Forms

leiteiro m (plural leiteiros, feminine leiteira, feminine plural leiteiras)[1]

Etymology

It is formed from Portuguese leite + -eiro.[2][3][4] Wiktionary and the Porto dictionary trace it instead to Latin lactārius (“of milk”), an adjective formed from lac (“milk”).[1][5][6]

Corresponding words are Galician leiteiro, Spanish lechero and French laitier; the Spanish word is derived from the Latin adjective, the French one is formed from its noun for milk.[7][8][1]

Semantic evolution

Houaiss dates the adjective, “giving milk”, to 1603 and the noun “person who sells milk” to 1789.[2] Cunha dates the word to the 18th century.[9] Morais in 1789 has both, the milk seller and plants that give a milky juice.[10] Vieira adds the phrases cabra leiteira and espiga leiteira.[11]

In Brazil the noun names several shrubs and trees with abundant milky latex, and a fish of the north-east.[2][12][13] A popular sense “lucky, especially at gambling” is labelled Brazilian by Houaiss and Aurélio but is also recorded in Portugal. [2][4][3][14]
