abhor

I'm a little stuck... Click here to teach me more about this clue!

'hate' is the definition.
(abhorring is a kind of hating)

I cannot understand how the rest of the clue works.

(Other definitions for abhor that I've seen before include "Loathe, detest" , "can't stand" , "Dislike very much" , "Recoil from" , "Can't bear" .)

I've seen this clue in The Hindu.
