What does pneumoconiosis mean?
Pneumoconiosis is a broad medical term for chronic lung disease caused by inhaling dust, especially mineral dust encountered in industrial work. The condition includes diseases such as coal workers' pneumoconiosis, silicosis, and asbestosis, which can produce scarring in the lungs and gradually reduce breathing capacity. The word is especially associated with occupational exposure, although the disease can also result from other forms of prolonged dust inhalation. Its name reflects its origins: Greek pneumōn, meaning “lung,” and konis, meaning “dust.” In medical and workplace-safety discussions, the term is precise and technically important, although it is rarely used in ordinary conversation. Its broader significance lies in showing how preventable exposure to industrial dust can have lifelong effects on health.
nounA chronic lung disease caused by inhaling mineral or other industrial dusts, such as coal dust, silica, or asbestos. It may lead to scarring, fibrosis, and progressive impairment of lung function.
- A group of chronic lung diseases caused by the inhalation of dust or other airborne particles, especially in occupational settings.
"Years of exposure to silica dust at the quarry caused severe pneumoconiosis."
"The radiologist diagnosed early pneumoconiosis in the mine worker."

A formidable medical term built from Greek words for “lung” and “dust”: pneumoconiosis is literally the dust disease of the lungs.

Where does pneumoconiosis come from?
The word was formed in the 19th century from Greek pneumōn, meaning “lung,” and kónis, meaning “dust,” together with the suffix -osis, denoting a disease or abnormal condition. Its development followed the growth of industrial medicine and the recognition that inhaling certain dusts caused distinctive forms of lung scarring. Related English words, including pneumonia and pneumonic, also draw on the Greek word for lung.
