For myself and the horse, brought out something to eat (7)
I believe the answer is:
pimento
'for' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?
'myself and the horse brought out something to eat' is the wordplay.
I cannot really see how this works, but
'myself' could be 'me' and 'me' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for pimento that I've seen before include "Something spicy" , "Vegetable" , "Sweet red pepper" , "Jamaica pepper" , "Allspice - top mine (anag)" .)
