Crime on the rise, flipping hard to get discipline (6)
I believe the answer is:
punish
'discipline' is the definition.
(thesaurus)
'crime on the rise flipping hard' is the wordplay.
'crime' becomes 'sin'.
'on' means one lot of letters go next to another.
'the rise' becomes 'up' (as a noun**).
'flipping' says the letters should be written in reverse.
'hard' becomes 'h'.
'sin'+'up'='sinup'
'sinup' in reverse letter order is 'punis'.
'punis'+'h'='PUNISH'
'to get' is the link.
(Other definitions for punish that I've seen before include "Like wordplay in speech" , "Fine perhaps" , "Treat harshly or severely" , "Chastise" , "beat" .)
