One bringing meat to feed animals (9)
I believe the answer is:
deliverer
'one bringing' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'meat to feed animals' is the wordplay.
'meat' becomes 'liver' (liver is a kind of meat).
'to feed' means one lot of letters goes inside another (one word is fed by another set of letters).
'animals' becomes 'deer' (type of animals).
'liver' inserted within 'deer' is 'DELIVERER'.
Can you help me to learn more?
(Another definition for deliverer that I've seen is " Saviour".)
