‘委员’ (wěi yuán) literally combines ‘委’ (wěi), meaning ‘to appoint’ or ‘to entrust’, and ‘员’ (yuán), meaning ‘member’ or ‘staff’. Together, it refers to a person officially appointed to serve on a committee — a formal group established to discuss, advise on, or make decisions about specific matters. It is a standard term used across government, education, business, and community organizations in Chinese-speaking contexts.

The word carries a formal, institutional tone and is rarely used in casual conversation unless referring to an actual role. ‘委员’ often appears as part of compound nouns like ‘政协委员’ (Chinese People’s Political Consultative Conference member) or ‘班委会委员’ (class committee member). Unlike generic terms for ‘member’ (e.g., 成员 chéngyuán), ‘委员’ implies delegation of responsibility and official standing within a structured body.
