Geopjaengi (겁쟁이) and the -쟁이 suffix: how Korean turns a trait into a person

PENTAGON’s comeback landed in my feed as an English headline first, the Hangul a beat behind it: ten years, the reunion I’d stopped expecting, a song called “Coward.” I filed it under nostalgia and kept scrolling. It was the second post, a fan translation with the actual title attached, 겁쟁이, that made me stop — because I already knew the first half of that word, and the second half didn’t look like anything I’d studied.

겁 I had. Fear, or more precisely the kind of fear that makes you hesitate — I’d met it in 겁나다 and 겁먹다. 쟁이 I hadn’t, not as its own piece. It turned out to be doing exactly the job you’d guess from the English title: turning a trait into the person who has it.

What does -쟁이 mean, and why does 겁쟁이 mean “coward”?

-쟁이 attaches to a word for a quality, habit, or behavior and produces a noun for the person who has it — usually with a teasing or belittling edge. 겁 is fear; 겁쟁이 is the person who has too much of it. The standard dictionary is direct about the tone: it defines 겁쟁이 as “겁이 많은 사람을 낮잡아 이르는 말” — “a belittling way to refer to a person who is easily frightened” (국립국어원 표준국어대사전, stdict.korean.go.kr). That belittling edge is baked into the suffix, not just this one word, which is worth knowing before you reach for it.

PENTAGON’s own use leans into that self-deprecation rather than around it. According to the Korea Daily’s coverage of the release, the song — produced by member Kino, who co-wrote it with Kim Eana and Baek Eun-byeol — is about wanting to reconnect with someone you’ve missed and being too afraid to reach out, which mirrors the group’s own return to fans after three years apart (Korea Daily, “Pentagon reunion — 10th Anniversary Single ‘Coward’”). Calling yourself the 겁쟁이 in that story, not the other person, is the same move as an English speaker saying “I chickened out” — owning the flinch instead of accusing someone else of it.

-장이 or -쟁이? The pair that trips up Korean speakers too

Here’s where a learner’s dictionary habit works against them: typing “jang-i” and “jaeng-i” into a search bar mostly returns the same confusion Korean speakers themselves ask about. The two suffixes sound almost identical and split along one line: -장이 names someone with a hands-on trade skill; -쟁이 covers everything else. The rule comes from Standard Language Regulation Article 9 (표준어 규정 제9항), and the National Institute of Korean Language’s own guidance narrows “trade skill” specifically to manual craft work (수공업적인 기술자) — not just any expertise (국립국어원 온라인가나다, korean.go.kr):

Suffix	Covers	Examples
-장이	hands-on trade skill	미장이 (plasterer), 대장장이 (blacksmith), 땜장이 (tinker), 칠장이 (lacquer worker), 유기장이 (brassware maker)
-쟁이	trait, habit, or anything else	겁쟁이 (coward), 고집쟁이 (stubborn person), 욕심쟁이 (greedy person), 멋쟁이 (stylish person), 깍쟁이 (stingy, calculating person)

The twist that makes this a genuinely confusable pair, and not just a spelling rule: some jobs that sound skilled still take -쟁이, because “manual trade” is read narrowly. The same institute guidance lists 점쟁이 (fortune teller), 글쟁이 (writer, also belittling), and 환쟁이 (painter, also belittling) as -쟁이 words, not -장이 — fortune-telling, writing, and painting aren’t manual crafts by this definition, whatever skill they take. A Korean-language newspaper column on exactly this pair makes the same split with a different example set, which is a good sign the rule is stable rather than a one-source quirk (경향신문, “‘장이’와 ‘쟁이’”).

The reusable part: almost any trait can take -쟁이

This is the piece worth keeping past the song. -쟁이 is productive — you’re not memorizing a fixed list, you’re learning a slot. Take a noun for a quality or habit, add -쟁이, and you get “the person who’s like that”:

• 겁 (fear) → 겁쟁이 (coward)
• 고집 (stubbornness) → 고집쟁이 (stubborn person)
• 욕심 (greed) → 욕심쟁이 (greedy person)
• 멋 (style) → 멋쟁이 (stylish person)

That last one is the exception worth flagging on its own. 멋쟁이 keeps the suffix’s shape but not its edge — in ordinary use it reads as a compliment, not an insult, closer to “sharp dresser” than “show-off.” 깍쟁이 sits in between: it can mean someone genuinely stingy, or — said to a friend, with the right tone — someone who’s just a little too polished and self-interested to be annoyed at. (Worth knowing: the standard dictionary actually classifies 깍쟁이 as a single word rather than a 깍 + -쟁이 formation, so treat it as a word to know on its own rather than proof the pattern is fully open-ended.) None of that is predictable from the suffix alone. What’s predictable is the shape: quality noun in, “the person who has it” out, teasing by default, softened only by who’s saying it and how.

What to take from this

• -쟁이 turns a trait, habit, or quality into the person who has it, usually with a teasing or belittling edge — 겁 (fear) becomes 겁쟁이 (coward), the title of PENTAGON’s 2026-09-11 comeback single.
• The near-identical -장이 is reserved for hands-on manual trades (미장이, 대장장이) — and the split catches Korean speakers too, since skilled work like fortune-telling and writing still takes -쟁이 (점쟁이, 글쟁이).
• The suffix is productive: any quality noun can plug into the slot, though the resulting word’s tone — insult, tease, or genuine compliment like 멋쟁이 — isn’t something the suffix decides on its own.

Rules like this one are easy to read and hard to keep: you’ll recognize -쟁이 the next time a caption uses it, and still hesitate over whether to reach for it yourself. That gap between recognizing a pattern and reaching for it live is the argument behind how I improved my Korean listening. up103 builds practice out of the notes you already keep, so a suffix like this comes back at you inside a real sentence instead of staying a rule you read once.
