Pronunciation

  • 5th-century BC Attic: /pneu̯.mo.ní.aː/[1]
  • 4th-century AD Koine: /pneβ.moˈni.a/[1]
  • 10th-century Byzantine: /pnev.moˈni.a/[1]

Forms

πνευμονίᾱ (pneumoníā) f (genitive πνευμονίας); first declension[1][2] Also πλευμονία (pleumonía), the form LSJ heads the word under.[3][1]

Etymology

It is formed from Ancient Greek πνεύμων (pneúmōn, “lung”) + -ία (-ía), an abstract noun of disease.[1][2][4] πνεύμων (pneúmōn) is the usual spelling of older πλεύμων (pleúmōn), remodelled after πνέω (pnéō, “to breathe”) and πνεῦμα (pneûma).[5][6]

The older noun is from Proto-Hellenic *pléwmōn, from Proto-Indo-European *pléwmō (“lung”).[1] Beekes and Chantraine compare Sanskrit क्लोमन् (klóman, “right lung”) and Latin pulmō, though the correspondences are not exact, and Beekes also compares Lithuanian plaũčiai (“lungs”).[5][6] Chantraine reports the derivation from πλέω (pléō, “to float”), the lung being the organ that floats in water.[6]

Earliest recorded meaning

The oldest records are a comic fragment of unknown author, in the form πλευμονία (pleumonía), and the physician Mnesitheus, quoted by Plutarch, both for a disease of the lungs.[3][5]

Semantic evolution

In Greek medicine the common name of the disease was the compound περιπλευμονία (peripleumonía); πνευμονία and πλευμονία were the rarer forms.[5] The word lived on in Byzantine and vernacular Greek, where a medical text pairs πλευμονία with cough among the ills it treats, and dialects still have forms like πλεμονία (plemonía).[7]

Modern Latin took it up as Latin pneumonia, the source of English pneumonia (about 1600), French pneumonie and the other European words.[1][8] Modern Greek πνευμονία (pnevmonía) is a learned form of the Hellenistic word, the name of the acute infection of the lungs.[9][10]

Timeline

  • 1st–2nd century AD – Plutarch quotes Mnesitheus for the disease of the lungs.[3][2][11]
  • 10th century AD – The Hippiatrica, the Byzantine veterinary collection, has the word in a conjectured reading.[3][11]
  • 1100–1669 – Vernacular medical texts use πλευμονία (pleumonía) for inflammation of the lungs.[7]
  • About 1600 – English pneumonia is first recorded, from Modern Latin.[8]
  • Modern Greek – The word is used as a learned medical term for the infection of the lungs.[9]
