Produce electricity from teenager? (8)
I believe the answer is:
generate
'produce electricity' is the definition.
(synonyms)
'from teenager?' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'teenager' anagrammed gives 'GENERATE'.
(Other definitions for generate that I've seen before include "Make" , "Produce - teenager (anag)" , "Produce (energy, etc)" , "Produce with green tea" , "Give rise to" .)
