Pronunciation

  • /aˈeɾeo/, [aˈe.ɾe.o][1]

Forms

aéreo (feminine aérea, masculine plural aéreos, feminine plural aéreas)[1] Older texts have the forms aerio and aero;[2] airio is recorded in Ecuador and Mexico, and the popular ario in Mexico.[2]

Etymology

It is borrowed from Latin āerius (“of the air”).[3][4][1][5] The DLE and Moliner give the variant aereus as the source.[6][7]

The Latin word is from Ancient Greek ἀέριος (aérios, “in the air”), from ἀήρ (aḗr, “air, mist”).[1][8] Gómez de Silva puts it in one family with aire and the compounds in aero-.[5]

Earliest recorded meaning

Corominas dates it to 1515, in Fernández de Villegas.[3][4] The TDHLE and the Alfonsine dictionary have much older records in astrology: the Libro conplido of 1254 divides the signs of the zodiac into ígneos e térreos e aéreos e aquáticos, “fiery, earthy, airy and watery”, and the Libro de las cruces of 1259 speaks of the signos aereos.[2][9]

Semantic evolution

In the 15th to 17th centuries aéreo was mostly a term of natural philosophy, the quality of the element air beside the earthy, watery and fiery.[2] Quevedo in 1607 jokes about aéreo bailiffs, the informers who “give wind”.[2] From the 17th century it was applied to flying animals, opposed to land and water animals, and in the 19th century to the air passages of the body (vías aéreas).[2]

The figurative sense “fanciful, without foundation” is in the Academy's dictionary of 1884.[10] In the 20th century it came to refer to aviation (líneas aéreas “airlines”, navegación aérea).[2][6]
