Start being a complete lunatic re pumpkin (9)
I believe the answer is:
butternut
're pumpkin' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'start being a complete lunatic' is the wordplay.
'start being' becomes 'b' (I can't explain this - if you can you should give a lot more credence to this answer).
'a complete' becomes 'utter' (both can mean total).
'lunatic' becomes 'nut' (I've seen this before).
'b'+'utter'+'nut'='BUTTERNUT'
Can you help me to learn more?
(Other definitions for butternut that I've seen before include "species of tree" , "Variety of pumpkin" , "Wood" , "sort of a squash" .)
