'apanaged' originates from 'Old French', specifically the word 'apanage', where 'pan' (from Latin 'panis') meant 'bread' or 'provision' (hence an allowance or maintenance).

'apanaged' changed from the Old French word 'apanage', which came from Medieval Latin 'apanagium' (from Latin elements such as 'ad-' + 'panis'), and eventually entered modern English as 'apanage' with derived forms like 'apanaged'.

Initially, it meant 'an allowance or provision (literally for bread or maintenance)'; over time it evolved into the sense 'a grant of land, income, or privilege (especially for a junior royal)', and 'apanaged' now means 'provided as such a grant'.
