Etymologically, the entry records: From the French surname Dirac, probably from the French town by that name in Charente, from Medieval Latin Adiraco, Dyracum, from a Gallo-Roman name, Latin Atirius (a derivative of Atilius), or alternatively a Frankish/Germanic name *Adarus, in either case … Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is Dirac, spelled D-I-R-A-C, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
