In the Spanish language, “caballero” means “gentleman,” and the word is still used as such for men who value gentlemanly principles of chivalry, treating people with respect, displaying integrity and honesty, and using proper manners in all situations. A caballero will be at ease in any social situation, from a casual afternoon barbecue to a formal gala. The word was adopted in the southwestern U.S. in the mid-19th century to specifically refer to a horseman. It makes sense then that the Latin root word for “caballero” is “caballus,” which means “horse.”
