Etymologically, the entry records: From Middle English professor, professour, from Anglo-Norman proffessur and its etymon Latin professor (“declarer, person who claims knowledge”), from the past participle stem of profiteor (“profess”). By surface analysis, profess + -or. 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 professor, spelled P-R-O-F-E-S-S-O-R, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
