Dissenting voters reportedly making beastly noises (6)
I believe the answer is:
'noises' is the definition.
The answer and definition can be both related to natural events as well as being plural nouns.
Maybe there's a link between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for neighs that I've seen before include "Makes whinnying sound like horse" , "beastly sounds" , "Makes noise like horse" , "Sounds made by a horse" , "Makes noises like a horse" .)
