Word History

Etymology

Middle English ambassatour, ambassiatour "diplomatic emissary, envoy, messenger," borrowed from Anglo-French & Medieval Latin; Anglo-French ambaxiatour, ambassatour (continental Middle French also embassator, ambassadeur), borrowed from Medieval Latin ambasciātor, ambassātor, from ambiasciāre "to communicate, send a message, send an envoy" (derivative of Late Latin ambascia, ambassia "mission, errand, task, journey") + Latin -tor, agent suffix — more at embassy

Note: The current form of the word with -d-, which becomes common in early Modern English, is dependent on Middle French (and French) ambassadeur, borrowed from Italian ambasciatore, probably borrowed from Old Occitan ambayssador. Regarding the variation between initial am- and em-, see the note at embassy. As the Oxford English Dictionary, third edition, remarks, the form embassador was frequent in early Modern English, up to ca. 1700, and sporadic thereafter; the prevalence of the am- form is probably due at least in part to the influence of French ambassadeur. Though ambassador was apparently always more common in American English, Noah Webster preferred embassador, as he notes at the entry for ambassador in An American Dictionary of the English Language (1828): "This is the more common orthography; but good authors write also embassador; and as the orthography of embassy is established, it would be better to write embassador."
