聪明 (cōng míng) is an adjective meaning 'intelligent' or 'clever,' describing someone who learns quickly, understands easily, and solves problems well. The character 聪 (cōng) originally refers to acute hearing—symbolizing the ability to perceive and absorb information—and 明 (míng) means 'bright' or 'clear,' representing mental clarity and insight. Together, they evoke a person whose mind is both perceptive and lucid.

This word is commonly used to praise children’s quick learning, students’ academic aptitude, or colleagues’ sharp reasoning. It carries a warm, positive connotation and is often heard in everyday praise (e.g., '你真聪明!') rather than formal assessments. While it can describe innate ability, it’s also frequently associated with active curiosity and responsiveness—not just high IQ. It’s rarely used for inanimate objects or abstract concepts; it almost always modifies people or their behavior.
