“Fast” can mean “speedy” or “held secure.” The word “clip” can mean “to attach something” or “to cut it off.” “To continue” means “to persist in doing something,” except in legal settings, where it means “to stop a proceeding temporarily.” A contranym is a word with two opposite meanings — the term was coined in the 1960s, based on the construction of “synonym” and “antonym,” but with “contra,” or Latin for “against.”
