Overview
Asbestos is a naturally occurring fibrous silicate mineral.

Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, …
Etymology
The word "asbestos", first used in the 1600s, ultimately derives from the Ancient Greek: ἄσβεστος, meaning "unquenchable" or "inextinguishable". The name reflects use of the substance for wicks that would never burn up.
It was adopted into English via the Old French abestos, which in turn got the word from Greek via Latin, but in the original Greek, it actually referred to quicklime. It is said by the Oxford English Dic…
