emphysema

English

Multiple origins. Partially from post-Classical Latin emphȳsēma (“swelling”), from Ancient Greek ἐμφῡ́σημα (emphū́sēma), from ἐμφῡσάω (emphūsáō, “to puff up”). Also borrowed from Middle French emphysema, from the same Latin source; compare French emphysème. Attested from the late 16th century.^[1]
