Pair trained Manx cat, a divine male (7)
I believe the answer is:
priapus
'a divine male' is the definition.
(Greek god)
'pair trained manx cat' is the wordplay.
'trained' is an anagram indicator (train can mean to shape or manipulate).
'manx' means to remove the last letter (Manx cats have no tail).
'cat' becomes 'puss' (puss is a kind of cat).
'puss' with its final letter taken away is 'pus'.
'pair' anagrammed gives 'pria'.
'pria'+'pus'='PRIAPUS'
(Other definitions for priapus that I've seen before include "Sex god" , "garden guardian" .)
