What a hen provides for a horse, in certain ways? (4)
I believe the answer is:
eggs
'what a hen provides' is the definition.
I can't tell whether this definition defines the answer.
'horse in certain ways?' is the wordplay.
'horse' becomes 'gg' (geegee or GG is a childish term for a horse).
'in' is an insertion indicator.
'certain ways?' becomes 'es' (east and south - two directions. I am not sure about the 'certain' bit.).
'gg' put within 'es' is 'EGGS'.
'for a' is the link.
Can you help me to learn more?
(Other definitions for eggs that I've seen before include "Ova" , "Roe" , "Bacon and - -" , "Poultry products" , "Bacon's partners" .)
