作家 (zuò jiā) literally combines 作 (zuò), meaning 'to create' or 'to write', and 家 (jiā), meaning 'expert' or 'specialist'. Together, they form a noun meaning 'writer' — specifically someone who professionally creates literary works such as novels, short stories, essays, or poetry. Unlike the more general term 作者 (zuò zhě), which simply means 'author' (anyone who writes something), 作家 carries a connotation of artistic skill, professional identity, and recognized contribution to literature.

This word is commonly used in formal and informal contexts — for example, when introducing a speaker at a literary event, describing someone’s occupation, or discussing cultural figures. It can refer to both living and deceased writers, and appears frequently in media, education, and publishing. While not limited by genre, it typically implies creative writing rather than technical, journalistic, or academic writing alone — though acclaimed journalists or scholars who publish widely in literary styles may also be called 作家.
