Etymology: "Aluminates" is the plural of "aluminate," a chemical term for a salt or ester of aluminic acid, the acid formed from aluminium oxide. The noun is built in the ordinary way for chemistry: "aluminic" (from "aluminium," the element, plus the adjective-forming "-ic") gives the base, and the suffix "-ate" marks a salt or ester of that acid. The "-ate" ending itself comes from Latin "-atus," the past participle ending used to form many chemical names, so the word is a modern technical coinage built from parts that were already in use. Because the word is a formal chemical label rather than an everyday term, its history is simply a matter of naming a class of compounds. The meaning given for this entry, "to enlighten or clarify," does not match the chemical sense at all. The chemical term refers to compounds containing aluminium and oxygen, such as sodium aluminate, which is used in water treatment and in making some cements.
