What does eques mean?
An eques (plural equites) was a member of the equestrian order of ancient Rome, a privileged class of wealthy citizens positioned just below the senatorial elite. The name derives from the Latin for 'horseman,' reflecting the order's origins as Rome's cavalry. In the early Republic, equites were men rich enough to equip themselves with a horse for military service; over time the class evolved into a status defined by wealth rather than battlefield role, and under the emperors equites filled important posts in finance, administration, and provincial government. The word survives today only in scholarly and historical writing about Rome. It is the direct source of English words such as 'equestrian' and shares a root with 'equine,' making it a useful touchstone for understanding how deeply horses are woven into the vocabulary of rank, sport, and chivalry.
A member of the ancient Roman equestrian order, the wealthy citizen class ranking below senators that originated as the Republic's cavalry.
"An eques could hold public contracts and imperial offices without entering the Senate."
The standard plural is the Latin form 'equites.' The word is used almost exclusively in historical and classical scholarship.
A knight or horseman, especially in classical, heraldic, or literary usage.
"The tapestry depicted each eques bearing his family's colors."
This broader sense is rare and chiefly found in older or deliberately archaic prose.
The plural retains the Latin form and is pronounced /ˈɛkwɪtiːz/. It typically refers to the equestrian order collectively rather than to individual riders.
"The equites formed a powerful bloc in Roman commerce and finance."
The Latin word eques literally means 'horseman' — and it's the ancestor of both 'equestrian' and, surprisingly, 'equity', because Roman knights could serve as judges.

Etymology of eques
Eques comes directly from Latin, where it meant 'horseman' or 'rider' and derives from equus, the Latin word for horse. In Republican Rome it designated members of the equestrian order (equites), originally the cavalry-owning gentry. The root equ- spread into many modern terms via related forms, giving English 'equestrian,' 'equine,' and 'equitation,' while the figurative sense of a mounted warrior underlies 'equity' through the notion of fairness associated with the class's civic role.
How eques is actually used
"Eques" is a learned, scholarly term confined almost entirely to discussions of ancient Roman history and society; its plural is "equites." It appears rarely outside academic writing, where the anglicized phrase "Roman knight" is often preferred for general audiences.
