'ambassade' originates from Old French, specifically the word 'ambassade', where 'amb-' meant 'around' and '-assade' was a suffix used in forming nouns.

'ambassade' changed from the Old French word 'ambassade' and eventually became the modern English word 'embassy'.

Initially, it meant 'a mission or delegation', but over time it evolved into its current meaning of 'the official residence or offices of an ambassador'.
