What languages were spoken by Aristotle?

Aristotle, being a Greek philosopher, primarily spoke Ancient Greek. This was the dominant language of his time and place, and the language in which he wrote his extensive philosophical and scientific works.

It's highly unlikely that he spoke any other languages fluently. While there might have been some exposure to other languages in the vast territory of the Greek empire, Ancient Greek was the primary language of scholarship, education, and everyday life for someone of Aristotle's social standing and intellectual pursuits.
