안녕하세요! Today we’re covering 아/어/여서 — a really versatile grammar connector that you’ll need to know. Depending on context, it can mean “because,” “so,” or “and then.” It’s one of those things that once you understand it, you’ll wonder how you ever spoke Korean without it!
Understanding 아/어/여서
Before we can master the art of crafting compelling Korean sentences with “아/어/여 서,” let’s get up close and personal with this grammatical superhero. Picture “아/어/여 서” as the life of the party, connecting everyone and making sure the conversation flows without a hitch. But what exactly is “아/어/여 서,” and why is it so crucial in the Korean language? Let’s break it down.
What is 아/어/여서?
“아/어/여 서” is a conjunctive particle used in Korean to link clauses together, showing a relationship of cause and effect or a sequence of actions. Think of it as the bridge that connects two islands, allowing for smooth travel between them. In the land of grammar, these islands are your ideas, and “아/어/여 서” ensures they’re not isolated but part of a scenic and cohesive narrative.
Conjugation
-아서
-어서
-여서
VERB STEM + 아/어/여서
To know which of the above you need to use, follow the rules below which are the same as for the present tense conjugation, we just add 서 at the end;
- Take a verb i.e. 하다
- Drop “다” i.e. 하
- Add the appropriate ending based on the below rules (in this case it becomes 해서)
- If the last vowel is ㅏ or ㅗ, add 아서
- If the last vowel is not one of the above, add 어서
- Only 하 is followed by 여서 and becomes 해서 (always the case)
Every single verb ends with 다. To conjugate them to a present tense i.e. 가다 (To go);
The below list summarises the rules (if you check the present tense conjugation rules all we are doing here is replace the “요” with “서”);
- ㅏ+ㅏ= ㅏ (i.e. 자다. 자다 –> 자 + 아서 –> 자아서 –> 자서)
- ㅓ+ㅓ=ㅓ (i.e. 서다. 서다 –> 서 + 어서 –> 서어서 –> 서서)
- ㅗ+ㅏ =ㅘ (i.e. 오다. 오다 –> 오 + 아서 –> 오아서 –>와서)
- ㅜ+ㅓ=ㅝ (i.e. 주다. 주다 –> 주 + 어서 –> 주어서 –> 줘서)
- ㅕ+ㅓ=ㅕ (i.e. 켜다. 켜다–> 켜 + 어서 –> 켜어서 –> 켜서)
- ㅣ+ㅓ=ㅕ (i.e. 가지다. 가지다 –>가지 + 어서 –> 가지어서 –>가져서)
- ㅐ+ㅓ=ㅐ (i.e. 내다. 내다 –> 내 + 어서 –> 내어서 –> 내서)
- ㅔ+ㅓ=ㅔ (i.e. 세다. 세다 –> 세 + 어서 –> 세어서 –> 세서)
Usage
The primary function of “서” is to indicate a relationship between the two clauses it connects. It implies that the first clause caused or led to the second clause. By using “서” we establish how one part of the sentence relates to the other part. In other words, why do we combine them together.
1. To indicate the order in which two things happen.
You’re laying out events in the order they happened, guiding your listener or reader through the storyline.
When used in this way, “서” implies that the second part of the sentence happened after the first part. It is similar in meaning to the English conjunctions “then” or “and.” For example, in the sentence “학교에 가서 친구를 만났어요” which translates to “I went to school and met my friend,” the first clause “학교에 가서” means “I went to school,” and the second clause “친구를 만났어요” means “I met my friend.”
Examples
- 일어나서 샤워를 했어요 – I woke up and I took a shower.
- 도서관에 가서 책을 읽을거예요 – I will go to the library and read a book.
- 친구를 만나서 같이 밥을 먹을 거예요 – I will meet my friend and eat together.
2. To show that one thing caused another thing to happen.
You’re showing that action A leads to action B, like a domino effect in the narrative world.
When used in this way, “서” implies that the first part of the sentence caused or led to the second part. It is similar in meaning to the English conjunctions “because,” “since,” or “so.” For example, in the sentence “비가 와서 우산을 가져왔어요” which translates to “It rained, so I brought an umbrella,” the first clause “비가 와서” means “because it rained,” and the second clause “우산을 가져왔어요” means “I brought an umbrella.”
Examples
- 아까 밥을 먹어서 배 안 고파요. – I ate a while ago so I am not hungry.
- 하루종일 운전해서 너무 피곤해요 – I was driving all day so I am very tired.
- 내일은 바빠서 같이 못 가요 – I am busy tomorrow so I cannot go with you.
Nuances in Usage
While “아/어/여 서” is a common way to express causality, it’s important to note that it often carries a slightly softer, more nuanced implication than simply saying “because.” It integrates the cause and effect into a fluid narrative, rather than presenting them as stark, separate facts.
