Pronunciation

  • UK: /ˌɛə.ɹəʊˈnɔː.tɪks/[1]
  • US: /ˌɛɚ.oʊˈnɔ.tɪks/[1]

Etymology

It is formed from English aeronautic + -ics,[2][3][4] after French aéronautique and New Latin aeronautica.[4][5] Barnhart allows either that or a formation from the New Latin word with the English suffix,[3] and the Shorter Oxford and the Oxford Dictionary of English take the New Latin word as the source.[6][7] The OED records aeronautica in English book titles from 1753, in the Supplement to Chambers's “Cyclopædia”;[2][3] it compares the French word, recorded from 1824.[2] The adjective aeronautic is recorded from 1754 in the OED,[2] from 1784 in Etymonline and Barnhart, which take it from the French word;[8][3] the OED forms it from aero- and nautic and compares the Latin aeronauticus, used by J. C. Sturm in 1676.[2] The first part is from Ancient Greek ἀήρ (aḗr, “air”), genitive ἀέρος (aéros);[3][1] the second is nautique (“of ships”), from Latin nauticus,[8][3] from Ancient Greek ναυτικός (nautikós, “relating to sailing”), from ναύτης (naútēs, “sailor”).[8][1]

Earliest recorded meaning

The art of travelling through the air, at first by balloon: 1824, in the Supplement to the Encyclopædia Britannica.[2][8][3] Merriam-Webster's Unabridged gives 1798 as its first known use.[4]

Semantic evolution

The word belongs to the age of the balloon: aeronaut, a balloonist, was taken from French aéronaute in 1784,[8] and Etymonline glosses the first sense of aeronautics as aerial navigation by balloon.[8] Merriam-Webster's Unabridged keeps this sense, sailing through the air in lighter-than-air craft, as archaic.[4] With the aeroplane the word came to mean the science and practice of controlled flight in general, and later also the design and building of aircraft.[2][4] The idea behind it, a ship sailing through the air as a boat sails through water, is older: the OED points to Francesco Lana Terzi's airship proposal of 1670.[2]
