Etymology

The word "co-author" combines the prefix "co-" (from Latin "com-," meaning "together") with "author" (from Latin "auctor," meaning "originator" or "creator"). The prefix "co-" emphasizes collaboration, while "author" retains its core meaning of a writer or creator. This construction logically reflects the joint effort in producing written work.
