Forms
aer n (plural aere)[1] The plural aere is used mainly in the expression a-și da aere “to put on airs”.[2]
Etymology
It is inherited from Latin āēr (“air”), itself from Ancient Greek ἀήρ (aḗr).[3][4][5][1] Ciorănescu, following Pușcariu, the REW and the DA, takes it directly from Latin.[4][6] Tiktin points out that old Romanian did borrow some Latin words in writing (testament, austru, pedestru, asin), but he too notes that the word is generally held to continue the Latin one and that it exists in every Romanian dialect.[7]
It survives in all four branches: Aromanian aeru, Megleno-Romanian aeru and Istro-Romanian åier.[4][3] DELR writes the Aromanian form áir, and Ciorănescu notes a further Aromanian aera taken from Modern Greek αέρας (aéras).[3][4] The sense “look, bearing, manner” follows French air, and the old sense “tune, melody” is a calque of the same French word and of Italian aria.[3][7] Other Romance cognates include Sardinian aera, Occitan aire, Spanish aire and Portuguese ar, and Ciorănescu also compares Albanian ajër.[4][8]
Earliest recorded meaning
DELR dates the first certain record to 1581, in Coresi's homiliary, and Tiktin gives the same year.[3][7] A form aieru in a Slavonic manuscript of about 1390–1410 may be older, but DELR counts it as uncertain, since the word also exists in Slavonic.[3] The sense was the physical one from the start: an Apostol of 1683 says that the visible world was made of four elements, „den foc, den aer, den apă, den pământ” “of fire, of air, of water, of earth”.[6][5]
Semantic evolution
Besides the gas itself, the older language used the word for the weather or climate and for the sky, the space between earth and heaven.[6][5] The figurative “atmosphere, influence of a place” appears in the 19th century.[6] In the same century French gave the sense “look, appearance, bearing”, from which comes a-și da aere “to give oneself airs”; the sense “tune, melody”, also from French and Italian, did not last.[3][7][2]
Most of the word's family came from French on the same Latin base, and Ciorănescu notes that these neologisms clashed with the inherited word: the verb aera looks like a derivative of aer but reproduces French aérer.[4][3] Aerisi “to air” is older, recorded from 1795, and comes from Modern Greek αερίζω (aerízo).[3] DELR treats aeresc, which the DA cites from Cantemir, as a misreading of ceresc “heavenly” in the modern editions.[3]
