Food to fight for? (4)
I believe the answer is:
buns
'for?' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'food to fight' is the wordplay.
'food' becomes 'bun' (bun is a kind of food).
'to fight' becomes 's' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'bun'+'s'='BUNS'
Can you help me to learn more?
(Other definitions for buns that I've seen before include "Small rolls" , "Cakes" , "Food items" .)
