Push in, perhaps, and hurt (6)
I believe the answer is:
punish
'hurt' is the definition.
(thesaurus)
'push in perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'push'+'in'='pushin'
'pushin' with letters rearranged gives 'PUNISH'.
'and' acts as a link.
(Other definitions for punish that I've seen before include "Possibly fine" , "Like wordplay in speech" , "Mete out penalty to" , "Impose penalty for crime or misbehaviour" , "Penalise" .)
