Donkey sound (4)
I believe the answer is:
bray
'donkey sound' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bray that I've seen before include "Cry of animal" , "Proclaim loudly" , "where musical vicar lived" , "Harsh cry" , "renegade vicar's place" .)
