Our neighbours drink for breakfast (6,5)
I believe the answer is:
french toast
'breakfast' is the definition.
(I know that French toast is a breakfast)
'our neighbours drink' is the wordplay.
'our neighbours' becomes 'french' (I can't explain this - if you can you should believe this answer much more).
'drink' becomes 'toast' (toast is a kind of drink).
'french'+'toast'='FRENCH TOAST'
'for' is the link.
Can you help me to learn more?
(Other definitions for french toast that I've seen before include "Bread fried with egg and milk" , "fried breakfast?" .)
