Etymology : A mirage is a sort of optical illusion, a reflection of light that can trick the mind into interpreting the sight as an apparently solid thing. It makes sense, therefore, that the word mirage has its roots in the concept of vision. Mirage was borrowed into English at the dawn of the 19th century from the French verb mirer (“to look at”), which also gave us the word mirror. Mirer in turn derives from Latin mirari (“to wonder at”). Mirari is also the ancestor of the English words admire, miracle, and marvel, as well as the rare adjective mirific (meaning “marvelous”).
