成员
chéngyuán · HSK 3
member
👥 成 = become/complete + 员 = person in a role → member
成 means to become or form, and 员 denotes a person filling a role (also in 职员 staff, 演员 actor). Together: someone who has become part of a group — a member.
成 — 戊 (halberd/weapon) + 丁 (nail/man)
Originally a pictograph of a halberd or axe-like weapon, suggesting the act of completing a task by force. Over time it shifted from 'to subdue' to the broader meaning 'to accomplish' or 'to become'. The 丁 element inside also hints at the chéng sound.
员 — mouth 口 + shell/money 贝 (貝)
Originally a pictograph of a round bronze tripod vessel, with 口 depicting its round opening and 鼎 (later simplified to 貝/贝) showing the vessel itself. The original sense was 'round,' now written 圓/圆. It was borrowed to mean 'member' or 'person in a role,' which became its main modern meaning.
