'Sarmatians' originates from the Latin word 'Sarmatae', which was derived from the Greek word 'Sarmatai', referring to the ancient people known for their nomadic lifestyle.

'Sarmatai' transformed into the Latin 'Sarmatae', and eventually became the modern English word 'Sarmatians'.

Initially, it referred to a specific group of ancient people, and this meaning has largely remained the same in modern usage.
