Male in wild party gets treatment (7)
I believe the answer is:
therapy
'treatment' is the definition.
(I know that treatment can be written as therapy)
'male in wild party' is the wordplay.
'male' becomes 'he' (he refers to a man).
'in' means one lot of letters goes inside another.
'wild' indicates an anagram.
'party' is an anagram of 'trapy'.
'he' put into 'trapy' is 'THERAPY'.
'gets' is the link.
(Other definitions for therapy that I've seen before include "Healing treatment" , "will do you good" , "Curative treatment" , "Relieving treatment" , "Medical treatment" .)
