Expression of the Week

다 제 탓입니다 (it’s all my fault)

다 – all, entirely

제 – form of abbreviation for “저의” meaning “my”

탓 – reason, fault or blame 

Casual – 다 내 탓이야

Semi-polite – 다 내 탓이에요

Polite – 다 제 탓입니다 

>>[제] is an abbreviated form of “저의” and makes the expression polite because “저” is the self-lowering form of “나” (I), which is used by the speaker to show humility.

>>[내 탓이다] means the blame is on me, or it is my fault.

>>However, the verb [탓하다] means to lay blame on for find fault with someone or something else.
