Adult temptation said to subside (5)
I believe the answer is:
abate
'subside' is the definition.
(thesaurus)
'adult temptation said' is the wordplay.
'adult' becomes 'a'.
'temptation' becomes 'bait' (bait is a kind of temptation).
'said' shows a homophone (sound like).
'bait' is a homophone of 'bate'.
'a'+'bate'='ABATE'
'to' acts as a link.
(Other definitions for abate that I've seen before include "Lessen - cease" , "Put an end to" , "Become less in intensity" , "drop off" , "Go down like storm" .)
