Put off, in crude terms (5)
I believe the answer is:
deter
'put off' is the definition.
(thesaurus)
'in crude terms' is the wordplay.
'in' indicates the answer is hidden within the clue.
'DETER' is hidden within 'crude terms'.
(Other definitions for deter that I've seen before include "Inhibit" , "Discourage, put off" , "Put off (from an action)" , "Discourage (someone from an action)" , "stop" .)
