Etymology: "Pyritiferous" is a plain technical compound built from "pyrite" and "-ferous," meaning "bearing" or "producing." The Latin "-ferous" comes from "ferre," "to bear," so the word literally means "bearing pyrite," and it is a modern scientific coinage rather than an ancient term. The first half traces back to Ancient Greek "pŭrī́tēs," an adjective meaning "of fire" or "fiery," formed from "pûr," "fire." Greek writers applied it to stones that could strike sparks, and the Latin "pȳritēs" carried that sense forward. The mineral name passed through Old French "pyrite" into English, where it is attested in the sense of the iron sulfide mineral that gave the stone its name. The "-i-" linking vowel appears in the English word as a joining element between the two parts.
