'nonfeudalistic' originates from English, specifically the prefix 'non-' and the adjective 'feudalistic', where 'non-' meant 'not' and 'feudalistic' meant 'relating to feudalism'.

'Feudalistic' developed from 'feudal' (from Middle English and Old French 'feodal' / Medieval Latin 'feodalis', related to 'feodum' meaning 'fief'); the negative prefix 'non-' was added in modern English to form 'nonfeudalistic'.

Initially related words referred to 'fief' or 'land held in return for service'; over time 'feudalistic' came to mean 'relating to the social and political structures of feudalism', and 'nonfeudalistic' evolved to mean 'not characterized by those structures'.
