Overview
The connective ending -자마자 is used to express that the action or event in the second clause occurs immediately after the action or event in the first clause. It emphasizes a very short or non-existent time gap between the two events.
Usage
-자마자 connects two clauses, indicating a direct and instantaneous sequence. The action described in the second clause happens right after the completion of the action in the first clause. It is often used to describe a quick reaction, a direct consequence, or a habitual immediate action.
- It can be used with both past and present tense verbs in the first clause, but the -자마자 form itself does not change. The overall tense of the sentence is determined by the final verb.
- The subjects of the two clauses can be the same or different.
- It cannot be used with imperative (e.g., -(으)세요) or propositive (e.g., -(으)ㅂ시다) endings in the main clause, as it describes a factual sequence of events rather than a command or suggestion.
Conjugation Rules
-자마자 is attached directly to the verb stem. There are no special rules for consonant or vowel endings, nor are there any irregular conjugations.

Comparison with similar expressions:
- -고 나서: This simply indicates that one action happens after another, but it allows for a significant time gap between the two actions. -자마자 specifically emphasizes immediacy.
- 밥을 먹고 나서 커피를 마셨어요. (After eating, I drank coffee. - Implies a possible break.)
- 밥을 먹자마자 커피를 마셨어요. (As soon as I ate, I drank coffee. - Implies no break.)
- -은/는 후에: Similar to -고 나서, this also means "after" and implies a completion of the first action before the second, often with a potential time gap.
- -자: This ending also expresses immediate succession, similar to -자마자. However, -자마자 is generally more common in everyday spoken Korean for simple immediate sequences and tends to emphasize the moment of transition. -자 can sometimes carry a slightly more formal or literary nuance, or imply that the second action is a direct, often inevitable, consequence or reaction to the first. For example, "해가 뜨자 새들이 지저귀기 시작했다" (As soon as the sun rose, birds began to chirp) sounds more natural with -자. For personal, immediate reactions, -자마자 is often preferred.

Common usage contexts: -자마자 is frequently used to describe situations where someone reacts quickly, feels a sudden emotion, or performs an action without hesitation immediately after another event.
