Etymologically, the entry records: Etymology tree Proto-Indo-European *h₃ep- Proto-Indo-European *-os Proto-Indo-European *h₃épos Proto-Italic *opos Latin opus Latin opera Proto-Indo-European *-h₂ Proto-Indo-European *-éh₂ Proto-Indo-European *-tós Proto-Indo-European *-eh₂tos Proto-Italic *… 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.
