Revoker → It is formed from "re-" (meaning again) and "vocare" (meaning to call). The word "revoker" refers to someone who calls back or withdraws something, such as a decision or an offer.
Think of someone 'calling back' ('vocare') something 'again' ('re-') — that's why a revoker is someone who withdraws or cancels something.
