Forms

ajo m (plural ajos)[1] Old Spanish wrote aio, axo and ayo;[2] Asturian has ayu, Leonese allo and Navarrese aillo or ailo.[2][3]

Etymology

It is inherited from Latin alium (“garlic”), also written allium.[3][4][5][1] The classical form has a single /l/, and the spelling with ⟨ll⟩ appears in inscriptions from the 1st century AD.[6] A Mozarabic form alyo is recorded in a botanical glossary of about 1100.[2]

The same Latin word is Portuguese alho, Galician allo, Asturian ayu, Aragonese allo, Catalan all, Occitan alh, French ail, Italian aglio, Sardinian azu and Romanian ai.[7][8][3][9]

De Vaan finds no accepted etymology for the Latin word.[6] He mentions a speculative derivation from āla (“wing”), the bulb being divided into wings, like Old High German klobalouh (“garlic”), named for its cloves.[6] The Latin word has also been compared with a Greek gloss for vegetables used among the Italians, which may come from another Italic language.[6][1] The DHLF thinks it probably a native Italic word.[10]

Earliest recorded meaning

The Fuero de Zorita de los Canes (1218–c. 1250) lists un braço de aios “an armful of garlic” among the payments due to a ploughman, beside salt and onions.[11] Corominas gives Berceo as the first record: in the Vida de Santo Domingo de Silos (c. 1236) a broken chain is ground up faster than ajos en el mortero “garlic in a mortar”.[3][11]

Semantic evolution

Garlic was cheap and common: the Libro de Alexandre says a thing was not worth un ajo, and a source of Alfonso X prices una cabeça d'aios “a head of garlic” at a silver penny.[11][12] Covarrubias in 1611 calls it the labourers' theriac, giving warmth and strength to those who work in the fields.[13]

The Diccionario de Autoridades (1726) adds the sauce made with garlic, which takes the name of the dish (ajo pollo, ajo comino), and a figurative sense, the make-up women use on their faces.[14] In 1817 the Academy added a shady business in which several people take part, as in andar en el ajo.[15] In Cuba the phrase means rather the heart of a matter.[16]

Spanish carried the word to the Americas and Asia, and it was borrowed into many languages there, including Tagalog aho, Quechua ahus, Guarani áho and Mapudungun ako.[1]
