Questions & Answers about sonmogi apaseo mauseureul orae mos sseoyo.

Why is 손목이 아파서 used here, and what does -아서 / -어서 mean?

아파서 comes from 아프다 meaning to hurt / to be painful.

The ending -아서 / -어서 often means:

• because
• so
• sometimes just connects two actions smoothly

So 손목이 아파서 means because my wrist hurts or my wrist hurts, so...

In this sentence:

• 손목이 아파서 = because my wrist hurts
• 마우스를 오래 못 써요 = I can’t use the mouse for long

So the whole sentence is structured as:

[reason] + [result]

Korean very often puts the reason first.

Why is it 손목이 and not 내 손목이?

Korean often omits possessive words like my, your, or his/her when the owner is obvious from context, especially with:

• body parts
• family members
• personal belongings in clear situations

So 손목이 아파서 naturally means:

• because my wrist hurts

even though 내 is not stated.

If you say 내 손목이 아파서, it is still grammatically correct, but it can sound more explicit than necessary unless you want emphasis or contrast.
