Produce awkward teenager (8)
I believe the answer is:
generate
'produce' is the definition.
(I know that generate is a more specific form of produce)
'awkward teenager' is the wordplay.
'awkward' indicates anagramming the letters.
'teenager' with letters rearranged gives 'GENERATE'.
(Other definitions for generate that I've seen before include "available in form" , "Bring into existence for teenager" , "Give rise to" , "Produce, electricity say" , "Engender" .)
