Meaning

A conjunction expressing the speaker's contempt, frustration, or criticism about someone's contradictory behaviour. Equivalent to 'even though' or 'despite' with a negative, accusatory nuance.

くせに is a concessive conjunction that carries strong negative emotion — typically contempt, irritation, or blame. Unlike のに, which can express neutral or sympathetic surprise, くせに always conveys that the speaker finds the contradiction objectionable. It is almost exclusively used to criticise others, and using it about oneself sounds unnatural unless expressing self-deprecation. Because of its confrontational tone, it should be avoided in formal or polite contexts. The pattern connects to verbs and adjectives in their plain forms, and to nouns via の.

Examples

  1. 自分は料理ができないくせに、人の作った料理に文句ばかり言う。 Even though he can't cook himself, he only complains about other people's food.
  2. 何も知らないくせに、偉そうなことを言わないでほしい。 I wish he wouldn't act so high and mighty when he doesn't know anything.
  3. 約束を守らないくせに、他人には厳しく当たる。 Even though he never keeps his promises, he's hard on others.
