Neighsayer? (5)

I believe the answer is:

horse

'neighsayer?' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for horse that I've seen before include "runner" , "drug?" , "Vaulting --; -- sense" , "Animal featuring in the sport of kings" , "Eg, mare" .)

I've seen this clue in The Sun.
