Etymology

Origin of azure

First recorded in 1275–1325; Middle English asure, from Anglo-French, Old French, ultimately alteration of Arabic al-lazuwar(d) (by misdividing the initial l together with the article), from Persian lāzhuward “lapis lazuli,” perhaps from Sanskrit rājāvarta

Explanation

Looking for a fancier way to describe the deep blue sky on a crisp fall day or the jewel-toned waters of the Caribbean? Try azure. Some people might describe the color azure as sapphire in hue, but in fact there's another gem responsible for this word. At its root, azure comes to us from a French mistranslation of the Arabic word (al)-lazaward, which means “lapis lazuli” — the dazzling deep blue stone that's very common in Afghanistan. The Arabic word actually refers to an area of Turkestan where Marco Polo collected lapis lazuli for friends back home.
