Pronunciation

  • US: /ˈpʌl.məˌnɛ.ɹi/[1]

Etymology

It is borrowed from Latin pulmōnārius (“of the lungs”),[2][3][4][5] perhaps under the influence of French pulmonaire.[6][7] In classical Latin pulmōnārius meant having a lung disease; it meant good for the lungs in the 4th century, and of the lungs by 1661.[2] It is formed from pulmō (“lung”) and -ārius.[2][8][9] Pulmō is cognate with Ancient Greek πλεύμων (pleúmōn, “lung”), beside which Greek also had πνεύμων (pneúmōn),[10][9] and with Lithuanian plaučiai (“lungs”).[7][10][8] Etymonline and Barnhart trace these to Proto-Indo-European *pleumon- (“lung”), from the root *pleu- (“to flow, float, swim”):[7][6][10] the lungs would be "the floaters", because the lungs of a slaughtered animal float in water while the heart and liver sink.[7][6][10] Klein compares English lights for the lungs, named for their lightness.[10][7]

Earliest recorded meaning

Of or relating to the lungs: 1668, in the Philosophical Transactions of the Royal Society.[2][8] Barnhart and Etymonline date it from 1704, in John Harris's Lexicon Technicum.[6][7]

Semantic evolution

Its uses in anatomy and medicine came early: pulmonary was a noun for a blood vessel of the lungs from 1707, and it described diseases of the lungs from 1708.[2] From 1712 it was also used of people with lung disease, at first especially tuberculosis.[2] In zoology it described breathing by means of lungs (1787, translating French pulmonaire) and organs that resemble lungs, such as the breathing cavity of snails and slugs (1792).[2] Johnson (1755) defined it as "belonging to the lungs", quoting Arbuthnot on the pulmonary artery.[11] In the mid 17th century pulmonary was also a noun for the plant lungwort.[5][8]
