Breakfast for one - guests cleared out (4)
I believe the answer is:
eggs
'breakfast' 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?
'for one guests cleared out' is the wordplay.
'for one' becomes 'eg' (I've seen this in other clues**).
'cleared out' suggests removing the centre.
'guests' with its middle taken out is 'gs'.
'eg'+'gs'='EGGS'
Can you help me to learn more?
(Other definitions for eggs that I've seen before include "Poultry products" , "Easter treats!" , "Don't put all these in one basket" , "Don't teach your grandmother to suck --" , "Roe" .)
