Revile man cooking pies (7)
I believe the answer is:
despise
'revile' 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.
'man cooking pies' is the wordplay.
'man' becomes 'des' ().
'cooking' is an anagram indicator (cook can mean to falsify or distort).
'pies' is an anagram of 'pise'.
'des'+'pise'='DESPISE'
Can you help me to learn more?
(Other definitions for despise that I've seen before include "Hold in contempt" , "Feel contempt for; scorn" , "Hate, disdain" , "Loathe, look down on" , "Look down on with disdain" .)
