This History of Aureate Is Golden

Aureate is among several adjectives in English pertaining to gold that derive from the Latin name for the metal, aurum. While its relatives auriferous and auric are more likely to appear in scientific contexts to describe substances containing or made from gold (or Au, to use its chemical symbol), aureate has tended to have a more literary allure since it was first used in English in the early 15th century. Over time, the word's use was extended from "golden" to "resplendent," and it finally lost some of its luster as it came to mean "grandiloquent."
