ἱπποκένταυρος

Etymology
From. While "horse centaur" may seem redundant, it should be noted that originally referred to a race of people, the Centaurs, who are associated in some myths with the origin of the creature "centaur". This term likely made the distinction between a person of the Centaur race and the creature, until later, when the word simply referred to the creature. Note that while Wiktionary distinguishes between upper and lower case in Ancient Greek words, Ancient Greek did not (minuscules were not invented until the seventh century).

Noun
