Pronunciation

Forms

poil m (plural poils)[1] Old French peil (1080); poil from about 1175.[2][3][4]

Etymology

It is inherited from Old French peil, inherited from Latin pilus (“a hair; figuratively, a trifle”),[5][2][3][6][7][1] which named a single hair, as opposed to the collective capillus (see cheveu), and with a negation a thing of no importance.[2] Its origin is obscure: Rey notes that there is no Indo-European noun for this notion.[2][8]

Cognate with Romanian păr, Italian pelo, Spanish pelo, Occitan pel, Catalan pèl, Portuguese pelo and Basque bilo.[8][9]

Earliest recorded meaning

The Chanson de Roland (about 1100) uses peil collectively for a person's hair: Et Blancandrins i vint al chenu peil, “Blancandrin came there with his white hair”, and deit hum perdre e del quir e del peil, “a man must lose skin and hair” for his lord.[5][10]

Semantic evolution

From the collective sense came the now dated uses for a beard (1655) and for the hair of the head, and by analogy the coat of an animal (Chrétien de Troyes, about 1170, of a horse).[2][5] A single hair is recorded before the end of the 12th century, and a fur pelt about 1190.[2] It was extended to the pile of velvet (1395), to poil de chèvre (1663), to the down of plants (15th century) and poil à gratter (1890).[2][5] Old French already had poil d'erbe for a trifle (13th century).[5]

Many phrases followed: encontre poil (1176–84), later à rebrousse-poil, un brave à trois poils (Molière, 1659); de tout poil (La Fontaine, 1671); avoir un poil dans la main “to be lazy” (1808); être de mauvais poil (1833); à poil “stark naked” (1858); au poil “just right” (1918).[5][2][4] The derivative poilu took in popular French the sense “strong, brave”, and the soldier of 1914–18.[6]
