English alpha From the Ancient Greek ἄλφα (álpha), the first letter of the Greek alphabet, from the Phoenician 𐤀 (ʾ, “aleph”). Doublet of alif and aleph. 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.
