Push in so as to hurt (6)
I believe the answer is:
punish
'to hurt' is the definition.
(thesaurus)
'push in so' is the wordplay.
'push in' anagrams to 'PUNISH'.
Though, I'm unsure how the anagram is indicated.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for punish that I've seen before include "Possibly fine" , "exact retribution" , "Like wordplay in speech" , "Impose penalty for crime or misbehaviour" , "Castigate" .)
