果断 (guǒ duàn) is an adjective meaning 'decisive' or 'resolute'—describing someone who makes clear, firm decisions quickly and confidently, without hesitation or doubt. The first character 果 (guǒ) originally means 'fruit', but here it carries the sense of 'result' or 'consequence', implying an outcome that follows directly from action. The second character 断 (duàn) means 'to cut off' or 'to decide', suggesting the act of cutting away uncertainty or indecision. Together, they evoke the image of decisively severing doubt to arrive at a firm conclusion.

This word is commonly used to praise leadership qualities, personal character, or effective problem-solving—especially in contexts involving responsibility, crisis response, or professional judgment. It carries a positive, commendatory tone and often appears in formal writing, performance reviews, or motivational speech. While it describes a trait, it’s rarely used as a noun on its own; instead, it modifies nouns (e.g., 果断的决定, 'a decisive decision') or functions predicatively (e.g., 他很果断, 'He is decisive').
