Traducer → It is formed from "traducere" (Latin, meaning to lead across or to bring into disrepute) and the suffix "-er" (meaning a person who). A traducer is a person who leads someone into disrepute or slanders them.
Think of someone who 'leads' ('ducere') another's reputation 'across' ('tra-') to harm it — that's why a traducer is someone who slanders.
