Definition of asbestos

noun

  • a heat-resistant fibrous silicate mineral that can be woven into fabrics, and is used in fire-resistant and insulating materials such as brake linings:asbestos was used for pipe insulation [as modifier]:asbestos shingles
  • fabric containing asbestos.

The asbestos minerals include chrysotile ( white asbestos) and several kinds of amphibole, notably amosite ( brown asbestos) and crocidolite ( blue asbestos). The danger to health caused by breathing in highly carcinogenic asbestos particles has led to stringent control of its use

Origin:

early 17th century: via Latin from Greek asbestos 'unquenchable' (applied by Dioscurides to quicklime), from a- 'not' + sbestos (from sbennumi 'quench')
