비가 와서 장사를 공쳤다"), which hangs over 공친구. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=공치다
Autocomplete for 공친구 and 볼친구 returns only noise (공인구, 폰친구), so no association exists; 통통볼 returns only a game-guide hit.
Apps: none named 공친구 or 볼친구 on iOS or Play; "통통볼 벽돌깨기 for Watch" (0 ratings).
볼 = cheek (볼), 볼일 (errand), bowling; 공 = ball but also 공(空) and 공(0).

덩더쿵

The standard-dictionary form is 덩더꿍 (부사: "북이나 장구 따위를 흥겹게 두드리는 소리"; "덩달아 덤비는 모양"). 덩더쿵 itself is not listed. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=덩더꿍
Autocomplete: 덩더쿵 공동육아 어린이집, 덩더쿵 어린이집, 덩더쿵 체조, 교동한과 덩더쿵, 국악방송 덩더쿵. App: 국악방송 덩더쿵 (Gugak FM, iOS 39 ratings, 2.9). No namu page for 덩더쿵.
Reads as a children's/국악 brand.

삼삼오오

표준국어대사전: 삼삼오오 三三五五 (명사): "서너 사람 또는 대여섯 사람이 떼를 지어 다니거나 무슨 일을 함. 또는 그런 모양." https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=삼삼오오
Namu: idiom from Li Bai's "채련곡"; also appeared on 장학퀴즈. No brand entries. https://namu.wiki/w/삼삼오오
Autocomplete: 삼삼오오 밴드, 커피공작소, 스터디룸, 키즈카페, 숯불갈비 (many small shops).
App: 삼삼오오콜 (3355콜) (iOS 3 ratings, 1.0; Play 3.1).
The same idiom exists in Japanese (さんさんごご) and Chinese (sānsān wǔwǔ), which is a small global plus (my knowledge). Fits "small groups gather" and doubles/foursomes, but four syllables and not cute.

폴짝

표준국어대사전: 폴짝 (부사): a small door opened/closed suddenly; a small creature jumping once lightly (청개구리). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=폴짝
Namu: 폴짝핑 is a rabbit-themed "general" Teeniping from 쥬얼스타 캐치! 티니핑, created 2026 (https://namu.wiki/w/폴짝핑). Autocomplete: 폴짝핑, 폴짝폴짝 게임, 폴짝이, 폴짝 애견놀이터.
Apps: 폴짝 - 배우·모델 오디션 공고 (iOS, 0 ratings), 폴짝폴짝 펭귄 HD (19), 폴짝홀짝 (0); Play 폴짝버드 (4.8), 폴짝냥 (2.8).
Latin "Poljjak": looks like the Croatian surname Poljak; clumsy for English readers.
The owner dislikes anything 당근-like: the rabbit/carrot picture is available to a reader.

동글이

우리말샘 has only "동글이 안경". Namu disambiguation: a KORAIL VVVF train nickname, bus-fan slang for round headlights, LG vacuum cleaner, Kiwoom Heroes mascot, a character in 프리파라, a device in 역전재판. https://namu.wiki/w/동글이
Autocomplete is dominated by 블루투스/와이파이 동글이 (USB dongle), 동글이마켓.
No app named 동글이.
English: "Donggeuri" begins with "dong", which is crude slang in US English (my knowledge).

원팀

Namu: "one team", political use "원팀론" (calling for unity in a divided party), sports "원팀맨"; homonyms 동두천 원팀 FC, 원팀캠프. https://namu.wiki/w/원팀
Autocomplete: 원팀짐, 원팀월드 피트니스, 원팀맨, 원팀커넥트, 원팀피플, 원팀 사커, 원팀풋볼아카데미, 원팀재활의학과.
Apps: 원팀-토탈HR솔루션 (OneTeam People, iOS 17 ratings, 3.8); Play 원팀(OneTeam) 푸드엔 4.1.
English "OneTeam" is a common business name (Oneteam, OneTeam360 on the US App Store).

곁

표준국어대사전: 곁 (명사) 「1」 "어떤 대상의 옆. 또는 공간적·심리적으로 가까운 데" 「2」 "가까이에서 보살펴 주거나 도와줄 만한 사람". Idiom 곁(을) 떠나다 is a euphemism for someone's death. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=곁
Namu redirects 곁 to 근방 (no brand entry). Autocomplete: 곁들이다, 곁눈질, 곁땀, 곁 혼술바, 내사랑 내곁에.
Apps: 곁 (Cadence Studio-K, Play 3.8), 곁에 (바람개비, Play 4.4; iOS 곁에 1 rating), 내 곁에 국민연금 (National Pension Service, iOS 634 ratings, 1.9 - a public brand line), Gyeot (utility, 0 ratings).
One syllable like Band; emotionally warm and inclusive. Cost: low searchability, Latin "Gyeot" is hard for English readers, and the death euphemism exists.

품

표준국어대사전 has seven entries: 품1 (garment width; chest/bosom; 엄마의 품; "조국의 품"), 품2 (effort/labor; wage labor; "품을 팔다"), 품3 (manner), 품4 品 (quality, rank), 품5, 품6 稟 (report to a superior), 품7 -品 (suffix for goods). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=품
품앗이 (mutual labor exchange, an old cooperative custom) is the strongest community resonance (https://namu.wiki/w/품앗이). Autocomplete: 품바, 품앗이, 품질, 품격, 품의서.
Apps: 품(poom) (ArtBox design shop, iOS 249 ratings, 4.7), 품(Puum) (Social Networking, 9), 품스 PUMSS (3), 품(POOM) lost-pet info (3), 품 가맹점 (3). (열품타, 48,463 ratings, is a different word.)
English "Poom" is also the Taekwondo term (poomsae); reads awkwardly.

흥

표준국어대사전: 흥4 興 "재미나 즐거움을 일어나게 하는 감정" (흥이 나다); 흥3 감탄사 (a scoffing nasal sound / delighted sound); plus 가야금 string, etc. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=흥
Namu: 흥 as the Korean cultural trait with 정 and 한; "흥!" scoff; Kakao emoticon. https://namu.wiki/w/흥
Autocomplete: 흥국생명, 흥국화재, 흥아해운, 흥신소, 흥선대원군. A search result snippet says 흥국생명 became the V-League title sponsor in September 2026 (mt.co.kr, not opened).
Apps: 흥스 (10 ratings) and 흥모임 (1) by the Siheung City Youth Foundation; 흥국생명 흥PLAY (Play 4.2).
Latin "Heung" calls up Son Heung-min for everyone, and reads as "Hung" in English.

한데

표준국어대사전: 한데1 "한곳이나 한군데" (한데 모이다); 한데2 "사방, 상하를 덮거나 가리지 아니한 곳. 곧 집채의 바깥" (outdoors; "한데 나앉다" = lose one's home; "한데서 자다"); 한데3 부사 "그런데". https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=한데
Autocomplete is dominated by the spelling question "한데 한대 / 한데요 한대요".
No namu page, no app on iOS or Play.
Perfect core meaning for "together", but the outdoors/homeless homonym and the 한데/한대 typing doubt are real. Japanese ハンデ (hande) = handicap; German "Hände" = hands (my knowledge).

넷

표준국어대사전: 넷 (수사) four. Namu redirects to the number page. https://namu.wiki/w/넷
Autocomplete: 넷플릭스, 넷마블, 워크넷, 복지넷, 오피넷. No exact-name app.
Doubles = four players and "net" is the tennis net, but the word is generic.

다정

표준국어대사전: 다정1 多情 (정이 많음), 다정2 茶亭, 다정3 茶精 (caffeine). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=다정
Namu: mostly first names (idol members, singer-songwriter 다정) and a fictional character. https://namu.wiki/w/다정
Autocomplete: 다정한 것이 살아남는다, 다정한 사람이 이긴다 (book titles), 다정이네김밥, 다정북스, 다정수학.
Apps: 다정인사 (Play 4.6), 다감 (Play 4.9), 다정해 (iOS 2), 다정한 알람 (1), 아잉 - 다정한 베트남친구 (630). Japanese 多情 (tajō) means fickle/amorous (my knowledge, not searched).

말벗

표준국어대사전: 말벗 = 말동무, "더불어 이야기할 만한 친구". https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=말벗
Autocomplete: 말벗 서비스, 말벗 봉사, 말벗 로봇, 말벗도우미, 말벗 AI, 말벗카페. Local-government and 농협 "말벗서비스" calls for elderly people living alone, and AI companion robots for them (search summary: https://newsseoul.co.kr/news/view/179589672287292, https://news.mtn.co.kr/news-detail/2023051815192520081; not opened).
Apps: 말벗 - 마음을 나누는 친구 (iOS 6 ratings), 말벗 (0), 말벗 - 언제나 곁에 있는 AI 친구 (TalkBay; Play 4.8), 라이플로 말벗·생활도우미 (Play 3.9).
Cut: it pulls toward the lonely-elder association for the 40-60 audience.

얼씨구

표준국어대사전: 얼씨구 (감탄사) 「1」 흥에 겨워 장단을 맞추며 내는 소리 「2」 "보기에 아니꼬워서 조롱할 때 내는 소리" ("얼씨구, 잘들 논다"). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=얼씨구
Namu has the 얼쑤 page (short form; a singer Wink song, a LoL pro nickname). Autocomplete: 얼씨구절씨구, 얼씨구감자탕, 얼씨구식당. No app.
The mocking sense is common in everyday speech; cut.

어기영차

표준국어대사전: 어기영차 (감탄사) "여럿이 힘을 합할 때 일제히 내는 소리" (=어기여차). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=어기영차
No namu page; autocomplete: 어기영차 뜻/서울/노래/바다로가자. No app on iOS or Play.
Same job as 으쌰 but older (tug-of-war, nets), longer and harder in Latin.

옹헤야

표준국어대사전: 옹헤야 (명사, 음악) "영남 지방에서 널리 불리는 일노래... 보리타작할 때 도리깨질하면서 부르는 노래". https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=옹헤야
No namu page; autocomplete: 옹헤야 가사/뜻/장단/악보, 옹헤야 막걸리, 옹헤야불백. No app.

