Breakfast urges (4)
I believe the answer is:
eggs
This clue could be a double definition.
'breakfast' is the first 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?
'urges' is the second definition.
(to egg someone on is to urge them to do something)
Can you help me to learn more?
(Other definitions for eggs that I've seen before include "Ovoid objects" , "Bombs or mines (slang)" , "Incites - farm produce" , "Reproductive cells" , "Contents of nests" .)
