Source of protein to feed country creature (8)
I believe the answer is:
terrapin
'creature' is the definition.
The definition and answer can be both animals as well as being singular nouns.
I also know that 'creature' relates to this answer.
'source of protein to feed country' is the wordplay.
'source of' says to take the initial letters (the start - or source - of the word).
'to feed' indicates putting letters inside (one word is fed into another).
'country' becomes 'terrain' (terrain means some land or country).
The first letter of 'protein' is 'p'.
'p' going inside 'terrain' is 'TERRAPIN'.
Can you help me to learn more?
(Other definitions for terrapin that I've seen before include "Little turtle" , "Chelonian reptile" , "Aquatic tortoise" , "Hardback" , "freshwater creature" .)
