'aristotelism' originates from Modern English, formed from the name 'Aristotle' plus the suffix '-ism'; the name 'Aristotle' ultimately comes from Greek 'Aristotélēs', where 'aristos' meant 'best' and 'télos' meant 'end' or 'purpose'.

'Aristotle' entered English via Latin 'Aristoteles' (from Greek 'Aristotélēs'), and the noun 'aristotelism' was formed in modern English by adding the suffix '-ism' to denote the doctrines or system associated with that name.

Initially it referred specifically to the teachings associated with the historical figure Aristotle; over time it has been used more broadly to denote adherence to or influence by Aristotelian principles in various intellectual contexts.
