Coauthor
/ˌkoʊˈɔː.θər/noun
A person who writes a work together with another author.
Did you know?The prefix co- comes from Latin *com-* meaning “with, together,” so a coauthor is literally someone who authors a work *with* another person, not a mystical title but a very old grammar of collaboration.
