From 中期英語 mirour, from Old French mireor (“mirror”, literally “looker, watcher”), from mirer (“look at”), from Latin mīror (“wonder at”), from mīrus (“wonderful”), from Proto-Indo-European *smey- (“to laugh, to be glad”). Displaced native 中期英語 schewere, schawere, from 古期英語 sċēawere (“mirror”, literally “watcher”), which was also the word for "spy".

A mirror is an object that reflects light or sound in a way that preserves much of its original quality prior to its contact with the mirror. Some mirrors also filter out some wavelengths, while preserving other wavelengths in the reflection. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light. The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirrors are also used, to produce magnified or diminished images or focus light or simply distort the reflected image.
