Pronunciation

Forms

laitier (feminine laitière, masculine plural laitiers, feminine plural laitières)[1] Middle French laictiere (feminine); Anglo-Norman letier and laitere.[2][3]

Etymology

It is formed from French lait + -ier.[4][5][6][7] Wiktionary compares Latin lactārius.[1]

The technical noun for blast-furnace slag (1676) is also derived from the same noun, according to the Grand Robert, the Petit Robert and Bloch and Wartburg.[5][8][6] Littré thinks the name was probably given for the look of the substance, though a variant litier might point to lit “bed, layer”.[2]

Earliest recorded meaning

The noun is first found about 1225 in Reclus de Molliens's Charité, for a person who sells milk.[4] The DHLF and the GLLF date it to the end of the 12th century.[9][10]

Semantic evolution

The noun “milk seller, milk deliverer” is now dated, but kept alive by La Fontaine's fable La Laitière et le pot au lait.[9][10] Littré quotes the Ménagier de Paris on a laictiere who looked after the cows.[2]

The adjective first described a female animal giving milk (vake laitiere, 1290), and une bonne laitière became a noun for such a cow in 1762.[9][4] It took the general sense “relating to milk” in 1611, as in industrie laitière and produits laitiers.[9][10]

The metallurgical laitier, the glassy matter that forms on molten metal, is recorded from 1676.[5][8][6]
