To publicly say that you no longer have, support, or believe in something.
From Old French *renoncier* “to give up, deny,” from Latin *renuntiare* “to announce back, report,” later “to announce against.” The idea shifted from reporting something to openly disowning it.
To renounce is to break up with something in public, not just in your head. The drama of the word shows how social identity and belief are often performances for an audience.