테며들

Not in 표준국어대사전 or 우리말샘. No namu page (404). Naver autocomplete has the query "테며들었네 무슨 뜻" (so some people ask), Google has none.
It looks like the "X에 스며들다 -> X며들다" fan-slang pattern. The one hit I could open was an Arsenal-fan board post titled '테며들다' (fmkorea, 2021-12), whose body and comments do not explain it. So the "테" could be tennis or a football name; I could not confirm the tennis reading. Treat as unverified.
Cut: the audience will not know it, and "Temyeodeul" is unreadable.

벙개

우리말샘 (user-suggested): 벙개 = "번개모임의 준말" and a Jeju dialect form of 번개; 벙개-모임 = "번개모임을 귀엽게 부르는 말". https://opendict.korean.go.kr/search/searchResult?focus_name=query&query=벙개&infoType=suggest Not in 표준국어대사전 (standard word: 번개, which also means lightning).
Namu: 번개모임/벙개 is slang from the early-1990s PC-communication era (https://namu.wiki/w/벙개); 번개 disambiguation lists 번개모임 ("벙") but no marketplace (https://namu.wiki/w/번개(동음이의어)). It also notes the adult comic 벙개벙개.
Autocomplete: 벙개막창 (restaurant), 번개장터, 벙개벙개 완전판. "테니스 번개 모임" is an everyday Google autocomplete.
Apps: 벙개벙개 - 즉석 번개 모임·채팅 (Play, NTs, 5.0); 번개장터 (Picgo, 162,001 ratings, 4.5) dominates "번개"; meetup apps 온모임 (5), 당번 (4), 번개챗 (1), 오누프 (20).
Foreign: "Bunggae" is read like "bung" (British slang for bribe; Australian "gone bung" = broken), my knowledge.

Names to cut outright

타독: no meaning, "독" = poison, nothing to anchor.
테며들: unverifiable slang, football-fan use found, unreadable Latin.
말벗: elder-care (독거노인) association for a 40-60 audience; AI-friend apps already use it.
공친구: "공치다" = come away empty-handed.
벙개: non-standard spelling plus 번개장터/번개팅/벙개벙개 baggage, and it means "one-off", not a club.
얼씨구: sarcasm sense is in the dictionary and in daily speech.

Weak but not fatal: 볼친구, 통통볼, 동글이, 넷, 넷이서, 덩더쿵, 옹헤야, 원팀.

Context: tennis/club apps already on the Korean App Store (for orientation)

스매시 (smaxh Corp., 5,157 ratings, 4.6); 그린라이트 - 새로운 운동친구 (Enjoy Plus, 1,167, 4.5); 베이스라인 (327, 4.6); 온코트 (57, 4.4); 스포넷 (22); 행테 (10); 모스: 모두의 스포츠클럽 (0); 랠리업, 에이스, 코트메이트, 테니스맵, 라켓링크 (all under 5 ratings); 테친소 (new). Names in this category are mostly descriptive nouns, so a short non-descriptive Korean word would stand apart.

Second set

Added 2026-10-27 at the coordinator's request. Same method, same five points, same fit scale as the first set (see "How this was researched" above; the same limits apply: Naver Search pages were not reachable, namu is summarized through a fetch tool, and Naver/Google autocomplete stands in for what Koreans associate with a word). 15 entries (데굴 and 데구루루 are one row).

Summary table (second set)

Name	First sense a Korean hears	Risks	Existing apps / brands (rating counts)	Latin	Fit
칠래 ("칠래?")	The casual question "(공) 칠래?" = "wanna hit/play?"; but typed alone, search engines hear 칠레 (Chile).	Banmal (rude from an app to 50-60 year olds without 요; "칠래요?" is fine); homophone of Chile; 칠래팔래 (flippant roaming idiom) appears in Naver autocomplete; not a headword anywhere.	None on iOS or Play.	Chillae (reads "chill-ay")	3
공놀이	"Playing with a ball", a children's game ("공놀이를 하고 있었다").	Toddler/kids tone (아기 공놀이, 공놀이 장난감, 동요); generic and descriptive.	어린이 무료 축구 게임: 신나는 공놀이 (Skidos, 1 rating); "공놀이클럽" appears in autocomplete (what it is not verified). None on Play.	Gongnori	3
테린이	테니스 + 어린이: a tennis beginner. Universal in tennis circles (autocomplete: 테린이 대회, 라켓 추천, 옷, 기준, 랠리, 클럽).	Beginner label (excludes veterans; "-린이" can read as patronizing to adults); tennis-only; a same-category app already carries the exact name.	테린이 (David's Dream; iOS Sports, 0 ratings; Play 4.7, package com.tennisclubmatch.teriny, a tennis club/match app).	Terini / "Teriny" (as the app writes it)	3
공벗	Not a word. Parses as 공 (ball) + 벗 (friend), the pattern of 말벗, 글벗, 길벗.	Unfamiliar coinage; autocorrect offers 공버섯 (mushroom); literary, slightly old. 공치다 does NOT hurt it (see note).	None on iOS or Play.	Gongbeot (reads "gong-boat")	3
공친	The past/adnominal form of 공치다 = "공친 날" (a wasted day, 허탕). Also 공친왕 (Prince Gong, Qing dynasty).	Worse than 공친구: it is literally the verb form. 공치 alone is a fish (공미리).	None found.	Gongchin	1
함께해	"(Let's) do it together", the stem of 함께해요/함께해줘.	Generic slogan phrase (searchability nil); the sarcastic meme "함께해서 더러웠고 다신 만나지 말자" is a top autocomplete; spacing doubt (함께해/함께 해).	None as an exact name.	Hamkkehae	3
어서와	"Come on in, welcome", and instantly the MBC every1 show "어서와 한국은 처음이지".	Strong TV-IP association (foreigners visiting Korea); banmal imperative; songs and 어서와칼국수.	어서와! 수달 타운 (LBL, game, 63 ratings, 4.9); none on Play.	Eoseowa	3
다들	"Everyone" (다들 모여요).	Not a standalone dictionary headword; very generic; a hotel app uses the same name; "다들 그렇게 산다" (a resigned song title) and "다들 점심 먹고 와요" memes.	Daddl(다들) (Hotel Lotte, Lifestyle, iOS 0 ratings; Play 2.4).	Dadeul (reads "dad-dull")	3
데굴 / 데구루루	Something rolling; 데굴데굴 = rolling around (also in pain or laughing).	Kids/cute-game tone; 데구리 = Graveler (Pokémon); little group meaning.	데굴데굴 퍼즐 수박게임 (Lightweight, iOS 24, 4.8; Play 4.5); 애니멀 매치 3D: 데굴데굴 (33); 데굴냠 (1); Play 데굴데굴 시즌2 (4.4). None for 데구루루. Cafes named 데구르르.	Degul / Degururu	3
또르르	A small round thing rolling, or a tear/drop rolling down ("눈물이 또르르"); also the crying-meme sound.	Sad/crying association; T-ara Jiyeon song "또르르"; Latin unreadable.	또르르: 밤의 미로 산책 (iOS 7 ratings); Play 또르르 미로 (4.9).	Ttoreureu	2
방글	A soft baby smile (방글방글, "귀엽고 보드랍게 한 번 웃는 모양").	Search engines hear 방글라데시 (Bangladesh); 방글핑 (Teeniping); English "bang" slang in the Latin.	None named 방글 (a kids' reading app has it in a title).	Banggeul	3
케미	"Chemistry" between people; 우리말샘 lists 케미 as "사람들 사이의 조화나 주고받는 호흡". "복식 케미", "케미 좋다".	Crowded name space (AI chat 케미톡, 케미샷, K-pop 케미); chemical companies (롯데케미칼, SK케미칼, 한솔케미칼) and fishing 케미라이트 in autocomplete; also a romantic tint for pairs.	케미톡 (Rocketworks, iOS 92 ratings, 4.5; Play 4.1); KEMY(케미) (ARTCENTRO, iOS 16, 3.9); 케미샷 (3); 케미(Kemi) Korean speaking (2; Play 4.8).	Chemi (RR would be "kemi")	5
짝짝	Clapping sound ("박수를 짝짝 치다").	짝짝이 = mismatched pair (눈 짝짝이); 짝짝핑 (a "loneliness" Teeniping); four unrelated homonyms (tearing, tongue-smacking, sticking, clapping).	짝짝 (SEOKWON YANG, iOS Utilities, 0 ratings); Play 카드짝짝 (3.8).	Jjakjjak	3
한솥밥	"한솥밥을 먹다" = to eat from the same pot, i.e. be teammates, family, comrades.	Hansot (한솥, Korea's largest lunchbox chain) and rice restaurants (전주 한솥밥, 한솥밥쭈꾸미); sounds like a restaurant; "한솥밥 먹고 송사한다" (close people quarrel).	None as an app name (iOS, Play).	Hansotbap	3
손뼉	Hand clap; the proverb "손뼉도 부딪쳐야 소리가 난다" (it takes two).	Confused with 손뼈 (hand bone) in search; clap-to-find-phone apps own the Play results.	Play: several clap-to-find-phone apps (3.9 to 4.6); none on iOS by title.	Sonppyeok	3
끼리	Not a word: the suffix "-끼리" ("그 부류만이 서로 함께": 우리끼리). Also 끼리끼리 (cliquey) and Kiri cheese.	Exclusive by definition (opposite of inclusion); 끼리끼리 모인다 = clique; Kiri cream cheese (끼리 크림치즈) is a big grocery brand.	None standalone; many "우리끼리" apps (포트, 우리끼리 커뮤니티, 8 to 100 ratings).	Kkiri	2
동호	The stem of 동호회/동호인: "같은 취미를 가지고 함께 즐기는 사람".	Generic category word; stuffy "club" image; also a common male first name, a vegetable (쑥갓, 茼蒿), and 동호대교.	No app named 동호; category leaders: 소모임 (8,747 ratings, 4.3), 문토 (6,479, 4.6), 클루보 (29).	Dongho	3

Natural-sentence test (second set)

