a person who is able to write and has written something
"The local library hired a writer to compile stories about the town's history for their new annual anthology."
A person who writes, or produces literary work.
"The local writer spent all weekend revising her novel before submitting it to the publisher."
In plain English: A writer is someone who creates stories, articles, or other texts by putting words down on paper or into a computer.
"The famous writer spent the whole afternoon in his study finishing his new novel."
Usage: Use writer to refer specifically to an author of books, articles, or other texts rather than someone who simply composes notes. Do not confuse this role with editor, as a writer creates the original content while an editor refines it.
The word "writer" comes from Middle English and Old English, where it originally described a scribe, painter, or composer of texts. It entered modern English by combining the verb "write" with the suffix "-er" to denote someone who performs that action.
