Root Explanation
Coauthor → It is formed from "co-" (meaning together) and "author" (from Latin "auctor", meaning creator or originator). The word "coauthor" means someone who creates or writes together with another person.
Memory Tip
Think of two people creating something "together" ('co-') as an "originator" ('author') — that's what a coauthor does.
