Core Pattern Rule: Warning with -다가는
This pattern is used to warn that if an action continues, a negative consequence will follow. It's a way of saying, "If you keep doing X, then Y (something bad) will happen."
Meaning & Usage
Meaning: Expresses a strong warning or predicts a negative outcome based on a continued action or habit.
When to use: Use it when you see someone doing something that you believe will lead to trouble, regret, or an undesirable result. The second clause is almost always negative.
Formation
Attach -다가는 directly to the verb stem. It doesn't matter if the stem ends in a vowel or a consonant.
먹다 (to eat) → 먹다가는
하다 (to do) → 하다가는
놀다 (to play) → 놀다가는
그러다가는 큰일 나. / 계속 먹다가는 돼지 된다. / 미루다가는 후회해.
Synonyms & Differences: -다가는 vs. -(으)면
While both patterns can be translated as "if," they have very different nuances and are not interchangeable.
-다가는 (Strong Warning)
Focus: Used almost exclusively to warn about a negative consequence resulting from a continued action.
Implication: The action is likely already happening or is a habit, and the speaker strongly advises against it.
Example: 거짓말하다가는 신용을 잃어. (If you keep lying, you'll lose trust.) - This is a direct warning.
-(으)면 (General Condition)
Focus: A neutral conditional for any situation—positive, negative, or neutral. It simply states a condition and its result.
Implication: It doesn't carry the strong sense of warning or the idea of a continuing action.
Example: 거짓말하면 신용을 잃을 수 있어. (If you lie, you can lose trust.) - This is a general statement of fact.
Key takeaway: Use -다가는 for specific, urgent warnings about ongoing behavior. Never use it for positive outcomes.
돈을 막 쓰다가는 거지 돼. / 공부 안 하다가는 시험 망쳐. / 열심히 공부하면 시험에 합격할 거야.
Native Nuance & Mistakes
To sound more natural, keep these points in mind.
Nuance of Certainty
-다가는 implies a very high probability that the negative outcome will happen. It's not just a vague possibility; it's presented as an almost certain result if the behavior doesn't change. This gives the warning its strength.
Common Mistake: One-Time Actions
This pattern is for repeated or ongoing actions. It sounds awkward when used for a single, completed event in the past.
Incorrect: 어제 과속하다가는 사고가 났어. (X)
Correct: 어제 과속해서 사고가 났어. (O - Because I sped yesterday, I got into an accident.)
Common Mistake: Positive Outcomes
As covered before, never use -다가는 for a positive result. It is fundamentally a pattern for warnings.
Incorrect: 그렇게 열심히 일하다가는 승진할 거예요. (X)
Correct: 그렇게 열심히 일하면 승진할 거예요. (O - If you work that hard, you'll get promoted.)
핸드폰만 보다가는 눈 나빠져. / 안 자다가는 쓰러져. / 계속 마시다가는 필름 끊겨.
Politeness & Formality
The pattern -다가는 itself is neutral. The overall politeness of the sentence is determined by the final verb ending.
Casual Language (반말)
Sentences ending in -어/아 are casual. You'd use this with close friends, family, or people younger than you.
Example: 그러다가는 큰일 나. (You'll be in big trouble if you keep doing that.)
Polite Language (해요체)
Sentences ending in -어요/아요 are polite. This is the standard form for most daily conversations with colleagues, acquaintances, or elders.
Example: 그러다가는 큰일 나요.
The warning is the same, but the delivery changes based on your relationship with the listener.
놀다가는 거지꼴 못 면해. / 놀다가는 거지꼴 못 면해요. / 과속하다가는 사고 나. / 과속하다가는 사고 나요.
