Etymology: Albite is a plain technical coinage, and its history is in its colour. The mineral is a white or nearly colourless sodium-rich feldspar, and its name comes from Latin "albus", meaning "white", the same root that gives English words such as "albumen" and "albino". The Latin stem was given the common mineralogical ending "-ite", which chemists and geologists have long used to name rocks, minerals and salts, so the word simply means "the white one". The name is therefore a descriptive label rather than a person's name or a myth. Its modern use as a mineral term follows the same pattern as the many other feldspar names, which are usually based on composition or appearance.
