The term 'whinny' is a sound made by horses and other equine animals. It can be described as a combination of four different sounds: BRAY (4 letters), NICKER (6 letters), NEIGH (5 letters), and SNORT (5 letters). A BRAY is a loud, harsh sound made by a donkey or mule. A NICKER is a soft, low sound made by a horse. A NEIGH is a loud, high-pitched sound made by a horse. Finally, a SNORT is a short, explosive sound made by a horse. Together, these four sounds make up the whinny of an equine animal.
