劣迹 literally combines 劣 (liè), meaning 'poor', 'inferior', or 'bad', and 迹 (jì), meaning 'trace', 'track', or 'record'. Together, they form a noun meaning 'a record of misconduct' — typically referring to documented past behavior that is unethical, illegal, or otherwise socially unacceptable. It emphasizes the idea of observable, verifiable evidence of wrongdoing, not just rumors or suspicion.

This term is commonly used in formal or semi-formal contexts — especially in media reports, official investigations, personnel evaluations, or public accountability discussions. It often appears with verbs like 有 (yǒu, 'to have'), 揭露 (jiēlù, 'to expose'), or 留下 (liú xià, 'to leave behind'). While it can apply to individuals in any field, it’s frequently seen in discussions about public figures, celebrities, civil servants, or medical professionals whose actions have violated professional or legal standards.
