writer

n. author; one who writes; copier, scribe

For the Word processor Writer, see: OpenOffice.org Writer. A writer is anyone who creates a written work, although the word more usually designates those who write creatively or professionally, or those who have written in many different forms. The word is almost synonymous with author, although somebody who writes, say, a laundry list, could technically be called the writer of the list, but not an author. Skilled writers are able to use language to portray ideas and images, whether producing fiction or non-fiction.
