有罪(yǒu zuì) - guilty, culpable in Mandarin

有罪 (yǒu zuì) is the verdict word. A court reaches it, a jury returns it, and once it lands the sentencing follows. Its opposite is not 不有罪, which no one says, but 无罪, not guilty, and the pair is worth learning together because you will hear them announced in the same breath.

Outside the courtroom it stretches to moral guilt, but it stays heavy. 他心里觉得自己有罪 is a man who believes he has genuinely done wrong, not one who is mildly embarrassed. The everyday register keeps 有 in front of it: 判他有罪, 认为她有罪, 承认自己有罪.

The trap is that English "guilty" does double duty and Mandarin does not. "I feel guilty about forgetting your birthday" is not 我有罪, which sounds like a confession to a crime. Reach for 内疚 or 过意不去 instead, and keep 有罪 for the times when there really is a charge to answer.
