Measure growth as part of consumption (6)
I believe the answer is:
entree
'part of consumption' is the definition.
'entree' can be an answer for 'part' (I have seen 'part of meal' mean 'entree' so perhaps 'part' could also mean 'entree'). I'm unsure of the 'of consumption' bit.
'measure growth' is the wordplay.
'measure' becomes 'en' (typographical measure).
'growth' becomes 'tree' (I have seen 'Large growth ' mean 'tree' so perhaps 'growth' could also mean 'tree').
'en'+'tree'='ENTREE'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for entree that I've seen before include "No way-out" , "The right to go in to the dish" , "Principal dish and right to enter" , "Dish served between fish and meat course" , "Something that provides access" .)
