Etymology: "Renouncer" is about as plain as English word-building gets: it is the verb "renounce" with the agent suffix "-er" attached, so it means one who renounces. "Renounce" itself came into English from Old French "renoncer," which traces back to Latin "renuntiare," meaning to report back or announce, built from "re-" (back) and "nuntiare" (to announce). The sense of announcing something back gradually shifted toward formally giving something up, which is why a renouncer is someone who formally abandons a claim, a belief, a title or a way of life.
