明朗 (míng lǎng) is an adjective meaning 'clear and distinct'—as in a bright sky, a lucid explanation, or well-defined features—and also 'optimistic' or 'upbeat', especially when describing someone's mood or outlook on life. The character 明 means 'bright' or 'clear', evoking light and transparency; 朗 means 'loud', 'clear', or 'bright', reinforcing clarity and openness. Together, they form a compound that emphasizes both perceptual clarity (e.g., weather, speech, logic) and emotional positivity (e.g., attitude, expectations).

This word is commonly used in formal and semi-formal contexts: in news reports describing weather or policy, in literature depicting characters’ dispositions, or in everyday speech to praise someone’s cheerful, confident demeanor. It carries a positive, often uplifting connotation and rarely appears in negative constructions. While it can describe physical conditions (e.g., a clear day), its emotional sense is equally frequent and idiomatic—especially in phrases like '态度明朗' (a clear/decisive attitude) or '心情明朗' (an optimistic mood).
