Forms

bain m (plural bains)[1]

Etymology

It is inherited from Vulgar Latin *baneum, an altered form of classical Latin balneum (“bathing; bath, (plural) public baths”), also “balineum”, borrowed from Ancient Greek βαλανεῖον (balaneîon, “bathhouse”).[2][3][4][1][5] The Greek word, usual in prose, is formed from βαλανεύς (balaneús, “bath attendant”), an Attic word with no Indo-European match; it may be a loan from an Aegean language, or be connected with βάλανος (bálanos, “acorn; peg”), the peg that stopped the hole of a bathtub.[2] In modern French “bain” is felt as an irregular noun from baigner, although that verb comes from a Latin derivative of “balneum”.[2]

Cognate with Italian bagno, Occitan banh, Catalan bany, Spanish baño and Portuguese banho.[6][7] bagne is a doublet, from Italian.[1][6]

Earliest recorded meaning

In the Chanson de Roland (about 1080) bains in the plural are a bathing place: the baths of Aix that God made for Charlemagne, vos bains que pour vous Deus i fist.[2][7][8]

Semantic evolution

Bains long named the room of a house or palace for bathing, until salle de bains replaced it, and, from the late 11th century a public bathhouse; later also a spa or seaside resort (1680).[2] The singular bain is the act of bathing and the water one bathes in from about 1155, and the tub itself from 1525.[2]

Furetière (1690) records the technical sense of a liquid in which something is dipped or heated, already present in bain-marie (14th century), a term of alchemy that probably refers to Mary the Jewess, sister of Moses, to whom alchemical works were attributed.[2][3] Bain de soleil dates from 1860.[2][6] In African French bain is also a wash with splashed water, and in Maghreb French bains-douches means a hammam.[2]
