Donkey:  Common English term for asses. It's derivation is related to the older English words dun referring to its color, and ky a diminutive meaning small. Since most donkeys are pony-sized, the animal became known as the dunky, the small dun colored animal. Even today, the largest number of English donkeys will be the typical "grey-dun" (slate) color with dorsal stripe and cross. British nicknames for donkeys are " Moke" and " Neddy".

Burro: This is a common name for the small donkey located in the Southwestern portion of the United States. It is the Spanish equivalent to the term "donkey". It is the name of the everyday working animal.  The Spanish have a large vocabulary for asses, with several terms for a breeding herd, breeding jack, breeding jennet, mule breeding stock, etc. However, when talking about the animal carrying water jars down the street, he is a burro. This term has come into common use in the Western part of the United States. Burro, however is not considered a proper term to use when referring to large Jackstock or to the Miniature Mediterranean donkey.

Hinny: A hybrid produced with the donkey jennet as the mother and the stallion horse as the father. Some hinnies are indistinguishable from mules, others look quite a bit more horse.  The voices of both the mule and hinny vary considerably from animal to animal and are quite different from the bray of an ass and the whinny of the horse. They are usually an interesting combination of the two and each animal has its own vocal style. ​​​​​​​​

Bray: The "hee-haw" sound made by the ass. It is made by a sort of bellow action of the chest and belly.
