Here's a breakdown:
* Ambasciator (Latin): This word literally means "messenger" or "one sent on a mission". It's formed from the verb "ambasciare", meaning "to send on a mission".
* Ambassadeur (Old French): This word directly adopted the Latin "ambasciator" and became the standard term for "ambassador" in the French language.
* Ambassador (English): This word was borrowed from the Old French "ambassadeur" during the Middle English period.
Therefore, while the word "ambassador" is now primarily an English word, its ultimate origin lies in Latin. The word has traveled through the languages of Latin, Old French, and Middle English before reaching its current form.
