-(아/어/여)서 because, for the reason of
August 21, 2009 by tailieutienghan
This grammatical structure indicates cause or reason for a consequence. It is a non-final ending, and thus a consequential sentence is typically introduced after this structure. However, it is commonly used as a sentence ending, because many times, the consequential sentence can be inferred. It is used mostly with descriptive verbs (some action verbs are exceptions).
[verb] + -(아/어/여)서
괜찮다 (gwenchanta) – to be alright, to be ok
괜찮 (gwenchanh) – verb stem
괜찮 + 아서
괜찮아서… – because it's alright…
Sentence1 서, Sentence 2
Sentence 1 = (the reason)
Sentence 2 = (consequence)
Sentence 1 provides reason for Sentence 2.
1.바빠서, 못 왔어요. (bappaseo, mot wasseoyo.)
I was busy, so I couldn't come.
2.술이 좋아서, 어제도 술 마셨어요. (sul-i johaseo, eoje-do sul masyeosseoyo.)
Because alcohol is good, I drank again yesterday.
3.예뻐서 전화했지. (yeppeoseo jeonhwahaetji.)
Because you're pretty, I called.
A situation where the consequential sentence must be implied:
아버지: 왜 늦게 왔어? (Why did you come late?)
아들: 차가 막혀서… (Because there was traffic…)
The ending of the sentence should be: 늦었어. (I was late.)
