Past Participle: detested
Detest is formed from "de-" (meaning down or away) and "testari" (meaning to witness or testify). The word originally conveys the sense of witnessing something negatively or with disdain, hence to dislike intensely or hate.
Think of 'witnessing' something 'down' or 'away' — that's why detest means to strongly dislike or hate.
