Monkey one for seafood treat (6)
I believe the answer is:
scampi
'seafood treat' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'monkey one' is the wordplay.
'monkey' becomes 'scamp' (both can mean a mischievous child).
'one' becomes 'I' (Roman numeral).
'scamp'+'i'='SCAMPI'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for scampi that I've seen before include "Fish dish, often in rings" , "Dish of deep-friend prawns" , "Shellfish" , "Breaded prawns" , "Dish of fried shrimp or prawns" .)
