Etymology

Origin of asbestos

First recorded in 1350–1400; from Latin, from Greek: literally, “unquenched, inextinguishable” from a- a- ⁶ + sbestós “quenched, extinguished” (from sbennýnai “to quench”); replacing Middle English asbeston, albeston, from Middle French, from Latin

Explanation

Asbestos is a fibrous mineral used mainly in making fireproof material. Inhaling asbestos can cause health problems such as lung cancer. Have you ever heard about people removing asbestos from a building? That's because this material — which is a fibrous amphibole used because it's fireproof — has been found to be very bad for people's health when inhaled. If you inhale bits of asbestos, which flake off over time, you could get lung cancer, a disease caused asbestosis, or other respiratory problems. Like a lot of things, it took time for people to realize asbestos was doing more harm than good.