Name	"이번 주 토요일, ___에서 만나요"	Verb-like invitation
칠래	Weak	Strong: "이번 주 토요일, 칠래요?" (banmal without 요)
공놀이	OK	Good: "공놀이하자"
테린이	OK	No
공벗	OK	No
함께해	Odd	Strong: "함께해요"
어서와	OK	Strong: "어서와!" (welcome)
다들	Odd	Strong: "다들 모여요"
데굴 / 데구루루	OK	No
또르르, 방글, 짝짝	OK	No
케미	OK ("케미에서 만나요")	Partial: "케미 맞는 사람끼리"; works as a noun, not a verb
한솥밥	Reads as a restaurant	Good: "한솥밥 먹는 사이"
손뼉	OK	Partial: "손뼉 쳐요"
끼리	No	No
동호	OK	No
공친	Meaningless	No

Per-name notes (second set)

칠래

Not in 표준국어대사전 (0 results) or as a headword in 우리말샘; it is the colloquial 치다 + "-ㄹ래?" ("want to?"), the same verb as 치자 in the first set. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=칠래
Google autocomplete for 칠래 returns 칠레 (Chile), 칠렉스 (Chillax), 칠랜드; Naver adds 칠래팔래 (an idiom form; I could not open a source for its exact meaning, namu has no page), 칠래꽃 (a flower).
Apps: none on iOS (0 results) or Play (6 listed, no title hit).
Latin: "Chillae" reads "chill-ay", which is a friendly accident in English. Spanish speakers see Chile.
Tone: banmal without 요. For a 총무-first app serving 40 to 60 year olds, a bare "칠래?" can feel familiar to strangers. "칠래요?" works in Toss-style 해요체.

공놀이

표준국어대사전: 공놀이 (명사) "공을 가지고 노는 놀이" ("동리 조무래기들이 공놀이를 하고 있었다"). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=공놀이
Autocomplete: 공놀이클럽, 아기 공놀이, 하베브릭스 공놀이, 공놀이 동요, 공놀이 장난감, 공놀이기차. A child/toddler register.
Apps: only 어린이 무료 축구 게임: 신나는 공놀이 (Skidos, 1 rating). No namu page checked (descriptive word).
Latin "Gongnori" is readable but "gong" suggests a gong. Plain, friendly, but very descriptive and childlike for adult club members.

테린이

Not in 표준국어대사전 or 우리말샘 (checked), and namu has no page under 테린이, -린이 or 린이 (the 린이 page is a Chinese actor). So the formation (테니스 + 어린이, like 주린이 for stock beginners; 주린이 has 3 sense-hits in 우리말샘 but no exact headword) is from my own knowledge, not a source.
Usage is unmistakable in autocomplete: Naver: 테린이 대회, 라켓 추천, 옷, 기준, 랠리, 클럽, 뜻; Google: 대회 일정, 단식 대회, 라켓 추천 디시.
Existing: 테린이 on iOS (Davids Dream LLC, Sports, 0 ratings) and Play (David's Dream, 4.7, https://play.google.com/store/apps/details?id=com.tennisclubmatch.teriny, a tennis club/match app). That is a same-category app with the exact name.
Perception: cute and famous, but it labels the member a beginner, so it excludes the club veterans a 총무 recruits, and it can sound like talking down to adults. Fine as a feature name (a beginners' track), weak as the master brand.

공벗

Not in either dictionary; autocomplete only offers a correction to 공버섯. 벗 (friend) is literary but familiar to 40 to 60 year olds (표준국어대사전's 말벗 = 말동무; same -벗 pattern as 글벗, 길벗). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=말벗
Does 공치다 = 허탕 hurt it? No. 공벗 contains no 치 and does not conjugate into 공치다 or 공친. The "공" is just "ball". The only residue is the generic overlap that 공 can also mean 空 (empty) or 0, which no one reads into 공벗. The real costs are different: it is an invented word, it reads literary, it ends in a hard [공벋] and it echoes 말벗 (which carries the elder-care reading I cut in the first set; 공벗 is far less likely to trigger that).
Apps: none on iOS or Play. Latin "Gongbeot" sounds like "gong boat".

공친

공치다 (空치다): "무슨 일을 하려다가 목적을 이루지 못하고 허탕 치다" ("비가 와서 장사를 공쳤다"), so 공친 is the adnominal form ("공친 날"). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=공치다
Same trap as 공친구, but stronger because the word is the conjugated verb, not a compound. Autocomplete shows "공친 뜻", "공친다 뜻", "공치는 날", "공치는 아이"; and 공친왕 (Prince Gong, 恭親王). 공치 alone is a fish (공미리) or 工緻. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=공치
The tennis reading "공 친" (the ball that was hit) only works when spaced, and nobody will read a brand that way. Cut.

함께해

Not a headword (함께하다 is). 우리말샘 has only a user-suggested entry for a 신경준 song "지금처럼 함께해 주기를". https://opendict.korean.go.kr/search/searchResult?focus_name=query&query=함께해&infoType=suggest
Autocomplete: 함께해요, 함께해주세요, spacing queries (띄어쓰기), and "함께해서 더러웠고 다신 만나지 말자", a bitter internet meme that parodies a farewell line, first spread from a League of Legends forum video (https://namu.wiki/w/함께해서 더러웠고 다신 만나지 말자, summarized by the fetch tool). The meme sits right on the name's next-search suggestion.
Apps: none as an exact name; a cooking brand "함께해요 맛나요리" appears in autocomplete.
Warm and plainly about togetherness, but a slogan, not a name.

어서와

Not a headword. 우리말샘 lists "그대여 어서 와" (이광조, 1990) and "어서 와" (엄지, 2020).
First association is the MBC every1 show "어서와 한국은 처음이지" (pilot June 2017; a long-running hit with a Korea PD Award in 2018; namu lists season 4 as ending 2026-10-08 and season 5 slated for April 2027, summarized by the fetch tool): https://namu.wiki/w/어서와 한국은 처음이지. Other autocomplete: 어서와칼국수, 어서와자동차, 이승철 어서와, 어서와 모네.
Apps: 어서와! 수달 타운 (LBL, game, iOS 63 ratings, 4.9). None on Play.
Welcome-the-newcomer is on theme for inclusion, but the TV show owns the phrase and the imperative is casual. Latin "Eoseowa" is hard.

다들

Not in 표준국어대사전 (0 results); 우리말샘's exact hits are dialect words (다들 = 제주 방언 for 겅그레, etc.) and two song titles ("다들 그렇게 산다" by 현숙).
Autocomplete: 다들 점심 먹고 와요 (a meme), 다들 힘내 좋아, 다드림 (a different brand).
Apps: Daddl(다들) from Hotel Lotte (iOS Lifestyle, 0 ratings; Play 2.4 under Lotte Hotels & Resorts).
Latin "Dadeul" reads "dad-dull". "다들 모여요" is a natural, inclusive invitation, but the word is too common to carry a brand.

데굴 / 데구루루

표준국어대사전: 데굴 (부사) "큰 물건이 모양 없이 짧게 구르는 모양"; 데구루루 (부사) "약간 크고 단단한 물건이 단단한 바닥에서 구르는 소리 또는 그 모양" ("밤톨이 데구루루 굴러떨어진다"). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=데구루루
Autocomplete: 데굴데굴 도토리가 (a children's song), 데구리 (Graveler, Pokémon: https://namu.wiki/w/데구리), 데굴레오 (I could not confirm what it is), cafes 데구르르 (전포, 대구) and 제주 데굴데굴.
Apps: casual puzzle games named 데굴데굴 (iOS 24 to 33 ratings, 4.8; Play 4.4 to 4.5). No community app.
A ball rolling is on theme, and it is cute. No group or inclusion meaning. "Degul" reads fine, "Degu" is a rodent.

또르르

표준국어대사전: 또르르1 (paper curling), 또르르2 "작고 동그스름한 것이 가볍게 구르는 소리·모양" ("땀방울이 볼을 타고 또르르 흘러내렸다"). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=또르르
Namu has only the T-ara Jiyeon song (2010 공부의 신 OST; 2022 remake). Autocomplete: 또르륵 짤, 또르르 효과음, 또르르김밥. The crying-tear meme is my general knowledge, supported by the 땀방울/눈물 usage above.
Apps: 또르르: 밤의 미로 산책 (iOS 7 ratings); Play 또르르 미로 (4.9). Latin "Ttoreureu" is unreadable.
Cut: sad/crying overtone and no group sense.

방글

표준국어대사전: 방글 (부사) "입을 조금 벌리고 소리 없이 귀엽고 보드랍게 한 번 웃는 모양". https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=방글
Autocomplete is dominated by 방글라데시 (Bangladesh, abbreviated 방글라) and 방글핑 (a "laughter" Teeniping: https://namu.wiki/w/방글핑).
Apps: no app named 방글 on iOS; Play has a kids' reading app with 한글방글 in the title.
Smile equals welcome, which is on theme; Latin "Banggeul" invites "bang" jokes in English.

케미

우리말샘 (expert-reviewed): 케미 (←chemistry) 「명사」 "화학 반응이라는 뜻으로, 사람들 사이의 조화나 주고받는 호흡을 이르는 말"; related entries 케미 갑, 케미 깡패 ("서로 매우 잘 어울리는 한 쌍"), 케미 부부, 케미 요정. Not in 표준국어대사전. https://opendict.korean.go.kr/search/searchResult?focus_name=query&query=케미&infoType=confirm
Namu's 케미 page is mostly the chemistry abbreviation, the fishing 케미라이트, a Finnish city and a few character names; the slang has its own page (not opened). https://namu.wiki/w/케미
Autocomplete: 케미 뜻, 케미스트리, 케미컬 and chemical companies (롯데케미칼, SK케미칼, 한솔케미칼), 케미짱.
Apps: 케미톡 (Rocketworks, iOS 92 ratings, 4.5; Play 4.1, an AI character chat), KEMY(케미) (iOS 16, 3.9; Play 3.9), 케미샷 (AI group-photo chemistry camera, 3), 케미(Kemi) Korean speaking (2; Play 4.8), ORVIT (2). Many small apps, none a sports or club app.
Latin: "Chemi" reads as "chemistry" to English speakers, which is the right idea; Finnish "Kemi" is a town (my knowledge).
Why it scores: the quality a doubles partner or a club has when people click. 40 to 60 year olds know it from variety shows. Two short syllables. It is a loanword, not a native word; it can tint romantic when used for a pair.

