修辞 (xiū cí) literally means 'to cultivate language'—'修' (xiū) conveys refinement or improvement, while '辞' (cí) refers to words, speech, or expression. Together, the term denotes the art and techniques of effective, persuasive, or aesthetically pleasing language use—what English calls 'rhetoric' or 'figurative language.' It includes devices like metaphor, parallelism, repetition, personification, and rhetorical questions.

In Chinese education and writing, 修辞 is a core concept taught from middle school onward. It appears in literary analysis, essay composition, public speaking, and even everyday communication when speakers intentionally shape language for emphasis, elegance, or emotional impact. Unlike general vocabulary study, 修辞 focuses on *how* language functions stylistically—not just what words mean, but how their arrangement and choice affect meaning and reception.
