くせに

くせに expresses a complaint or reproach about someone’s behavior that is inconsistent with what they have done, said, or are in a position to do. It often carries a sense of ‘for all that’ or ‘despite being X, you Y’ and can sound critical or irritated. It’s used when the speaker expects better consistency or is annoyed by a contradiction. Notes: - It attaches to the plain form: to verbs, i-adjectives, na-adjectives (with な), and nouns (with の). - It tends to imply the speaker’s disapproval or sarcasm. - Often used in conversations or written remarks where someone is lamenting a double standard or inconsistency. Examples: - 彼は約束をすると言ったくせに、結局守らなかった。 (Even though he said he would keep the promise, he didn’t in the end.) - 彼女は若いくせに、もう大人のように振る舞う。 (She’s young, yet she behaves like an adult.) - 学校に行くくせに、宿題をしない。 (Even though he goes to school, he doesn’t do homework.) - 大人のくせに、そんなことで怒るの？ (For an adult, you’re getting angry about something like that?) - 子どものくせに、そんなに夜更かしをする。 (Despite being a child, you stay up so late.)
