She put a checkmark next to the tasks she had completed.
Checkmark → The word is formed from "check" (from Old French *eschequier*, meaning to inspect or verify) and "mark" (from Old English *mearc*, meaning a sign or symbol). A checkmark signifies that something has been verified or marked as correct.
Think of 'checking' something to verify it and then 'marking' it as correct — that's why a checkmark indicates something has been confirmed.
