侃言 (kǎn yán) literally combines 侃 (kǎn), meaning 'frank, unrestrained, or easygoing speech', and 言 (yán), meaning 'words' or 'speech'. Together, it refers to honest, straightforward, and unguarded words—spoken without pretense, flattery, or concealment. It conveys sincerity and moral courage in communication, often implying the speaker values truth over politeness or convenience.

This term is used more in written or formal spoken contexts—such as essays, speeches, or literary descriptions—rather than casual daily conversation. It carries a positive, respectful connotation, suggesting integrity and authenticity. While not archaic, 侃言 is somewhat literary and tends to appear when praising someone’s candidness, especially in ethical or intellectual discussions. It is distinct from colloquial terms like 直言 (zhí yán), which emphasizes bluntness more than moral earnestness.
