‘廉洁’ (lián jié) literally combines ‘廉’ (lián), meaning ‘honest,’ ‘upright,’ or ‘not greedy,’ and ‘洁’ (jié), meaning ‘clean,’ ‘pure,’ or ‘uncontaminated.’ Together, they form a compound expressing moral purity—specifically, integrity and honesty in conduct, especially in positions of power or public service. It emphasizes freedom from corruption, bribery, or personal gain at the expense of duty.

This term is frequently used in formal, political, or institutional contexts—for example, in anti-corruption campaigns, civil service ethics training, or official speeches about governance. While it can describe individuals (e.g., a clean official), it more often functions as an abstract ideal or standard to uphold. Unlike casual synonyms like ‘诚实’ (honesty in everyday truth-telling), ‘廉洁’ carries strong connotations of ethical discipline in roles involving authority, resources, or public trust.
