Questions & Answers about pyegimul ttaemune baesuguga makhyeossseupnida.

What does 때문에 mean here?

때문에 means because of or due to.

So 폐기물 때문에 means because of the waste or due to waste.

A useful pattern is:

• noun + 때문에 = because of the noun
• verb/adjective stem + 기 때문에 = because/because of the fact that ...

Examples:

• 비 때문에 = because of the rain
• 비가 오기 때문에 = because it is raining

In your sentence, 폐기물 is a noun, so 때문에 attaches directly to it.

Why is 배수구 marked with 가?

Because 배수구가 is the subject of 막혔습니다.

The verb here is 막히다, which means to be blocked / to get clogged. With this verb, the thing that becomes blocked is marked with 이/가.

So:

• 배수구가 막혔습니다 = the drain got clogged / the drain is clogged

Even though English might focus on waste as the cause, Korean grammar treats the drain as the thing in the blocked state, so 가 is natural here.

What is the dictionary form of 막혔습니다?

The dictionary form is 막히다.

Breakdown:

• 막히다 = to be blocked, to get clogged
• 막혔- = past tense stem
• 습니다 = formal polite ending

So 막혔습니다 means was blocked, got blocked, or has become blocked, depending on context.
