Questions & Answers about kibodeuga gapjagi an dwaeseo mauseuroman munseoreul yeoreosseo.

Why is it 키보드가 and not 키보드를?

Because the keyboard is being presented as the thing that wasn’t working.

• 키보드가 안 되다 = the keyboard doesn’t work
• Here, 가 marks 키보드 as the subject of 안 되다

If you used 키보드를, that would make keyboard the object of another verb, which is not what is happening here. The sentence is not saying someone did something to the keyboard; it is saying the keyboard itself failed.

What does 안 돼서 mean here?

안 돼서 comes from 안 되다 + -아서/어서.

• 되다 can mean to work, to function, or to be possible, depending on context.
• 안 되다 here means to not work
• -아서/어서 connects clauses and often means because, so, or and then

So 키보드가 갑자기 안 돼서 means something like:

• because the keyboard suddenly stopped working
• the keyboard suddenly didn’t work, so...

In this sentence, it gives the reason for the next action.

Why is it 돼서 instead of 되어서?

돼서 is the contracted, very common spoken and written form of 되어서.

• 되다 → 되어 → 돼
• so 되어서 → 돼서

Both are correct, but 돼서 is much more natural in everyday Korean.
