A better supplier of eggs (5)
I believe the answer is:
layer
This clue could be a double definition.
'a better supplier' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'eggs' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'of' is the link.
Can you help me to learn more?
(Other definitions for layer that I've seen before include "Stratum or thickness" , "Productive chicken" , "Hen, perhaps" , "Tier or thickness - or a hen?" , "Thin sheet - productive hen" .)
