Forms

gai (feminine gaie, masculine plural gais, feminine plural gaies)[1] Old French also had the form jai in the 13th century.[2][3] Anglo-Norman spellings include gay, gaye and wai.[4]

Etymology

The origin is disputed.[2][5] Bloch and Wartburg, the Grand Robert and the DHLF take it as borrowed from Old Occitan gai (“lively, merry”), a word of the troubadours' vocabulary, which is recorded earlier than the French word;[6][7][5] the Occitan word in turn is usually traced to Gothic *𐌲𐌰𐌷𐌴𐌹𐍃 (*gaheis, “impetuous”), related to Old High German gāhi (“impetuous, sudden”) and modern German jäh (“abrupt”).[6][2][1] The FEW places the word under the Gothic form and explains the Occitan route by the influence of the troubadours.[8][2] The TLFi and the DHLF think it more probable that the word came straight from the Old High German word, which accounts for the 13th-century form jai;[2][5] the prevailing ⟨g⟩ is put down to constant interference with gaillard.[2][9]

P. Guiraud, noting that the idea of freedom is stronger than that of impetuosity in many old uses (in heraldry, of a horse without bridle or harness), proposed instead a popular outcome of Latin vagus (“wandering, unrestrained”), without excluding Germanic influence;[5][7] Wiktionary cites Liberman for the Latin view as well, which would make the word a doublet of vague3.[1] Littré mentioned, only to set it aside, the name Latin Gaius.[10]

Italian gaio was borrowed from French,[6][9] as was English gay, from Old French in the late 14th century.[11]

Earliest recorded meaning

The TLFi's first record is from the second half of the 11th century, of a person in a cheerful mood or a face that shows gaiety;[2] Wace uses it about 1155.[2] The Anglo-Norman Dictionary has it from 1155, meaning “happy, cheerful”.[4]

Semantic evolution

From people, gai passed to things that show or inspire gaiety (about 1300): a temps gai is pleasant weather (about 1225), and vert gai a light, yellowish green (about 1300).[2][5] Cotgrave records the sense “tipsy” in 1611, whence avoir le vin gai “to be a cheerful drinker” (Académie 1740) and être un peu gai (Voltaire, 1775).[3][5] In Belgian French a personne gaie is amusing, pleasant company.[5]

In the 1960s gai took over the American English sense of gay “homosexual”, competing with the English form gay.[5][12] The proverbial gai comme un pinson “very cheerful” is recorded by Littré.[10][12]
