'antelope' originates from Middle English, specifically the word 'antelop,' which was derived from Old French 'antelop,' and further from Medieval Latin 'ant(h)alopus,' which was borrowed from Byzantine Greek 'antholops,' referring to a mythical creature.

'antelope' changed from the Old French word 'antelop' and eventually became the modern English word 'antelope'.

Initially, it referred to a mythical creature, but over time it evolved into its current meaning of a swift, horned animal.
