Donkey's cry (4)
I believe the answer is:
bray
'donkey's cry' 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 "Neigh" , "Cry like a donkey" , "Sound like a donkey in Wicklow" , "Berkshire village with a 16th-century vicar celebrated in legend and song" , "Proclaim loudly" .)
