"Donkey" and "burro" are two words that refer to the same animal. "Donkey" is used to refer to the domesticated version, and "burro" is used to refer to smaller donkeys or wild donkeys most commonly found in the West.
"Burro" is the Spanish word for "donkey." It has been borrowed and used in English to differentiate between domesticated and wild donkeys. Working donkeys are associated with areas with low incomes, while pet and breeding donkeys are found in developed countries.
A male donkey is called a "jack," and a female donkey is called a "jenny." A young donkey is known as a "foal." Another commonly used word for donkey is "ass."