짝짝

표준국어대사전 has four homonyms; 짝짝4 is "손뼉을 자꾸 치는 소리" ("박수를 짝짝 치다"); the others are tearing, tongue-smacking and sticking sounds. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=짝짝
Autocomplete: 짝짝이 (mismatched; 눈 짝짝이, 쌍꺼풀 짝짝이), 짝짝꿍, 짝짝핑 (a "loneliness" Teeniping, https://namu.wiki/w/짝짝핑), 롯데 짝짝이 (a baseball cheer item, from the autocomplete line only).
Apps: 짝짝 (iOS Utilities, 0 ratings); Play 카드짝짝 (3.8).
Latin "Jjakjjak" is hard to read.

한솥밥

표준국어대사전: 한솥밥 (명사) "같은 솥에서 푼 밥", used with 먹다 ("한솥밥 먹는 식구", "같은 소속사에 들어가게 되면서 그들은 한솥밥을 먹게 되었다"); proverb "한솥밥 먹고 송사한다" (even close people quarrel). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=한솥밥
Namu's 한솥 page describes 한솥도시락, called Korea's largest lunchbox chain, with a cauldron logo (the page does not mention the idiom; user-edited wiki). https://namu.wiki/w/한솥
Autocomplete: 한솥밥 메뉴, 한솥밥 푸드 서비스, 전주 한솥밥, 개구리네 한솥밥, 한솥밥쭈꾸미, 한솥밥집, 한솥밥상. Many rice restaurants.
Apps: none named 한솥밥 (iOS, Play). Latin "Hansotbap" is long.
The best idiom for "club as family" in the whole list, understood by 40 to 60 year olds. But the first thing the name suggests as a place is a rice restaurant or a Hansot outlet.

손뼉

표준국어대사전: 손뼉 (명사) "손바닥과 손가락을 합친 전체 바닥"; "손뼉도 부딪쳐야 소리가 난다"; idiom 손뼉(을) 치다 = "어떤 일에 찬성하거나 좋아하다" (example: everyone will clap and welcome you into our club). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=손뼉
Autocomplete: 손뼉치기, 손뼉을 치다, 손뼉도 마주쳐야 소리가 난다, but also 손뼈 구조 (anatomy).
Apps: on Play, five clap-to-find-your-phone apps (3.9 to 4.6) take the title hits; none on iOS.
Warm and apt (applause, partnership), pleasant to read; Latin "Sonppyeok" is awkward.

끼리

표준국어대사전: only the suffix -끼리 (접사), "그 부류만이 서로 함께" (우리끼리, 자기들끼리). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=끼리
Autocomplete: 끼리끼리 (the "birds of a feather", cliquey sense; namu points its proverb to 유유상종 without stating tone), 끼리 크림치즈 (Kiri cheese), 끼리택배 (CU), 끼리한우. Namu's 끼리끼리 page is a 2020 MBC variety show. https://namu.wiki/w/끼리끼리
Apps: many "우리끼리" apps (포트 100 ratings, 우리끼리 커뮤니티 8, 온기 4), no standalone 끼리.
Cut: a suffix that means "only among ourselves" works against inclusion, and "Kiri" is a global cheese brand.

동호

표준국어대사전 has five homonyms: 동호1 同好 ("어떤 일이나 물건을 함께 좋아함 / 같은 취미를 가지고 함께 즐기는 사람 = 동호인"), 東胡 (an ancient nomad people), 茼蒿 (쑥갓, crown daisy), 董狐 (a historian), 銅壺 (copper water clock). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=동호
Namu's 동호회 page: voluntary hobby groups, with 밴드, 카카오그룹 and 소모임 named as tools. It does not discuss age images. https://namu.wiki/w/동호회
Autocomplete: 동호인, 동호대교, 동호해변. 동호 is also a very common male given name (my knowledge).
Apps: no app named 동호. The category apps are 소모임 - 취미모임 동호회 앱 (8,747 ratings, 4.3), 문토 (6,479, 4.6), 클루보 (29). The name would sit as a plain category word beside them.

Merged top 10 across both sets (best first)

케미 (5): the doubles-partner/club "click"; short, trendy, known to all ages; many small apps already carry the word but none in sports or clubs.
으쌰으쌰 / 으쌰 (4): the sound of a group lifting together, verified in 우리말샘, no app uses it; Latin "Eussya" and the 쌰 spelling are the cost.
치자 (4): the club's actual verb ("테니스 치자"), two short syllables, reaches every hit sport; gardenia is the first hit without context.
하나둘 (4): "회원이 하나둘 모여요" plus KBS "TV유치원 하나둘셋" nostalgia; tiny apps only; Latin reads "Hana-dull".
곁 (4): one warm syllable, "곁에서 만나요" reads naturally; low searchability and a death euphemism ("곁을 떠나다").
삼삼오오 (3): the idiom for small groups of 3 to 5, no big brand in the way; four syllables, not cute.
한데 (3): the purest "together" word (한데 모이다), natural invitation; the "outdoors/homeless" homonym and the 한데/한대 spelling doubt.
칠래 (3): the same verb as 치자 as a ready-made invitation, "칠래요?"; bare 칠래 is banmal and sounds like Chile.
다들 (3): "everyone", maximally inclusive and a natural invitation; too common to be distinctive and a Lotte hotel app already holds it.
한솥밥 (3): the best "club as family" idiom for 40 to 60 year olds; sounds like a rice restaurant or a Hansot outlet.

Just outside: 너나들이, 통통, 품, 폴짝, 어서와, 공벗, 손뼉, 데굴.

New outright cuts (second set)

공친: the conjugated verb 공치다 = "come away empty" ("공친 날"); worse than 공친구. 공벗 is not hurt by this (no 치 in it).
끼리: not a word (a suffix), means "only among ourselves" (opposite of inclusion), and it is Kiri cheese.
또르르: tear-drop/crying overtone, no group sense, unreadable Latin.

Caution rather than cut: 테린이 (beginner label, and a tennis club-match app named 테린이 already exists on Play at 4.7 and on iOS). Weak: 동호 (category word, a common first name and a vegetable), 짝짝 (짝짝이 = mismatched), 공놀이 (toddler tone), 데굴 / 데구루루 (cute, no group meaning), 함께해 (slogan with a bitter meme next to it), 방글 (Bangladesh search noise), 손뼉, 어서와 (TV-show IP).

Third set: 완두 and its cousins

Scope: meaning, perception, existing apps, Latin spelling, brand-story fit, and cousin names. No trademark or domain work (separate process). Store hits below are app-store name collisions, which are a perception issue, not a legal finding.

Sourcing rules as in meaning-47.md: 표준국어대사전 and 우리말샘 opened directly; 나무위키 read through a summarizing fetch tool (paraphrase, not verbatim; 404 = no page); Google/Naver search-box autocomplete as a proxy for what Koreans associate with a word; App Store KR/US via the iTunes API and Google Play KR search pages. Not possible: Naver Search result pages (blocked here), so no Naver blog/cafe/news sampling. My own general knowledge is flagged "(my knowledge)".

Verdict: USE WITH CONDITIONS

Brand-story fit: 3.5 of 5 (a 4 only if the pod, not just the pea, becomes the visible mark). It is cute, short, instantly familiar to every Korean, and its picture (round, green, many together in one pod) maps well to a club. It is not a sports word, the tennis ball is not pea green, and a few real collisions need to be accepted or designed around.

Three biggest risks:

Same-job app already holds the name. An iOS app called 완두 (developer Dongyeop Gu, Productivity, 2 ratings) launched 2026-09-29 and is a family shared calendar ("가족의 일정을 한곳에 모아 관리하는 가족 공유 캘린더"). That is the same core job (shared schedules for a group) in the same stores. Also "Wandoo!" (Hyerin Choe, Productivity, 24 ratings in KR, 2021) and "WANDOO: Offline Hiking Maps" (AppManage) hold the Latin form.
Sound-alikes in word of mouth. 완두 is one vowel from 원두 (coffee beans, far more frequent in daily speech and ads) and from 완도 (the island/county) and 완투 (baseball complete game). Said aloud or heard on a phone call, "완두 앱" can become "원두 앱". Everyday Koreans also say 완두콩, not 완두, so the bare name reads slightly clipped or botanical.
Story and Latin baggage. The tennis ball is "optic yellow" (Koreans call it 연두색 or 노란색), not pea green; "two peas in a pod" is an English idiom, not a native Korean one; the Korean pea tales are Andersen's fussy "공주와 완두콩" and "다섯 알의 완두콩" (peas scatter); "peashooter" means weak. In Latin, "Wandu" is an Indonesian word glossed "banci" (effeminate man; derogatory register) and Sundanese "tomboy" per Indonesian Wiktionary, and "Wandoo" is crowded (Australian eucalyptus, existing apps, a Polish-looking shop in autocomplete).

Conditions: always pair the hangul with a pod/pea mark; say "완두콩" in voice-led copy; choose the Latin deliberately (section 2); treat the 완두 family-calendar app as a known neighbor.

Top 5 cousins (details in section 4): 1. 풋콩, 2. 콩콩, 3. 청포도, 4. 송이, 5. 구슬. 연두 has the best picture of all (the dictionary literally defines it as the colour of 완두콩 and Koreans call tennis balls 연두색) but is blocked in our category (below).

