Stop being inspired by fresh green produce (8)
I believe the answer is:
engender
'produce' is the definition.
(I've seen this in another clue)
'stop being inspired by fresh green' is the wordplay.
'stop' becomes 'end' (synonyms).
'being inspired by' is an insertion indicator (some letters breathed in or 'inspired' by others).
'fresh' indicates an anagram.
'green' anagrammed gives 'enger'.
'end' put within 'enger' is 'ENGENDER'.
(Other definitions for engender that I've seen before include "Father" , "Give rise to; beget" , "Generate - green den (anag)" , "Give rise to, cause" , "Bring forth" .)
