The history of the word "abhor"
begins in late Middle English, borrowed from the Latin verb abhorrēre, which means "to recoil from" or "to shudder at". It is a combination of the prefix ab- ("from, away") and the verb horrēre ("to bristle, shiver, or shudder"). This etymology explains the word's meaning of intense disgust and its relationship to words like "horror".

Latin roots: Abhorrēre is a compound of ab- ("from, away") and horrēre ("to bristle, shiver, or shudder").
