Morphology

alkaline = alkali (transparent) = alkali + ine

Direct adjectival formation from the noun 'alkali' with the productive suffix '-ine', so the meaning 'pertaining to an alkali' is clear.

Etymology

The word alkaline comes from Arabic parts al- and qali, meaning 'the ashes of a salt plant', because people long ago used those ashes to make soap and cleaners. So, alkaline now means 'not acid' or 'basic', like those soap-like substances that break down grease.
