Greene in adapting plot? (8)
I believe the answer is:
engineer
'plot?' is the definition.
(thesaurus)
'greene in adapting' is the wordplay.
'adapting' indicates anagramming the letters.
'greene'+'in'='greenein'
'greenein' anagrammed gives 'ENGINEER'.
(Other definitions for engineer that I've seen before include "plan" , "Professional who uses scientific knowledge to solve practical problems" , "Designer of machines etc" , "US or Canadian train driver" , "Arrange - contrive" .)
