Etymology

edit

Of late 18th–early 19th c. as a neologism from άλευρον (álevron, flour) +‎ γαία (gaía, earth), in reference to the flour-like consistency of this alkaline earth oxide. The term was preferred by scholars of the Greek Enlightenment, who were reluctant to adopt μαγνησία (magnisía), a calque of Late Latin magnesia, due to confusion with the region name Μαγνησία (Magnisía).
