The term writer can apply to anyone who creates a written work, but the word more usually designates those who write creatively or professionally, or those who have written in many different forms. Skilled writers demonstrate skills in using language to portray ideas and images, whether producing fiction or non-fiction.
A writer may compose in many different forms, including (but not limited to): poetry, prose, music. Accordingly, a writer in specialist mode may rank as a poet, novelist, composer, lyricist, playwright, mythographer, journalist, film scriptwriter, etc. (See also: creative writing, technical writing and academic papers).
Writers' output frequently contributes to the cultural content of a society, and that society may value its writerly corpus -- or literature -- as an art much like the visual arts (see painting, sculpture, photography), music, craft and performance art (see: drama, theatre, opera, musical).
Alternative Uses of "Writer"
Practitioners within some specialized fields also use the term "writer" to describe their arts. For instance, advertising creatives, gag-writers and graffiti artists also refer to themselves as "writers." In these contexts, "writer" may be considered an alternative use of the term, rather than describing a so-called "literary" or "serious" writer as discussed above.
