Recorded since 1555, from Old French pyrite (12th century), from Latin pȳritēs, from Ancient Greek πυρίτης λίθος (purítēs líthos, “stone of fire, flint”) (so called because it glitters), notably the first part: adjective πυρίτης (purítēs, “of or in fire”), from πῦρ (pûr, “fire”). Analyzable as pyr- + -ite
