Questions & Answers about eojeneun eokkaega apaseo sonmok seuteurechingman jogeum haesseo.

Why is 어제 followed by 는 in 어제는?

는 here marks 어제 as the topic and adds a slight contrastive feeling.

So 어제는 is not just yesterday in a neutral sense. It often feels like:

• as for yesterday
• yesterday, at least
• yesterday, in that situation

In context, it can imply something like:

• Yesterday, my shoulder hurt, so I only did a little wrist stretching.
• maybe contrasting with today, usually, or some other day

If you said just 어제, the sentence would still make sense, but 어제는 sounds a bit more natural when setting the scene or contrasting yesterday with another time.

Why is it 어깨가 아파서 and not 어깨는 아파서?

In 어깨가 아파서, the particle 가 marks 어깨 as the thing that hurts.

With body parts and physical conditions, Korean very often uses:

• X가 아프다 = X hurts

So:

• 머리가 아파요 = My head hurts
• 배가 아파요 = My stomach hurts
• 어깨가 아파요 = My shoulder hurts

Using 는 instead would shift the nuance. 어깨는 아파서 could sound contrastive, like:

• As for my shoulder, it hurt...
• maybe implying something like but my wrist was okay

So 가 is the normal, straightforward choice here.

What does 아파서 mean here? Is it a tense form?
