Urge farm produce (3)
I believe the answer is:
egg
This clue could be a double definition.
'urge' is the first definition.
(as in egging someone on)
'farm produce' is the second definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for egg that I've seen before include "Yolk and white in a shell" , "Poached or boiled?" , "Reproductive cell" , "explosive" , "Curate's good in parts" .)
