Nonactor → It is formed from "non-" (meaning not) and "actor" (from Latin "actor", meaning one who does or performs). The word "nonactor" refers to someone who does not perform or is not an actor.
Think of 'non-' meaning 'not' and 'actor' meaning 'one who performs' — so a nonactor is someone who does not perform.
