Etymologically, the entry records: First attested in 1677. From alkali + -ine, ultimately from Arabic اَلْقِلْي (al-qily, “alkali, ashes of the saltwort”), related to قَلَى (qalā, “to roast in a pan, fry”). 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 alkaline, spelled A-L-K-A-L-I-N-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
