The symbol "Au" is from the , the Latin word for "gold". The Proto-Indo-European ancestor of "aurum" was "*h₂é-h₂us-o-", meaning "glow". This word is derived from the same root (Proto-Indo-European "*h₂u̯es-" "to dawn") as "*h₂éu̯sōs", the ancestor of the Latin word Aurora, "dawn". This etymological relationship is presumably behind the frequent claim in scientific publications that "aurum" meant "shining dawn".
