'allodia' originates from Medieval Latin, specifically the word 'allodium,' where 'al-' meant 'all' and 'od' meant 'property.'

'allodium' transformed into the English word 'allodia' and eventually became the modern English term 'allodial' to describe such land ownership.

Initially, it meant 'complete ownership of land,' and this meaning has largely remained the same in modern usage.
