Questions & Answers about eojeneun neomu pigonhaeseo angyeongeul sseun chaero jamosdo an garaipgo jamdeureosseo.
어제는 means as for yesterday or yesterday with a topic nuance.
Using 는 does a little more than just mark time:
- It sets yesterday as the topic/background for the sentence.
- It can give a slight contrastive feeling, like yesterday in particular.
So:
- 어제 너무 피곤해서... = Yesterday, because I was so tired...
- 어제는 너무 피곤해서... = As for yesterday / Yesterday especially, I was so tired...
In many cases, both are natural, but 는 helps frame the whole situation.
Here it basically means so tired or very tired, with the idea that this tiredness led to what happened next.
The grammar -아서/어서 often shows a cause:
- 피곤해서 = because I was tired / being tired, so...
So 너무 피곤해서 is not just describing tiredness. It means:
- I was so tired that...
- Because I was very tired...
Also, in modern spoken Korean, 너무 is often used simply as an intensifier, not only in the strict English sense of too.
