means A naturally occurring fibrous mineral once prized for being able to resist fire, heat, and electricity — and later found to cause fatal lung disease when its fibers are inhaled.

from From Greek 'asbestos,' meaning 'unquenchable' or 'inextinguishable' — fittingly, the ancient Greeks and Romans noted how cloth woven from it survived flame untouched. The irony runs deep: a word that praised the material's refusal to burn ended up marking a substance that quietly burned through the lungs of everyone who worked with it.
