* Scientific classification: The scientific name for the domestic horse is Equus caballus. This is its binomial nomenclature, using genus and species.
* Common names: Horses have many common names depending on their breed, age, or use. For example, a young horse is a foal, a male horse is a stallion, and a female horse is a mare.
So, while "Equus caballus" is the scientific term for the species, there isn't a singular "scientific word" that encompasses all horses.
