'monopolistic' originates from English, specifically formed from the noun 'monopoly' + the adjective-forming suffix '-istic' (the suffix ultimately from Greek '-istikos'), where 'monopoly' comes from Greek.

'monopolistic' developed in modern English from 'monopoly' (Middle English from Old French and Medieval Latin 'monopōlion'), and the suffix '-istic' (via Late Latin/Greek) was added to create the adjective 'monopolistic'.

Initially, the Greek compound conveyed the idea of 'single sale' or exclusive trade; over time it evolved to mean 'exclusive control or domination of a market,' which is the sense reflected in 'monopolistic'.
