You won't like anybody getting yours! (4)
I believe the answer is:
goat
'you' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for goat that I've seen before include "lecherous sort" , "Animal in zodiac" , "Domesticated animal supplying milk, meat and wool" , "lecher" , "Butting nanny, perhaps?" .)
