If only some writers would quit violating the definitions of copyright and copywrite!

Copyright refers to the exclusive legal right to use artistic material. Its forms can serve as a noun (I own the copyright to my novel.), an adjective (copyrighted material), or verb (You should copyright your manuscript.).

Copywrite isn’t a word. Copywriter and copywriting are, however, and they refer to someone who pens text for a living. They typically are used as nouns (The English major’s first job out of college was as a copywriter or The English major’s first job out of college was in copywriting).
