verb
renounce
rih-NOUNSS/rɪˈnaʊns/
To formally give up or reject something.
The official renounces the former allegiance by laying down the badge.

Etymology
“Against” plus “announce” connects renouncing with declaring opposition. The Latin verb already meant “protest against” or “renounce,” helping explain the English sense of formally giving up a belief, allegiance, or claim.
