'aristotelian' originates from Late Latin, specifically the word 'Aristotelianus', where 'Aristoteles' referred to the name of the philosopher 'Aristotle'.

'aristotelian' changed from the Medieval/Latin word 'Aristotelianus' (borrowed from the Greek name 'Aristoteles') and eventually became the modern English word 'aristotelian' through regular morphological adaptation.

Initially, it meant 'belonging to or of Aristotle', but over time it evolved into the current sense of 'in the style of, characteristic of, or relating to Aristotle's philosophy and methods'.
