because of 때문

N + 때문 V/Adj + 기 때문 It means ‘because of~’. It's not a marker, still it’s often used after a noun, functioning like a marker. Use ‘때문에’ when you want to continue the sentence with another clause, and use ‘때문이다’ when you want to end the sentence.

비 때문에 소풍이 취소되었어요.

Because of the rain, the picnic was canceled.

벌레 때문에 문을 닫았어요.

I closed the door because of the bugs.

A: 수지 씨가 왜 화가 났어요? Why is Suzy upset?

• You can use it with verbs in the form of 'Verb Root+기 때문에/기 때문이다'.

요즘 너무 춥기 때문에 감기에 걸렸어요.

I caught a cold because it's been too cold lately.

(The meaning is similar to the connective ending ‘-어서’, but it sounds more formal and book(written) style than -어서, and it emphasizes the reason more strongly.)

남자친구랑 싸웠기 때문이에요.

It's because she fought with her boyfriend.
