Have an aversion to violent crime by men (5)
I believe the answer is:
abhor
'have' is the definition.
Although both the answer and definition are verbs in their base form, I can't see how one could define the other.
'an aversion to violent crime by men' is the wordplay.
I cannot really see how this works, but
'an' could be 'a' and 'a' is present in the answer.
'men' could be 'or' (I've seen this in other clues) and 'or' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for abhor that I've seen before include "can't stand" , "Regard with disgust and hatred" , "Dislike very much" , "Reject" , "Execrate" .)
