Carefree? Let in some Scottish stock! (8)
I believe the answer is:
galloway
'some scottish stock' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'carefree? let in' is the wordplay.
'carefree?' becomes 'gay' (I've seen this in another clue).
'let' becomes 'allow' (synonyms).
'in' indicates putting letters inside.
'gay' going around 'allow' is 'GALLOWAY'.
Can you help me to learn more?
(Other definitions for galloway that I've seen before include "Breed of cattle; area of Scotland" , "Scots breed of cattle" , "Scottish region" , "Respect MP" , "farm animal" .)