1. 완두 in depth

1.1 Dictionary senses

표준국어대사전 has exactly one 완두 and one 완두콩:

완두 (豌豆) 「명사」『식물』 "콩과의 두해살이 덩굴풀... 5월에 나비 모양의 흰색 또는 자색 꽃이 ... 두 개씩 피고 열매는 협과(莢果)로 식용한다 ... (Pisum sativum)". https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=완두
완두콩 (豌豆콩) 「명사」 "완두의 열매. 초여름에 열리며 식용한다." (examples: 껍질째 삶다; 밥솥에 쌀을 안치기 전에 완두콩을 까서 넣었다). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=완두콩

우리말샘 (the open dictionary, expert-reviewed and user-suggested) adds everything around it: https://opendict.korean.go.kr/search/searchResult?focus_name=query&query=완두

완두콩 「002」『책명』 a children's book by 고정욱, published 2011; 완두콩 「003」 a 2009 song by the boy band SS501 (user-suggested entry).
다섯 알의 완두콩: Andersen's fairy tale (English "Five Peas from One Pod").
완두콩집 / 완두콩 주택: "공동 소유의 토지 위에 같거나 비슷한 모양으로 나란히 지어진 여러 가구의 집" (pea-pod housing: identical houses side by side on shared land). A ready-made Korean use of "pea" for "many households together".
Compounds: 완두콩밥, 완두수프, 완두잠 (a hairpin shaped like a pea), 완두볏 (the "pea comb" of a chicken), 완두콩 단백질, pests (완두콩바구미, 완두진딧물).
No slang or vulgar sense is listed.

1.2 What a Korean aged 40 to 60 hears first

Autocomplete (Google and Naver) for 완두 and 완두콩: 완두콩, 완두콩 효능, 완두콩 요리, 완두콩밥, 완두콩빵, 완두앙금(빵), 완두순, 완두콩 심는 시기, 완두콩 공주, 코코몽 완두콩, 완두콩 크기. So the first picture is food: peas in rice (완두콩밥), as a topping in 짜장밥 and fried rice, canned peas, pea-paste bread, followed by school (Mendel) and the fairy tale. 나무위키 says children who dislike beans' fishy taste often like 완두콩밥; I found no source for the "kids pick the peas out" stereotype. The neutral-to-sweet baby image ("완두콩 크기") is also common (my knowledge: pregnancy apps compare early fetal size to a pea; autocomplete shows 완두콩 크기).

1.3 완두 vs 완두콩 in everyday speech

Everyday word: 완두콩. Plant/technical word: 완두 (Mendel textbooks say 완두; namu's Mendel page mixes both). 나무위키 notes 완두콩 is standard but sometimes called a redundant compound (겹말) because 豌豆 already means "pea-bean". https://namu.wiki/w/완두콩 and https://namu.wiki/w/완두
Bare 완두 does appear in compounds (완두앙금, 완두순, 완두빵) and in a few brands. Voice-led copy should say 완두콩.

1.4 Culture, characters, brands, apps

Mendel: seed colour (yellow vs green) and seed shape (round vs wrinkled) are two of his seven traits; green and round peas are literally in the textbook, using the word 완두. https://namu.wiki/w/멘델
공주와 완두콩 / 완두콩 공주 (Andersen, 1835): a real princess is proven by feeling one pea under twelve mattresses. Searches say "완두콩 공주". Connotation is delicacy, oversensitivity, or "공주병" (my knowledge; namu does not mention 공주병). https://namu.wiki/w/공주와 완두콩
다섯 알의 완두콩 / 완두콩 오형제 (Andersen): five peas in one pod scatter; per namu most come to a bad end. https://namu.wiki/w/완두콩
Pop culture: Plants vs. Zombies' Peashooter (완두콩 슈터); VeggieTales; SS501's 2009 song "완두콩". Autocomplete shows "코코몽 완두콩": namu's 코코몽 page has an episode title about "완두 삼형제" and friends named 두콩, 세콩, 네콩 but no character named 완두콩, so I could not confirm what that search refers to. https://namu.wiki/w/코코몽
Brands and apps found: (a) iOS 완두 (Dongyeop Gu, Productivity, 2 ratings, 5.0, released 2026-09-29): a family shared calendar with AI schedule entry. (b) iOS Wandoo! (Hyerin Choe, Productivity, 24 ratings): an online-lecture progress tracker (2021). (c) iOS and Play WANDOO: Offline Hiking Maps (AppManage; iOS 0 to 1 ratings). Other food/shop uses are in autocomplete (완두앙금빵, 완두빵). No YouTuber, mascot or well-known Korean brand named 완두 turned up in autocomplete or namu; I could not check Naver result pages.
Google Play KR: no app titled 완두, Wandu or Wandoo in the first ~20 results each.

1.5 Negative, slang, awkward senses

"Peashooter" = a weak small gun, western slang; the pea as a symbol of "small and weak" (namu).
콩알 sayings ("콩알만 하다", "간이 콩알만 해지다" = tiny, scared) attach to beans generally, not specifically to 완두 (사전 and autocomplete).
Prison slang "콩밥을 먹다" exists; namu says the beans in prison rice were soy or kidney beans, not peas, so 완두 is mostly spared. https://namu.wiki/w/콩밥
Raw-pea digestion warnings (namu) and pea-shoot toxin notes are irrelevant to a name.
The "pea princess" reading (fussy, delicate) is the one social stereotype that can attach.

1.6 Sound-alikes: does it matter?

Word	Meaning	Closeness	Matters?
원두	coffee beans (원두1); also 園頭 melons/cucumbers (원두3, as in 원두막), 原頭, 圓頭	One vowel (ㅘ vs ㅝ)	Yes. Highest-frequency neighbor (autocomplete: 원두커피, 원두 그라인더). In noise or on a phone, "완두" is easily heard as "원두".
완도	완도읍 and 완도 island/county in Jeonnam (a ferry port to Jeju; abalone, kelp, laver farming)	One vowel at the end	Moderate. Strong local-place reading: "완도 날씨", "완도 제주 배편". Latin "Wando" is the island's spelling.
완투	完投, a pitcher finishing a whole game	One consonant	Low for the general public, but baseball fans in the 40-60 range will hear it.
반두	a hand fishing net (반두1); 班頭; 飯頭	Initial consonant	Low.

All dictionary checks: https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=원두 (and 완도, 완투, 반두 likewise).

2. Latin spelling

Spelling	How English speakers say it	Existing meanings found	Verdict
Wandu	"WAHN-doo" or "WAN-doo" (also "wan-DOO"); a few will see "wand" + "u"	Matches Revised Romanization of 완두. Pinyin "Wandu" is 丸都 (Wándū), the Goguryeo fortress (Hwando mountain city, UNESCO) in Ji'an, China (en.wikipedia "Wandu"). Taita (Kenya) "wandu" = plural of "person" (en.wiktionary). Indonesian Wiktionary glosses "wandu" as "banci" (effeminate man/transgender, usually pejorative) and, in Sundanese, "tomboy"; its entry does not mark it derogatory, and I could not open a Javanese source. German "Wand-" = wall (autocomplete: "wanduhr" wall clock). No Spanish, Swahili, Arabic or Hindi meaning found (not exhaustively searched).	Closest to the sound and to 완두; the Indonesian sense is the only real hazard and it is regional.
Wandoo	"WAHN-doo" (Australian "WON-doo", my knowledge); "doo" is unmistakable	Eucalyptus wandoo and five other eucalypts called wandoo (Western Australia; en.wikipedia "Wandoo"); autocomplete: "wandoo na raty", "wandoo pl" (looks like a Polish installment shop, autocomplete only); apps: Wandoo! (Productivity, KR 24 ratings) and WANDOO Offline Hiking (Navigation).	Clearer pronunciation and cuter, but the most occupied; hiking-map and productivity apps already use it.
Wan-du	Two syllables, but the hyphen reads as a mechanical split	Same as Wandu	Looks dated; the hyphen breaks handles and URLs in practice. Not recommended.
Wandou (pinyin for 豌豆)	"wan-DOW" / "WAHN-doh"	Exactly Chinese for pea (wāndòu)	Plays well in Chinese markets only; English readers will mispronounce.

Other points:

"Wan" as "wan": yes, an English reader can parse Wan- as "wan" (pale, sickly). It is a mild background effect; "Wandoo" and "Wandu" are both exposed. In Japanese, ワン (wan) is "one" and the dog's bark, so "Wan-du" will sound like "one-do/one-two" to a Japanese ear, which is friendly.
CJK shared root: 豌豆 reads wāndòu in Chinese and えんどう (endō) in Japanese, so the picture ("pea") travels, a plus the owner flagged. The Latin "Wandu" is close enough to wāndòu that Chinese speakers will hear "pea" (my knowledge).
Spanish, Arabic, Hindi, Swahili: no meaning found for Wandu or Wandoo; not exhaustively searched.
Recommendation: if hangul is primary, "Wandu" (RR) is cleaner and is not occupied by an app title in either store; check the Indonesian reading before any Indonesian-market plan. "Wandoo" reads better but is already used by a productivity and a hiking app.

Store check for the Latin forms (iOS KR/US, Play KR, name hits only): Wandu none; Wandoo two apps (above); Wando: Sodexo's "Wando App", a Wando high-school athletics app (US), a game. No results titled "Wandou" or "Yondu".

3. Brand story for a tennis-club app

Candid score: 3.5 of 5 (picture 4; tennis-specific fit 2; Korean familiarity 5; cute and short 5; collisions drag it down).

What carries:

Round like the ball; "알알이" many together in one pod (깍지/꼬투리) = members of one club. The pod word is 깍지: 깍지1 is the husk of a bean pod (the 표준국어대사전 example is literally 완두 꼬투리 and 빈 깍지) and 깍지2 is two hands interlocked (손깍지, "깍지를 끼다"), a quiet double image for partners.
우리말샘's 완두콩집 (identical houses side by side on shared land) is a Korean precedent for "peas = many households together".
Mendel's textbook peas are round or wrinkled, yellow or green; most Koreans met "둥근 완두" in school science (my knowledge).
"Two peas in a pod" for a doubles pair works as a picture, even though the idiom is English (Korean uses 붕어빵 or 판박이 for "alike"; for "close as family" the idiom is 한솥밥).
2 syllables, easy to say, never offensive, loved by small children and grandparents.

What does not:

Tennis balls are optic yellow (the ITF allows only yellow or white; en.wikipedia "Tennis ball"). Korean autocomplete shows people debating "테니스공 연두색 노란색". A pea is deeper green; the ball is closer to 연두.
Nothing in 완두 says sport or play, unlike 치자 or 공놀이. The tennis link is only the round shape.
A real pea pod holds roughly 4 to 10 peas, so "two in a pod" is about pairs, not clubs. Andersen's five-pea tale ends with the peas scattered.

