Food may start to nourish in the large intestine (9)
I believe the answer is:
colcannon
'food' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?
'may start to nourish in the large intestine' is the wordplay.
'may' becomes 'can' (synonyms).
'start to' says to take the initial letters.
'in the' means one lot of letters goes inside another.
'large intestine' becomes 'colon' (colon is a kind of large intestine).
The first letter of 'nourish' is 'n'.
'can'+'n'='cann'
'cann' going inside 'colon' is 'COLCANNON'.
Can you help me to learn more?
(Other definitions for colcannon that I've seen before include "Irish cabbage, potato dish" , "Vegetarian dish for 19 [PADRAIC]" , "Food for Irish" , "fed to the Irish?" , "Traditional Irish dish of mashed potatoes and cabbage" .)
