Pneumokoniosis

Part of speech: noun

Definitions

Etymology: The word is a medical coinage, and its history is a tidy story of an accidental spelling change. The original form was "pneumonoconiosis," built from "pneumon," the Greek word for lung, and "konis," meaning dust, with the "-osis" suffix that marks a diseased condition. The middle "-on-" was later dropped, leaving the shorter form now standard, "pneumoconiosis." The alternative spelling "pneumokoniosis" is a further variant that swaps the "c" in "coniosis" for a "k," following the Greek spelling of the dust element. It is a modern construction rather than something the ancient Greeks used: the components are classical, but the compound itself was assembled in medicine to name a group of lung diseases caused by inhaled dust. The "pneumo-" element means "lung" and appears in other medical terms such as pneumonia, while "-coniosis" follows the pattern of names for dust-related conditions. Read together, the parts say plainly what the disease is: a diseased state of the lungs caused by dust.