Strongest one-line story:

Korean: "한 깍지 속 완두콩처럼, 우리는 한 코트에 모여요."
English: "Peas in a pod, players on a court."

4. Cousins with the same picture

Score = how well it carries round, green, together and cute, after baggage (1-5). Dictionary: stdict/opendict; autocomplete: Google/Naver; apps: iOS KR counts unless marked.

Name	Sense and picture	Baggage and collisions	Latin	Score
연두	연두2 軟豆: "완두콩의 빛깔과 같이 연한 초록색" (the dictionary defines the colour as that of a pea). Yellow-green, which is also the tennis ball's colour. 2 syllables.	Blocked in our category: a tennis tournament management and entry app named 연두 (DAEGAM/연두스포츠; iOS 3 ratings, released 2026-10-01; Play 3.5, net.ydtennis.yeondoo) and a "연두 테니스 아카데미" in autocomplete. Also Sempio's 연두 seasoning (famous "연두해요" ads, 2015) whose romanization "Yondu" equals the Marvel character; 연두부 (soft tofu); 연두1 年頭 ("연두 기자회견"); 연두색 번호판.	Yeondu / Yondu	2 (picture 5, but taken)
녹두	Mung bean: small, round, green seed.	녹두장군 (Jeon Bong-jun, nicknamed for his small stature), 녹두전, the Seoul street 녹두로/녹두거리; earthy and historical; no app found.	Nokdu	2
풋콩	"깍지 속에 들어 있어 아직 덜 익은 콩": green beans in the pod, the literal "peas in a pod" picture. 3 syllables.	"풋-" means unripe and young ("풋내기" is a mild put-down, "풋사랑"); Google autocomplete: "풋콩 완두콩 차이" (people confuse them); the generic 콩밥 (prison) idiom attaches to beans; no app found.	Putkong	3
청포도	Green grapes, a round green cluster (together). Dictionary: unripe green grapes; a grape variety.	이육사's 1939 poem "청포도" (famous; not verified as a textbook text), candy/ade/sherbet flavour, 샤인머스캣 confusion; 4 syllables in Latin; no app found.	Cheongpodo	3

콩알	A single bean; tiny and cute.	"콩알만 하다" belittles; "간이 콩알만 해지다" = scared; 속어 for a bullet; 콩알탄 (toy firecracker); iOS 콩알 (Heetae Kim, Utilities, 3 ratings, 2.3).	Kongal	2
강낭콩	The class-project bean ("강낭콩 키우기", nostalgic).	Mottled, not green; the dictionary note on 강남콩/강낭콩 invites 강남 jokes; one of the beans in prison rice; 3 syllables, long Latin.	Gangnangkong	2
청귤	Green unripe mandarin (Jeju), round and green, 2 syllables.	Jeju-specific, 청귤청/에이드; no group sense; one more produce name beside 당근.	Cheonggyul	3
개구리	Green and hopping, cute.	개구리 소년 사건 (1991 Daegu, five boys; remains found in 2002; my knowledge, autocomplete's first line is "개구리소년"); 청개구리 (contrary child); Pepe the Frog; games only.	Gaeguri	2

Five more of my own (Korean, 2-3 syllables, cute)

Name	Sense and picture	Baggage	Latin	Score
콩콩	Light hops and a heart thumping ("가슴이 콩콩 뛰다"); a doubled 콩 = two beans; fits footwork.	콩콩귀신 (hopping ghost), 스카이콩콩 (pogo stick), a dog's bark; kids' content 콩콩팜팜; apps: 콩콩던전 (game, 456 ratings, 4.5), 콩콩 (0 to 16 ratings).	Kongkong	3
구슬	Marble or bead: round, glassy; childhood marbles; the proverb "구슬이 서 말이라도 꿰어야 보배" (beads only become treasure when strung together).	Not green; 구슬2 is the Arabic ghusl (ritual bathing, irrelevant in Korea); game apps (구슬세계 377 ratings), 구슬아이스크림.	Guseul	3
올망졸망	"귀엽고 엇비슷한 아이들이 많이 있는 모양" / small bright things gathered: the "peas in a pod" feeling as one word.	Four syllables; a few small shops use it; the clipped 올망 is not a word.	Olmangjolmang	3
알콩	From 알콩달콩 ("아기자기하고 사이좋게 사는 모양"); 알 + 콩 puns on grain and bean.	알콩 alone is not a headword; leans to couples and families; many small businesses use 알콩달콩.	Algong	3
방울	A bead of liquid, a jingle bell; round, cute, 2 syllables.	방울토마토 dominates; 방울뱀 (rattlesnake); a dog name; kids' 방울핑.	Bangul	2

Top 5 cousins (best first)

풋콩 (3): the closest literal cousin (green bean in a pod), cute, 3 syllables, no app found; watch the 풋- "unripe" tone.
콩콩 (3): carries "two beans", bouncing and heartbeat; the least baggage in sport; generic kids' use.
청포도 (3): round green cluster, warm poem memory for 40-60; sweet-shop tone, long Latin.
송이 (3): "many on one stem", short and soft; the mushroom takes the search.
구슬 (3): round and shiny with the best "string them together" proverb; not green.

Best picture, blocked: 연두. Worth noting that the dictionary itself ties 연두 to 완두콩's colour; the tennis-tournament app (and Sempio's seasoning) block it.

Fourth set: soft openings, pods and symbols

Owner criterion added today: the name should open with a soft sound (like 완두) so it projects acceptance; English words are allowed. 완두 itself is blocked (a 완두 family-calendar app and a pending 완두콩 mark). No trademark or domain work here (separate process). Store hits are name collisions in the app stores, a perception issue, not a legal finding.

Same sourcing and limits as meaning-47.md and meaning-wandu.md: 표준국어대사전 and 우리말샘 opened directly; 나무위키 through a summarizing fetch tool (paraphrase; 404 = no page); Google and Naver autocomplete as a proxy for what Koreans associate with a word; App Store (KR and US via the iTunes API) and Google Play KR search pages. Naver Search result pages are unreachable. My own knowledge is flagged "(my knowledge)".

The six points per name: (1) dictionary senses, (2) what a Korean aged 40 to 60 hears first and any slang/vulgar/sad/awkward sense, (3) existing apps and brands, (4) Latin spelling plus a light foreign-language check, (5) fit 1-5 to the owner's themes (tennis, group, together, sport, inclusion, cute and short), (6) does it open softly and read as accepting or welcoming?

"Opens softly" here means the first sound is a vowel or a glide (아, 어, 우, 으, 워, 와) or a plain breath (ㅎ), with no burst of a stop (ㅂ, ㄱ, ㄷ) or tense consonant at the start. 완두 itself opens with the glide 와.

