Usage
Where does the word horse come from? A horse is a horse, of course, of course. And that's basically true, etymologically speaking, too. Horse comes from the Old English hors. The word has many cousins in Germanic languages, and might come from an ancient root meaning "to run." If that’s the case—then of course!At the same time, that Old English hors has no relation to hors d'oeuvre, French for "outside the main course."And the word hoarse, meaning “having harsh or husky sound,” is a homonym of horse. While the words sound the same and are nearly spelled the same, they have different histories.

Etymology
Origin of horse
First recorded before 900; Middle English, Old English noun hors; cognate with Old Norse hross, Dutch ros, German Ross ( Middle High German ros, Old High German hros ), from Germanic horso-, perhaps from the same Proto-Indo-European root that is the source of Latin currere “to run” (from unattested cursere ); Middle English horsen “to provide with horses,” Old English horsian, derivative of the noun
Explanation
A horse is a large, four-legged animal with hooves, a long nose and tail, and a mane of hair along its upper back. Part of learning how to ride a horse includes giving commands and using the reins to guide it. Horses are very strong and fast, which is why humans have domesticated them for thousands of years — horses can be helpful on farms, for riding, and for pulling wagons and carts. Some people ride horses simply as a hobby, while others race them in competitions. Horses are one of the very few animals that can sleep either lying down or standing up, a trait that helped them run quickly from predators in the wild.
