Questions & Answers about chuwoseo soni tteollyeoyo.

Why is it 추워서 and not 춥어서?

Because 춥다 is a ㅂ-irregular adjective.

When a ㅂ-irregular stem is followed by a vowel-starting ending like -어서, the ㅂ changes to 우:

• 춥다 → 추워서
• 덥다 → 더워서
• 어렵다 → 어려워서

So:

• 춥다 + -어서 → 추워서

This is one of the first irregular patterns Korean learners meet.

What does -서 mean in 추워서?

Here, -아서/-어서 means because or so. It connects the reason to the result.

So the structure is:

• 추워서 = because it’s cold / because I’m cold
• 손이 떨려요 = my hands are trembling

In this sentence, -서 gives the cause of the trembling.

Does 추워서 mean because it’s cold or because I’m cold?

It can feel like either in English, and that is normal.

Korean often leaves the subject unstated when it is obvious from context. So 추워서 can be understood as:

• because it’s cold
• because I’m cold

In this sentence, both lead to basically the same idea. Korean does not always force you to choose as explicitly as English does.

Why is there no word for before ?
