Unclaimed → It is formed from "un-" (meaning not) and "claimed" (from Old French *clamer*, meaning to call out or declare). The word "unclaimed" means not called out for or not declared as belonging to someone.
Think of something that is 'not' ('un-') 'called out' or 'declared' ('claimed') — that's why unclaimed refers to something that has not been claimed.
