-어 버리다
-어 버리다: Completion, Regret, and Finality
Auxiliary verb attached to verbs via -아/어: indicating that an action has been completely, thoroughly, and irreversibly carried out, typically packaging the speaker's emotional reaction to that completion — either: (1) sadness, disappointment, or regret over an unintended or unfortunate event; or (2) a profound sense of psychological relief, catharsis, or unburdening.
How to form it
| When | Form | Example |
|---|---|---|
| Stem with bright vowels (ㅏ, ㅗ) | Stem + -아 버리다 | 가 버리다 / 잃어버리다 / 사 버리다 |
| Stem with dark/neutral vowels (ㅓ, ㅜ, ㅡ, ㅣ, etc.) | Stem + -어 버리다 | 먹어 버리다 / 잊어 버리다 / 쏟아 버리다 |
| 하다 verbs | Stem + -해 버리다 | 말해 버리다 / 끝내 버리다 / 털어 버리다 |
| Past tense completion (Overwhelmingly common in real speech) | Stem + -아/어 버렸다 / 버렸어요 | 다 먹어 버렸어요 / 비밀을 말해 버렸어요 |
In Korean, verbs do not merely report physical actions; they frequently package the speaker’s psychological stance toward those actions. The auxiliary verb construction -아/어 버리다 is the undisputed master of irreversible emotional completion:
$$ \text{Action Verb Stem} + \textbf{-아/어 버리다} \longrightarrow \text{“100% Completed, Irrevocable, and Done — With Feeling!”}$$
While its lexical origin comes from the independent verb 버리다 (to throw away / discard, as in 쓰레기를 버리다), when operating as an auxiliary verb after -아/어, it expresses that an action has been carried out so thoroughly that there is no turning back.
Crucially, -어 버리다 possesses a dual emotional polarity:
- The Polarity of Regret & Remorse (아쉬움 / 후회): “Oh no, I went and did it… / It’s done and I can’t undo it.”
- The Polarity of Relief & Liberation (후련함 / 부담 해소): “Phew! I finally dispatched that burden and washed my hands of it!”
1. Emotional Polarity 1: Regret, Loss, and Irreversibility
When an accident occurs, a secret slips out, or a moment of weakness overtakes you, -어 버리다 captures the sinking feeling that the past is sealed:
다이어트 중이었는데 야식의 유혹을 못 이기고 피자를 다 먹어 버렸어요.
I was on a diet, but I couldn't resist the temptation of a late-night snack and went and ate all the pizza!
(Regret: The pizza is consumed; the diet is broken; I feel guilty).
아끼던 찻잔을 설거지하다가 바닥에 떨어뜨려 깨뜨려 버렸다.
While washing the dishes, I dropped and broke the teacup I cherished so much.
(Loss: The cup is shattered into pieces; it can never be restored).
기차가 1분 전에 이미 출발해 버려서 다음 차를 기다려야 합니다.
The train already departed a minute ago [and is completely gone], so I have to wait for the next one.2. Emotional Polarity 2: Sweet Relief and Catharsis
When you finish an exhausting examination, submit a grueling tax report, or finally shake off a lingering obsession, -어 버리다 conveys intoxicating psychological lightness:
일주일 동안 나를 괴롭히던 프로젝트 보고서를 방금 과장님께 제출해 버렸습니다!
I just went ahead and submitted the project report that had tormented me for a week to the section chief!
(Relief: It is off my desk; I am free!).
지난 일에 대한 미련과 후회는 오늘 밤으로 모두 털어 버리자.
Let's completely shake off all lingering attachments and regrets over the past tonight!
(Catharsis: Casting aside psychological burdens).
골치 아픈 계약 문제는 오늘 회의에서 시원하게 결론을 내 버렸어요.
We went ahead and reached a decisive conclusion on that headache-inducing contract issue in today's meeting.3. Structural Matrix: ‘-어 버리다’ vs. ‘-고 말다’ vs. ‘-어 놓다/두다’
| Construction | Core Focus | Narrative Flavor | Typical Situation |
|---|---|---|---|
| -어 버리다 | Irreversible completion + Emotional reaction | Spontaneous, decisive, or sudden | 다 먹어 버렸다. (Ate it all with regret/relief). |
| -고 말다 | Eventual culmination after struggle/resistance | Agonizing path toward unavoidable outcome | 결국 헤어지고 말았다. (Ended up breaking up in the end). |
| -어 놓다/두다 | Doing an action and preserving the ready state | Forward-looking maintenance for future utility | 문을 열어 놓았다. (Opened it and kept it open on purpose). |
4. Sociolinguistic Etiquette in the Workplace
Because -어 버리다 inherently carries subjective emotional color, using it when reporting mistakes to executive superiors can backfire:
- ⚠️ “부장님, 제가 중요한 고객 데이터베이스를 삭제해 버렸습니다.”
- Unintended Nuance: “Director, I went and deleted the database! It’s gone!” This can sound flippant, dramatic, or resigned.
- ✅ “부장님, 제가 실수로 고객 데이터베이스를 삭제하였습니다. 즉시 백업 복구를 진행하겠습니다.”
- Professional Nuance: Clear, objective accountability followed immediately by solution-oriented action.
5. Summary Diagnostic Checklist
When applying -어 버리다:
- Is the action 100% finished and irreversible? Use -어 버리다 to seal the completion.
- Does the situation involve regret or remorse? It will naturally communicate: “I can’t believe I went and did that.”
- Does the situation involve unburdening or finishing a difficult chore? It will communicate: “Phew! Glad that’s finally off my chest!”
- Is it an official corporate incident report? Keep the language objective with plain past -았습니다/었습니다, avoiding emotional auxiliary color.

Common questions
Is -어 버리다 always negative?
No! This is one of the most common learner misconceptions. The National Institute of Korean Language (우리말샘 Sense 「008」) explicitly defines the auxiliary as conveying either regret OR the feeling of relief that a burden is gone: '걱정을 털어 버렸다' (I shook off my worries), '밀린 빨래를 다 해 버렸다' (I finished all the piled-up laundry!).
What is the difference between '-어 버리다' and '-고 말다'?
Both express completion, but their narrative lens differs: -어 버리다 emphasizes the sudden, decisive, or irreversible nature of the act (often in spoken everyday contexts). -고 말다 emphasizes the long, agonizing struggle, temptation, or resistance that preceded the eventual unfortunate outcome ('결국 포기하고 말았다' = After struggling for so long, I ended up surrendering in the end).
Is '잊어버리다' (to forget) a grammar pattern or a single word?
It started as the verb 잊다 (to forget) + -어 버리다, but over centuries it became so universally entrenched that it is now listed in the dictionary as a single, indivisible lexical headword: 잊어버리다 (to forget completely). You write it without any spaces.
Can -어 버리다 attach to adjectives?
No. -어 버리다 strictly requires action verbs because it describes the dynamic execution and completion of a physical or mental action. You cannot say *예뻐 버렸다 (X) or *추워 버렸다 (X).
