Some misdemeanour is hard to encourage (7)
I believe the answer is:
nourish
'encourage' is the definition.
(I've seen this before)
'some misdemeanour is hard' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'NOURISH' can be found hidden inside 'misdemeanour is hard'.
'to' is the link.
(Other definitions for nourish that I've seen before include "Give sustenance to" , "Provide with materials for life and growth" , "Supply with food, keep well" , "Nurture, sustain" , "Provide with food for growth" .)
