'admiralty' originates from Middle English, specifically the word 'admiralte,' where 'admiral' referred to a naval commander.

'admiralte' transformed into the modern English word 'admiralty' through the influence of Old French 'amiral' and Arabic 'amir al-bahr' meaning 'commander of the sea'.

Initially, it meant 'the office of an admiral,' but over time it evolved to include 'jurisdiction over maritime affairs'.