Summary table

Name	First sense a Korean hears	Risks	Existing apps / brands (rating counts)	Latin	Fit	Opens softly? Reads accepting?
한깍지	Not a word. Parses as 한 (one, same: 한식구, 한솥밥) + 깍지 (pod or interlocked fingers): "one pod".	Coined; 깍지 alone mostly reads as clasped hands (깍지 끼다) or the pest 깍지벌레; pronounced [한깍찌], crunchy; no search footprint.	None (iOS, Play).	Hankkakji	3	Partly: "han" is soft, but the tense 깍지 is crisp. Accepting by meaning (한 = same pod).
손깍지	Interlocked fingers, the romantic hand-hold ("손깍지 스킨십, 심리, 키스").	Couple-coded; intimate for a club of strangers; tense 깍.	None (iOS, Play).	Sonkkakji	3	Partly (s). Warm but intimate.
알알이	"Each grain, one by one" (알알이 영글다, 알알이 맺힌 포도), a harvest word. Pronounced [아라리].	An adverb, not a noun; relatives 알알하다 (stinging) and the small shops 알알이푸드/마켓/하우스/쏙; spelled 알알이 but said "아라리", so typing and hearing differ.	None named 알알이 (iOS, Play). Autocomplete: 알알이쏙 (Daiso item), 알알이하우스, 알알이 계란.	Arari (Revised Romanization of the sound)	4	Yes: opens on a bare 아. Reads accepting: every single one counts.
알콩	Half of 알콩달콩 ("아기자기하고 사이좋게 사는 모양"); 알 (grain) + 콩 (bean).	Not a headword; couple or family tint; autocorrects to 알코올 (alcohol); many businesses use 알콩달콩.	알콩 - 커플 퀴즈 (iOS Lifestyle, 1 rating); 로컬마켓 알콩 (0); Play 알콩Viewer, 알콩로직 (Drake.Jang, 4.0 to 4.8).	Algong	4	Yes (아). Accepting: friendly closeness, but domestic.
얼싸	얼싸안다 (hug each other, "서로 얼싸안고 기뻐했다"). The headword 얼싸 is the folk cheer "얼싸, 좋네".	Dictionary sense 2 of 얼싸 is sarcasm ("조롱할 때 내는 소리", = 얼씨구), the same trap I cut earlier.	None (iOS, Play).	Eolssa	2	Yes (어). Accepting via 얼싸안다 only.
아름	두 팔을 둥글게 모아서 만든 둘레: "한 아름" (an armful); but ears hear 아름다운 (beautiful) and the girl's name 아름.	Generic and crowded; 아름다운가게 (charity thrift-shop chain) dominates autocomplete; common given name.	24 of 24 iOS KR results contain it (AREUM 퍼스널 컬러 8 ratings, 아름북스 4, 오늘의 아름 1); Play 아름동행 (Jeju Senior Club 4.8), 아름북스 (4.5).	Areum	4	Yes (아). Accepting: an embrace of two round arms.
울타리	Fence; "한 울타리" = one household or community; protective home.	Boundary as well (울타리 밖); 한울타리 is the stock name of daycares and nursing homes; proverb about a broken fence inviting the neighbour's dog.	울타리 (iOS Lifestyle, 1 rating); 울타리몰 (8); 울타리 학원 셔틀 (0); Play 울타리몰 (4.1).	Ultari	3	Yes (우). Accepting but fenced.
아무나	"Anyone, whoever."	Hits: "사랑은 아무나 하나" (hit-song title), "아무나 따라가지 않아요" (child-safety, don't follow strangers), "아무나하고 자는..." (sexual), "아무나 Solo 결합" (dating). Also "not just anybody can" (elitist) and "treating people as interchangeable".	iOS none; Play 아무나스티커 only.	Amuna	1	Yes (아). Reads careless or risqué rather than welcoming.
응원	Cheering and support: "선수들이 힘을 낼 수 있도록 도와주는 일", also "곁에서 성원함". 응원봉, 응원가.	Everyday word; the stores are full of LED-scroller and fan-lightstick apps; Latin is awkward.	아이돌 응원봉 (528 ratings), 모두의응원 LED (300), LED 전광판 apps; Play 응원도감 프로야구 (5.0), 정동원 응원봉.	Eungwon	3	Yes (으). Strongly accepting and a sports word.
Amity / 아미티	English "friendship, friendliness, peaceful relations" (formal, literary; from Latin amicus). For Koreans, an unknown sound that suggests 아미 (BTS ARMY).	Amityville Horror, Amity Island (Jaws), a Divergent faction, Amity University (India, large), AEON-Amity (Japan); 아미 티셔츠 in autocomplete.	Amity (Copiri, US Lifestyle, 75 ratings, 3.9); Amity: Sibling Harmony (4); Amity University (3); about ten more small ones. None named 아미티 in KR.	Amity ("AM-ih-tee")	3	Yes (A). Accepting by meaning, but the word is rare and does not say Korean or tennis.
Oval / 오벌	English: an egg-shaped ellipse; in Australian English a sports ground. For Koreans: eyewear/jewelry shapes ("오벌 선글라스, 접시").	Oval Office (power), The Oval (cricket), Ovaltine; the Korean sound is one vowel from 오발 (misfire: 오발탄, 오발 사고). Egg-shaped, not round; no human warmth.	OVAL Key / Home (ImGATE, KR 8 to 9 ratings), President & Oval Office News (463), Oval - Campus Life (2).	Oval ("OH-vul")	2	Yes (O). Neutral geometry, not accepting.
해달	Sea otter; sleeps holding paws so they don't drift apart (Korean query: "해달 손 잡고 자는 이유"); Chiikawa's Rakko.	Confused with 수달 ("해달 수달 차이"); two couple/date apps use the name; may also be read as "해와 달" (sun and moon; my reading, not sourced); no sports link.	해달 Haedal - 데이트 지도, 커플 기록 (iOS, 3 ratings); 해달 프리다이빙 (3); Play 해달 소리, 떠있는 해달, 아기해달! (4.9). 해달스파, 해달네일 as shops.	Haedal	4	Mostly: "hae" is breathy and soft. Accepting: the hand-holding image.
병아리	Chick; "병아리 기자/배우" (a beginner); chickpea (병아리콩) takes the search.	Beginner label can condescend to adults; fails the soft-opening test (ㅂ); a pop-culture nickname 삐약이 (table-tennis star 신유빈).	병아리 한국어 스티커 (193 ratings), 병아리 키우기 games (174), 병아리 방탈출 (45).	Byeongari	3	No: opens on a ㅂ. Cute and welcoming to newcomers, a bit diminutive.
원앙	Mandarin duck; "금실이 좋은 부부" (devoted married couple), 원앙금침 (wedding bedding).	Marriage-coded; a couples messenger named 원앙 already exists; namu notes the "fidelity" image is not accurate and the wedding bird was really the goose.	원앙 - 커플 메신저 (Zena Korea; iOS 2 ratings, Play 4.7); 종이 혼례복 3 원앙빚 (game, 55).	Wonang	3	Yes (워, the same glide as 완). Accepting for a pair, not for a group.

Per-name notes

한깍지

Not in 표준국어대사전 (0 results). Autocomplete returns nothing for 한깍지; Naver redirects to 손깍지 queries. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=한깍지
The pattern 한 + noun is genuine Korean for "same, one": 한솥밥 is a headword ("같은 솥에서 푼 밥"); 한식구 is not a headword; 한 울타리 appears in autocomplete as a stock name of daycares and nursing homes (한울타리어린이집, 한울타리요양원).
깍지1 = "콩 따위의 꼬투리에서 알맹이를 까 낸 껍질" (the example is 완두 꼬투리); 깍지2 = "열 손가락을 서로 엇갈리게 바짝 맞추어 잡은 상태" and the archery thumb ring; idiom 깍지(를) 끼다. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=깍지 Autocomplete for 깍지: 깍지벌레 (scale insects) first, then 손깍지, 깍지콩, 국궁 깍지.
Apps: none on iOS or Play. Latin "Hankkakji" is awkward for English readers.
6: the 한 prefix is the right "one, whole, together" signal, but most Koreans parse 깍지 as clasped fingers, not a pod, so the "peas in a pod" image is lost; the mouthfeel is crunchy ([한깍찌]).

손깍지

표준국어대사전: 손깍지 (명사) "열 손가락을 서로 엇갈리게 바짝 맞추어 잡은 상태" (= 깍지); one example has soldiers making a clasped-hand foothold. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=손깍지
Autocomplete: 손깍지 심리, 의미, 방향, 스킨십, 키스, 영어로. A couples gesture first and a prayer/stirrup second.
Apps: none. Latin "Sonkkakji" starts with "Son" (the footballer's surname, or "son").
6: warm but intimate; for strangers in a club the couple register may feel too close.

알알이

표준국어대사전: 알알이 (부사) "한 알 한 알마다" (알알이 잘 여문 벼; 감자가 알알이 실하다); pronounced [아라리]; spelled 알알이 under the 맞춤법 rule. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=알알이 The related 알알하다 means stinging or tipsy and is a different headword (알알하다1: 혀끝이 아리고 쏘는 느낌).
Pronounced [아라리], it sounds like the 아라리 of 정선아라리 (the Arirang tradition), a folk-song association I rely on my own knowledge for (not searched).
Autocomplete: 알알이푸드, 알알이마켓, 알알이쏙 (Daiso), 알알이하우스, 알알이 계란, 알알이 카톡테마. No app named 알알이 on iOS or Play.
Latin: the Revised Romanization of the sound is "Arari", easy to read and symmetrical ("ah-RAH-ree"); "Arari" is also a Brazilian town (my knowledge). If the user types the spelling 알알이 and says "아라리", search and voice will diverge.
6: the softest possible opening, and the meaning is the most accepting here: each grain counts, no one is left out. Cute, round (a grain or bead), short.

알콩

Not a headword; 알콩달콩 is: "아기자기하고 사이좋게 사는 모양" (알콩달콩 사랑하는 이야기; 가족들과 알콩달콩 살아가다). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=알콩달콩
Autocomplete for 알콩 returns 알코올 (alcohol) and 알콩달콩 (preschools, 한정식, 선물가게, 사진관, 콩국수). A short typing or voice-search hazard.
Apps: 알콩 - 커플 퀴즈 (iOS Lifestyle, 1 rating, 5.0), 로컬마켓 알콩 (0); Play 알콩Viewer and 알콩로직 (Drake.Jang; 4.8 and 4.0).
Latin "Algong" reads "AL-gong".
6: opens on 아; the meaning is harmonious closeness, a little couple/family-coded.

얼싸

표준국어대사전: 얼싸 (감탄사) 「1」 "흥겨울 때 내는 소리" (얼싸, 좋네) 「2」 "보기에 아니꼬워서 조롱할 때 내는 소리 (= 얼씨구)". 얼싸안다 (동사) "두 팔을 벌리어 껴안다" ("우리는 서로 얼싸안고 기뻐했다"). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=얼싸
Autocomplete: 얼싸안다 first, then 얼싸좋다 and a 김일병 phrase. No app on iOS or Play.
Latin "Eolssa" is hard.
6: the verb 얼싸안다 is the most welcoming act in the list, but the headword 얼싸 shares the sarcasm sense of 얼씨구, which I cut earlier. Use 얼싸안다 in copy, not as the name.

아름

표준국어대사전: 아름1 「명사」 "두 팔을 둥글게 모아서 만든 둘레" and a unit (꽃을 한 아름 사 오다; 두 아름 되는 느티나무); 아름2 the root of 아름거리다 (blurry); 아름3 → 아람 (ripe nuts). 아름답다 is a separate headword. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=아름
나무위키: 아름 as an archaic "I/self", a nickname for the few women in engineering (from a KT ad), a common girl's name, 아름초/중/고 in Sejong City, 아름핑 (a Teeniping). https://namu.wiki/w/아름 Autocomplete: 아름다운가게 first.
Apps: all 24 iOS results contain 아름 in name or seller (mostly 아름다운). AREUM 아름 퍼스널 컬러 (8 ratings, 4.5), 아름북스 (4), 오늘의 아름 (1); Play 아름동행 (Jeju Senior Club, 4.8), 아름다원.
Latin "Areum" ("ah-ROOM" or "a-REEM"); "arum" is a lily genus (my knowledge).
6: soft vowel opening; the circle of two arms is both the "round" and the "accepting" image in one syllable pair. Weak point: it will read as a person's name.

울타리

표준국어대사전: 울타리 (명사) "풀이나 나무 따위를 얽거나 엮어서 담 대신에 경계를 지어 막는 물건"; idiom 울타리를 벗어나다 (leave a narrow limited life); proverb "울타리가 허니까 이웃집 개가 드나든다" (a weakness invites contempt). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=울타리
Autocomplete: 울타리 펜스, 울타리몰, 울타리 만들기, and the 한울타리 family (어린이집, 요양원, 여행 and regional names).
Apps: 울타리 (iOS, 1 rating), 울타리몰 (a Korean grocery shop, 8 ratings), 울타리 - 학원 안심 셔틀 (0), a hospice charity app, Play 울타리몰 (4.1).
Latin "Ultari" ("ul-TAH-ree"), close to "ultra".
6: soft vowel opening; protective and homely, but the image is a fence, which means boundary as well as shelter.

