'feudal' originates from Medieval Latin, specifically the word 'feodalis,' where 'feodum' meant 'fief' or 'land held in return for service.'

'feodalis' transformed into the Old French word 'feodal,' and eventually became the modern English word 'feudal' through Middle English.

Initially, it meant 'related to a fief or landholding,' but over time it evolved into its current meaning of 'relating to the system of feudalism.'
