‘司职’ is a formal verb meaning ‘to hold office’ or ‘to be in charge of duties,’ especially in official, organizational, or institutional contexts. The character 司 (sī) originally meant ‘to manage’ or ‘to oversee,’ and 职 (zhí) means ‘duty,’ ‘post,’ or ‘office.’ Together, they emphasize the act of formally assuming and carrying out responsibilities tied to a specific position—often in government, education, sports teams, or corporate settings. It implies authority, accountability, and defined scope of work.

This term is commonly used in written Chinese and formal speech—not in casual conversation—and frequently appears in news reports, official announcements, or biographical profiles. It often follows subjects like people’s names or titles (e.g., ‘张教授’), and can be modified by adverbs like ‘长期’ (long-term) or ‘现任’ (current). Unlike more general verbs like ‘负责’ (fùzé, ‘to be responsible for’), ‘司职’ carries connotations of legitimacy, appointment, and structural role within an organization.
