Bumpkin guarding Scottish port’s source of animal feed (7)
I believe the answer is:
hayrick
'source of animal feed' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'bumpkin guarding scottish port's' is the wordplay.
'bumpkin' becomes 'hick' (synonyms).
'guarding' means one lot of letters goes inside another (inserted letters are protected or guarded).
'scottish port' becomes 'ayr' (Ayr is a Scottish port town).
'hick' enclosing 'ayr' is 'HAYRICK'.
Can you help me to learn more?
(Another definition for hayrick that I've seen is " farmyard feature".)