아무나

Not a headword. Autocomplete: "사랑은 아무나 하나" (the song title), "아무나 따라가지 않아요" (child safety), "아무나하고 자는 네가 좋아", "아무나 Solo 결합", "아무나보험". https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=아무나
Apps: none on iOS; Play 아무나스티커 (stickers).
6: literally "anyone is welcome," but the Korean register is "just anybody", with sexual and stranger-danger neighbors. Cut.

응원

표준국어대사전: 응원 (應援) 「1」 운동 경기 따위에서 선수들이 힘을 낼 수 있도록 도와주는 일 (노래, 손뼉치기) 「2」 곁에서 성원함. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=응원
나무위키: cheering that grew into cheerleading, related 응원가, 응원단, 서포터즈, 파도타기. https://namu.wiki/w/응원 Autocomplete: 응원봉, 응원 문구, 응원가, 응원단, 응원 이모티콘.
Apps: dominated by LED-sign and fan utilities: 아이돌 응원봉 (528 ratings), 모두의응원 LED 전광판 (300), LED 전광판 어플 (158); Play 응원도감 (pro-baseball cheer songs, 5.0), 정동원 응원봉, many LED boards.
Latin "Eungwon" reads poorly ("ung-won").
6: opens on the neutral 으; the meaning is supportive in a sports setting, which suits a club. Weak: generic everyday word, crowded results, awkward Latin, not cute.

Amity / 아미티

en.wiktionary: noun, "friendship; friendliness; mutual understanding and a peaceful relationship, especially between nations"; formal and literary; US /ˈæmɪti/; from Latin amicus via Old French; cognates Spanish amistad, French amitié, Italian amicizia. https://en.wiktionary.org/wiki/amity
en.wikipedia: Amity Island (Jaws), Amity Blight (The Owl House), Amity (a Divergent faction), many US towns, Amity University (several), AEON-Amity (Japanese English schools). https://en.wikipedia.org/wiki/Amity Autocomplete adds "amityville horror".
Korean autocomplete for 아미티: 아미티빌 호러, 아미 티셔츠 (BTS ARMY merchandise), 아미티 안심번호. A 40 to 60 year old Korean has no meaning for "amity".
Apps: Amity (Copiri, US, 75 ratings, 3.9), Amity: Sibling Harmony (4), Amity University (3), Amity Coffee (2); in KR the same apps with 0 ratings.
Light foreign check: Romance-language readers hear "friendship" (amistad, amitié, amicizia), a plus (my knowledge for the cognates beyond the Wiktionary list).
6: the softest English opening and an exact "friendship" meaning, but it is formal and opaque to the target audience and to the sport.

Oval / 오벌

en.wiktionary: "an elongated, round shape resembling an ellipse or an egg; (Australian) a sports field"; US /ˈoʊvəl/; from Latin ovum (egg). https://en.wiktionary.org/wiki/oval
Korean: autocomplete shows only product shapes (오벌 선글라스, 접시, 쉐입). The sound 오벌 is one vowel from 오발 (misfire; 오발탄, 오발 사고; my knowledge).
Apps: OVAL Key and OVAL Home (ImGATE, KR, 9 and 8 ratings), President & Oval Office News (463), Oval Care (10), Oval - Campus Life (2).
6: soft opening, but the meaning is a shape, not a feeling, and the shape is an egg (a rugby ball), not a tennis ball. Cut.

해달

표준국어대사전: 해달 (海獺) 「명사」『동물』 족제빗과의 바다짐승; "머리는 작고 둥근데"; lives in groups; fur trade is banned. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=해달
나무위키: sea otters wrap themselves in seaweed to avoid drifting and, without kelp, sometimes hold hands while sleeping; Korean web users tell otters from sea otters by their look; Chiikawa's Rakko is a sea otter; E-Mart's yellow shopping-bag mascot 투모 is a sea otter; no sea otters in Korean zoos or aquariums as of 2024. https://namu.wiki/w/해달 Wikipedia's photo caption: "Sleeping sea otters holding paws"; sea otters rest in groups called rafts. https://en.wikipedia.org/wiki/Sea_otter Autocomplete: "해달 손 잡고 자는 이유" (the fact is widely known).
Apps: 해달 Haedal - 데이트 지도, 커플 기록 (iOS Social, 3 ratings, 5.0), 해달 프리다이빙 (3), 기억해달 (2), Play 해달 소리, 떠있는 해달, 아기해달!. Shops: 해달스파, 해달네일, 해달씨.
Latin "Haedal" ("hay-dal"); in Japanese "hae" is the word for a fly and in Hindi dal is lentils (my knowledge, minor).
6: breathy "hae" opening; the strongest accepting story in the list: they hold hands so no one drifts away. A date-map app already uses the name.

병아리

표준국어대사전: 병아리 「1」 a young chicken 「2」 "신체나 재능, 학문, 기술 따위가 충분히 발달하지 못한 사람을 비유적으로 이르는 말" (병아리 기자, 병아리 아나운서, 병아리 배우); proverb 병아리 본 솔개. https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=병아리
나무위키: 햇병아리 = a newcomer; 병아리 as a cute label (the 1박2일 caption "병아리처럼 귀엽다" was yellow); 삐약이 as the nickname of 신유빈; the page notes some uses talk down to the young or unskilled. https://namu.wiki/w/병아리 Autocomplete: 병아리콩 dominates.
Apps: 병아리 한국어 스티커 (193 ratings), 병아리 키우기 2 (174), 병아리 방탈출 (45), PiyoHug; Play Rise of Chicks (4.9), 병아리 키우기.
Latin "Byeongari" is hard.
6: fuzzy yellow like a tennis ball, and a racket-sport nickname exists; but it opens on a stop consonant and says "beginner" to adults.

원앙

표준국어대사전: 원앙2 (鴛鴦) 「1」 mandarin duck, a protected natural monument 「2」 "금실이 좋은 부부를 비유적으로 이르는 말"; 원앙1 = 워낭 (a bell). https://stdict.korean.go.kr/search/searchResult.do?pageSize=50&searchKeyword=원앙
나무위키: 천연기념물 제327호; its fidelity image is called inaccurate (males mate with several females) and the real wedding bird was the goose; links mostly to marriage; other uses in food (원앙 훠궈), a mascot and a fashion brand. https://namu.wiki/w/원앙 Autocomplete: 원앙새, 원앙금침, 원앙 선물, 원앙닭발.
Apps: 원앙 - 말없이 통하는 우리만의 시그널 / 커플 메신저 (Zena Korea; iOS 2 ratings, Play 4.7), 종이 혼례복 3 원앙빚 (55).
Latin "Wonang" ("won-ang"; "won" reads as the currency); in Chinese 鴛鴦 yuānyāng, in Japanese おしどり (my knowledge): the pair image is shared across CJK.
6: the nearest in sound to 완두 (a w glide), and cute, but it says "married couple", not "club", and a couples app already holds it.

Extra soft-opening ideas (not asked; quick check only)

Korean, all open on a vowel or the glide 와 and read as togetherness:

어깨동무 (4 syllables): 「1」 "상대편의 어깨에 서로 팔을 얹어 끼고 나란히 섬" 「2」 a friend of the same age or height. The children's song "어깨동무 어깨동무 씨동무" gives it 40-60 nostalgia. Apps: 어깨동무 플랫폼 (Play 4.2); businesses 어깨동무어린이집, 한의원, 스토리움, a celebrity volunteer group. Long, but the arm-in-arm picture is exactly the sport crowd.
오순도순 (4): "정답게 이야기하거나 의좋게 지내는 모양"; iOS 오순도순 - 부부 공유 가계부 (1 rating); small businesses; no Play app.
와락 (2): "와락 껴안다" (a sudden hug) but also "와락 덤벼들다" (rush at). Opens on 와 like 완두. Businesses: 와락치킨 (a chicken franchise), 한과 와락, 성심당 와락; no app on iOS or Play. Mixed: the hug and the grab share the word.
어울림 (3): "두 가지 이상의 것이 서로 잘 조화됨"; the stock name of public sports and community centres (어울림체육센터, 어울림누리, 어울림플라자), so generic and institutional. iOS 스마트어울림 (33 ratings, 1.6), 어울림 스마트홈 (15, 2.3).
아우르다 / 아우름: "여럿을 모아 한 덩어리나 한 판이 되게 하다" (to gather many into one); 아우름 is used by clinics and an asset manager but is not a headword.
이음 (connection) is clean but generic (이음카드, KTX이음). English, from a quick US App Store scan only: Ohana (Hawaiian family; Ohana Island, 2,359 ratings; Ohana parental-control app, 326), Aloha (Aloha Browser, 314,491 ratings), Ubuntu (the Linux brand; few apps), Amigo (AmiGo Travel 1,227, AT&T amiGO 891). Ohana and Aloha carry warmth and open on a vowel but are Hawaiian cultural words with one large app each in the store.

Top 5 from the asked list (best first)

알알이 (4): the softest opening (a bare 아), "every single one counts", round like a grain or ball; Latin "Arari" reads easily; adverb, not noun, and spelling and sound differ ([아라리]).
아름 (4): an armful, the circle of two arms, is the embrace and the roundness in one word; opens on 아; reads as a girl's name and the crowded 아름다운 family.
해달 (4): the hand-holding sea otter is the strongest welcoming story; cute and short, opens on a breathy "hae"; a couples date-map app and the 수달 confusion are the baggage.
알콩 (4): round bean plus sweet harmony, opens on 아, two syllables; leans couple or family and autocorrects to 알코올.
응원 (3): opens softly, means "I'm backing you", and is a sports word; generic, crowded with LED-sign apps, awkward Latin, not cute. Just outside: 원앙 (the closest sound to 완두, but married-couple-coded), 울타리 (shelter, but a fence).

Outright cuts

아무나: sexual, stranger-danger and "just anybody" associations.
Oval / 오벌: a shape, not a feeling; egg not ball; one vowel from 오발 (misfire).
얼싸 (as a name): shares the sarcasm sense of 얼씨구; keep 얼싸안다 for copy. Weak, not cut: 한깍지 and 손깍지 (the pod is lost on most readers; hand-holding is couple-coded), 병아리 (fails the soft-opening test and says "beginner"), Amity (opaque to the audience).
