'作者' (zuò zhě) literally combines '作' (zuò), meaning 'to create, to write, or to compose', and '者' (zhě), a classical suffix meaning 'person who does something'. Together, they form a formal noun meaning 'author' — the person who originates or writes a literary, academic, or creative work. It is commonly used in publishing, education, and copyright contexts, and appears frequently in book covers, citations, and academic papers.

Unlike more colloquial terms like '写手' (xiěshǒu, 'writer') or '作家' (zuòjiā, 'professional writer'), '作者' emphasizes authorship and intellectual ownership rather than profession or style. It can refer to anyone credited for creating original written content — whether a novelist, researcher, blogger, or student submitting an essay. The term is neutral in register but leans slightly formal; it rarely appears in casual speech unless discussing attribution or sources.
