写作 (xiě zuò) is a noun meaning 'writing' as a skill, process, or academic activity—especially formal, creative, or expository writing. It combines 写 (xiě), meaning 'to write', and 作 (zuò), meaning 'to make' or 'work'; together, they convey the idea of 'making writing'—i.e., the act or product of composing text. Unlike the verb 写 (xiě) alone, 写作 emphasizes writing as a disciplined practice or field of study, not just the physical act of putting pen to paper.

This term appears frequently in educational contexts (e.g., writing courses, composition assignments), publishing, and literary discussion. It’s commonly used in phrases like 写作能力 (writing ability), 写作课 (writing class), and 创意写作 (creative writing). While it can refer to any kind of sustained written expression—including essays, stories, or reports—it rarely describes casual note-taking or texting, for which simpler terms like 写 or 打字 are preferred.
