Abhor implies strong feelings of repugnance, disgust, and aversion. This degree of distaste is seen in the word's history. In earlier use, abhor sometimes implied an actual shrinking away from something in horror or repugnance. Appropriately, the word's Latin source, the verb abhorrēre, comes from the prefix ab- ("from, away") and the verb horrēre ("to bristle, shiver, or shudder"). As you may have guessed, the Latin horrēre is also the source of the English words horror, horrify, and horrible.

The Horror in Abhor

Abhor means “to loathe” or “to hate,” and while loathe and hate have roots in Old English, abhor derives from Latin. The roots of abhor can give us a deeper understanding of both the strength of the dislike expressed by the word and its relationship to other words in English. It came from the Latin word abhorrēre, which meant “to recoil from” or “to be repugnant to,” and was formed by combining ab-, meaning “from” and horrēre, meaning “to bristle,” “to tremble,” or “to shudder.” This word for trembling or shuddering in reaction to something scary or awful is related to the word that names of the cause of those reactions—the Latin word horror, which was later borrowed into English. The -hor of abhor is also the hor- of horror.
