实用 (shí yòng) is an adjective meaning 'practical' or 'functional'—describing something that serves a real, useful purpose rather than being decorative, theoretical, or overly complex. The first character 实 (shí) means 'real', 'actual', or 'substantial', while 用 (yòng) means 'to use' or 'function'. Together, they literally convey 'real use' — emphasizing tangible utility and everyday applicability.

This word commonly modifies nouns like 工具 (tools), 方法 (methods), 建议 (advice), or 设计 (design), especially in contexts related to daily life, technology, education, or problem-solving. It carries a positive, down-to-earth connotation — praising efficiency and relevance over formality or elegance. Unlike 美观 (aesthetic) or 理论 (theoretical), 实用 highlights concrete value and usability for ordinary people.
