pneumatic

Etymology

It is borrowed from Latin pneumaticus (“concerned with air pressure, worked by air or wind”),^[2][3][4][5] and partly directly borrowed from Ancient Greek πνευματικός (pneumatikós, “of wind or air, of the breath; in the New Testament, spiritual”),^[2][1] from πνεῦμα (pneûma, “wind, breath, spirit”),^[2][6][7][1] from πνέω (pnéō, “to blow, breathe”).^[1][7][8] The American Heritage Dictionary, Hoad, the Shorter Oxford and the ODE give French pneumatique as a possible immediate source;^{[9][6][10][8]} Barnhart takes the word as a shortening of the earlier pneumatical (1609), perhaps influenced by the French word.^[4] The Greek noun is distantly related to sneeze,^[11][12] but pneumonia, despite its look, comes from the Greek word for the lung, altered under the influence of the word for breath.^[11]

Earliest recorded meaning

Spiritual, relating to spirit: 1624, in John Vicars's translation of George Goodwin's Babels Balm.^[2] Merriam-Webster also dates the word to 1624.^[12] Word Origins notes that this sense, from New Testament Greek, is the first recorded in English.^[13]

Semantic evolution

The Greeks associated breath with the soul, which is why the Greek adjective came to mean "spiritual".^[13] In English the physical sense, relating to or worked by wind or air, followed in 1654,^[2] and Etymonline dates the word to the 1650s in this sense.^[3] It was used of wind instruments and organs from 1695, of breathing from 1681, of gases from 1735 and of the air-filled bones of birds from 1763.^[2] From the mid-19th century it described things inflated with air (1862), such as the pneumatic tyre, called simply a pneumatic from 1890;^[2][13] the pneumatic dispatch tube had its name by 1859.^[3] The inflated sense opened the way to a humorous use for a woman with a full figure:^[13] the OED records it from 1910, in O. Henry,^[2] earlier than T. S. Eliot's "Gives promise of pneumatic bliss" (1919), which Word Origins calls the first.^[13]
