A fortuneteller might claim your aura is aureate, but the two words don’t have the same etymology. “Aura” comes from the Latin for “breeze,” while “aureate” comes from the Latin “aurum,” which means “gold.” When describing language, “aureate” means “fancy or elaborate.” But the process of aureation describes how languages evolve. When one language is improved or heightened by borrowing from another, that’s called “aureation.” Loanwords, such as “hors d’oevres” from French, are considered a form of aureation.
