Forms

leite m (plural leites)[1] Houaiss records leyte in the 14th century and lecte in the 15th.[2]

Etymology

It is inherited from Latin lac (“milk”), written Old Galician-Portuguese leite in the oldest texts.[1][2] The Latin noun was neuter, with an older nominative lacte; popular Latin made it masculine, and the masculine accusative is found already in Petronius.[3][1] Nascentes and the REW start from the form with final -e rather than the classical one.[4][5]

The same Latin word is Galician leite, Mirandese lheite, Spanish leche, Catalan llet, Occitan lach, French lait, Italian latte and Romanian lapte.[5][1] Galician and Portuguese keep the masculine gender, which reaches into León and Asturias, while Castilian, Catalan and Gascon made the word feminine.[6]

The origin of the Latin word is disputed.[1] De Vaan reconstructs Proto-Italic *(g)lagt- and Proto-Indo-European *glg-t- (“milk”), shared with Ancient Greek γάλα (gála) and Armenian.[7] Wiktionary notes that neither the set of cognates nor whether the word was inherited or borrowed is agreed.[1]

Earliest recorded meaning

Houaiss dates the word to the 13th century from Cunha's slips of medieval Portuguese.[2] The Cantigas de Santa Maria use it for a mother's milk (deitou leite das tetas “milk flowed from her breasts”) and for the holy milk of the Virgin, and once make it feminine: bẽeyta a ta leite “blessed be your milk”.[8] A cantiga d'escarnho also has it, in molheres de leite “wet nurses”.[9]

Semantic evolution

Already Morais (1789) records the transferred sense “milky sap of trees and plants” (o leite da figueira), the phrases irmão de leite “foster brother”, dentes de leite “milk teeth” and beber alguma doutrina com o leite “to learn a doctrine from earliest childhood”, and mar leite “a very calm sea”.[10] Bluteau (1712–1728) still explained milk as blood cooked twice by nature.[11]

Later senses name any milky liquid or preparation (leite de coco, leite de magnésia), and colloquially semen.[2][1] In Portugal the word is popular for “luck”, and in Rio Grande do Sul ter leite means “to be lucky”.[12][13] Brazilian dialect surveys record it for the cassava's milky sap and for the soft substance of a crab that is changing its shell.[14]

The word passed into Kabuverdianu as leti and into Macanese as lete.[1]

Timeline

  • 13th century – leite in the Cantigas de Santa Maria.[8][2]
