When you want to explain the reason or cause for something, you can use the conjunction '아서' (aseo). It connects two clauses, where the first clause states the reason and the second clause states the result or consequence. Think of it like saying 'because' or 'so' in English. This conjunction can also be used to indicate a sequence of actions, meaning 'and then' or 'after doing something'.
For example, if you say '비가 와서 집에 있었어요' (biga waseo jibe isseosseoyo), it means 'Because it rained, I stayed at home.' Here, the rain is the reason for staying home. Another example for sequence is '밥을 먹어서 힘이 났어요' (babeul meogeoseo himi nasseoyo), which translates to 'I ate, so I got energy' or 'After eating, I gained strength.'
Remember that '아서' is attached to the stem of the verb or adjective. If the stem ends in a vowel 'ㅏ' or 'ㅗ', you use '아서'. Otherwise, you use '어서'. If the stem ends in '하다', it changes to '해서' (haeseo).
§ What does it mean and when do people use it?
The Korean conjunction -아서/어서 (aseo/eoseo) is a super common and important grammatical structure you'll encounter a lot. It has a few main uses, but they all generally revolve around connecting two clauses, with the first clause providing a reason, cause, or a sequential action for the second clause. Think of it as meaning 'because,' 'so,' or 'then' in English, depending on the context.
You attach -아서 to a verb or adjective stem. The choice between -아서 and -어서 depends on the last vowel of the stem. If the last vowel is ㅏ (a) or ㅗ (o), you use -아서. For all other vowels, you use -어서. If the stem ends in 하다 (hada), it changes to 해서 (haeseo). This is a common pattern in Korean grammar, so it's good to get used to it!
- Meaning 1
- Reason or Cause (Because, Since)
This is probably the most frequent use of -아서/어서. It indicates that the first clause is the reason or cause for the action or state in the second clause. It's similar to using 'because' or 'since' in English.
비가 와서 집에 있었어요.
Translation hint: It rained, so I stayed home. (Because it rained, I stayed home.)
피곤해서 일찍 잤어요.
Translation hint: I was tired, so I slept early. (Because I was tired, I slept early.)
- Meaning 2
- Sequential Action (Then, And then)
Another common use of -아서/어서 is to indicate a sequence of actions, where the first action must happen before the second. It implies a natural progression or that the second action depends on the completion of the first. In this case, it's often translated as 'and then' or simply 'then'.
집에 가서 밥을 먹었어요.
Translation hint: I went home and then ate. (I went home, then ate.)
책을 읽어서 잠이 들었어요.
Translation hint: I read a book and then fell asleep. (I read a book, then fell asleep.)
- Meaning 3
- Greetings and Thanks
You'll also hear -아서/어서 in common greetings and expressions of gratitude. In these cases, the first part often implies a reason for the greeting or thanks.
- 만나서 반갑습니다 (mannaseo bangapseumnida): Nice to meet you. (Because I met you, I'm glad.)
- 고마워서 드려요 (gomawoseo deuryeoyo): I'm giving this to you because I'm thankful.
Understanding -아서/어서 is a big step in becoming more fluent in Korean. Pay attention to how it's used in different contexts, and you'll quickly get the hang of it!
रोचक तथ्य
This conjunction is often used for actions that happen in sequence, where the first action directly leads to or enables the second.
ज़रूरी व्याकरण
Use -아서/어서 to connect two clauses where the first clause is the reason or cause for the second clause. The two clauses must have a logical cause-and-effect relationship.
날씨가 좋아서 산책했어요. (The weather was good, so I went for a walk.)
-아서/어서 can also indicate a sequence of actions, where the first action must be completed before the second action can occur. There is no intention or command in the second clause.
학교에 가서 공부했어요. (I went to school and studied.)
When the stem of the preceding verb or adjective ends in a vowel ㅏ or ㅗ, use -아서. For all other vowels and for words ending in 하다, use -어서. If the 하다 verb is part of a compound (e.g., 공부하다), the 하다 changes to 하여서, which is often shortened to 해서.
보고 싶어서 연락했어요. (I missed you, so I contacted you.) / 공부해서 시험을 잘 봤어요. (I studied, so I did well on the exam.)
You cannot use -아서/어서 with imperative (commands) or propositive (suggestions) endings in the second clause. Use -(으)니까 instead for those situations.
비가 와서 집에 있어요. (It's raining, so I'm staying home.) - Incorrect: 비가 와서 집에 가세요. (It's raining, so please go home.)
The tense (past or future) is only expressed in the final verb of the sentence. The verb or adjective before -아서/어서 remains in its stem form.
피곤해서 일찍 잤어요. (I was tired, so I slept early.)

While both mean 'because,' '아서' is for direct reasons/sequences and cannot be used with imperatives/propositives. '-(으)니까' is for discovered reasons and can be used with imperatives/propositives.
Both mean 'because,' but '-기 때문에' is more formal and objective, emphasizing the cause more strongly than '아서.'
'아서' is a conjunction connecting clauses within a sentence, showing direct cause/sequence. '그래서' is an adverb connecting two separate sentences, introducing a result.

Many learners confuse '아서' with other Korean conjunctions that also mean 'because' or 'so,' such as '으니까' (eunikka) or '기 때문에' (gi ttaemune). The key difference lies in the nuances of reason and sequence.
'아서' is used when the first clause is a direct reason or cause for the second clause, often with a sense of natural flow or consequence. It cannot be used with imperative or propositive sentences. It also indicates a sequence of actions where the first action must happen before the second.
날씨가 좋아서 산책했어요. (The weather was good, so I went for a walk.)
When combined with '오다' (to come) or '가다' (to go) as '어서 오다' or '어서 가다,' it can be confused with a similar-sounding adverb '어서' meaning 'quickly' or 'at once.'
In the context of '어서 오다' or '어서 가다,' the '어서' here is actually the shortened form of '아/어서' acting as a conjunction, implying 'come/go and then do something' or 'because you are coming/going.' It's not the adverb meaning 'quickly.'
집에 가서 밥 먹었어요. (I went home and ate.)
This is another common conjunction for 'because' or 'so' that can be confused with '아서.'
While '아서' expresses a direct cause, '-(으)니까' is often used when the speaker discovers a reason or result. It can also be used with imperative or propositive sentences, which '아서' cannot. It often implies the speaker's subjective judgment or feeling.
비가 오니까 우산 가져가세요. (It's raining, so take an umbrella.)
This is another 'because' conjunction that learners often mix up with '아서' and '-(으)니까.'
'-기 때문에' is a more formal and objective way to express a reason or cause. It can be used for both positive and negative reasons and is often found in written language or more formal speech. It emphasizes the cause and effect more strongly than '아서.'
교통 체증 때문에 늦었어요. (I was late because of the traffic jam.)
'그래서' also means 'so' or 'therefore,' leading to confusion when choosing between '아서' and '그래서.'
'그래서' is an adverb that connects two separate sentences. It introduces a result or consequence based on a previously stated fact. '아서', on the other hand, is a conjunction that connects two clauses within a single sentence, showing a direct cause-and-effect relationship or sequence.
비가 왔어요. 그래서 집에 있었어요. (It rained. So, I stayed home.)

다음 문장 중 '아서'의 사용이 적절하지 않은 것은 무엇입니까?
'슬프다'와 '기분이 좋다'는 서로 상반되는 감정이므로, '슬퍼서 기분이 좋아요'는 논리적으로 '아서'의 용법에 맞지 않습니다. '슬프지만 기분이 좋아요'처럼 다른 연결어를 사용해야 합니다.
