Core Pattern Rule: -기가 무섭게 (Immediately After)
This pattern emphasizes that a second action happens immediately after a first one, with an extremely short time gap.
Meaning & Usage
Meaning: "As soon as," "the moment that," or "right after."
Nuance: The literal translation is "as if scared of [verb]-ing," which creates a vivid image of the second action happening so fast it's almost chasing the first. It adds a sense of surprise or drama to the sequence of events.
Formation
Rule: Attach -기가 무섭게 directly to a verb stem.
Verb Stem + 기가 무섭게
받다 (to receive) → 받기가 무섭게
눕다 (to lie down) → 눕기가 무섭게
끝나다 (to end) → 끝나기가 무섭게
Tense: The overall tense of the sentence is determined by the final verb, not the -기가 무섭게 part.
월급 받기가 무섭게 사라져. / 눕기가 무섭게 잠들었어. / 음식이 나오기가 무섭게 먹었어요. / 회의가 끝나기가 무섭게 나갔어.
Synonyms & Differences: vs. -자마자
Both -기가 무섭게 and -자마자 translate to "as soon as," but they have different nuances.
-자마자 (Neutral Sequence)
Usage: This is the most common and neutral way to express that one action follows another. It simply states the sequence of events without adding any special emphasis or emotion.
Example: 집에 도착하자마자 손을 씻었어요. (I washed my hands as soon as I got home.) This is a simple, factual statement.
-기가 무섭게 (Emphatic Immediacy)
Usage: This pattern is more expressive and dramatic. It highlights the surprising or startling speed of the second action. It's used more in spoken Korean to add flavor to a story.
Example: 경찰을 보기가 무섭게 도망쳤어요. (He ran away the instant he saw the police.) This emphasizes a frantic, immediate reaction.
Key Takeaway: Use -자마자 for general sequences. Use -기가 무섭게 when you want to emphasize how incredibly fast and immediate the second action was.
회의가 끝나기가 무섭게 나갔어. / 회의가 끝나자마자 나갔어. / 벨이 울리기가 무섭게 받았어요. / 벨이 울리자마자 받았어요.
