Pronunciation

Forms

liaison f (plural liaisons)[1] Old French loison (1260), Middle French lioison (1393); liaison from the 14th or 16th century.[2][3][4]

Etymology

It is formed from French lier + -aison, after Latin ligātiō (“a binding”).[2][3][5] Littré and the GLLF derive it from the Latin word itself,[6][4] and Bloch and Wartburg think it may go back to it.[7] The Latin noun is from ligō (“to bind”).[4][6] Rey thinks the French word inherited much of the range of the Latin one, which was a medical term for a ligature, a rhetorical term in Late Latin, “a moral bond, marriage” in Christian Latin and “a league, a pact” in Medieval Latin.[8][2]

Compare Old Occitan liazon (second half of the 12th century), which meant “finery, clothing”.[2][6]

Earliest recorded meaning

The first record is loison in the album of the architect Villard de Honnecourt (1260), for the bonding of the parts of a course of masonry in a pillar.[2][4]

Semantic evolution

The Grand Robert gives an earlier record of 1190 in the sense “manner of dressing”.[3] The cookery sense, the thickening of a sauce with egg yolk, is in the Ménagier de Paris (1393).[2][6] The 16th and 17th centuries brought the abstract senses: what links the parts of a speech (1538), a logical or psychological connection (Pascal, 1656) and the grammatical link, as in mot de liaison (1649).[8][2] Montaigne uses it for friendship (1588).[2] From about 1681 it meant a personal attachment, often in the plural and with a bad sense, as in Laclos's Les Liaisons dangereuses (1781).[2][8] Liaison amoureuse is recorded in 1694, and une liaison alone for a love affair in 1768.[8][9]

Later senses belong to music (the slur or tie, 1765), phonetics (the sounding of a final consonant before a vowel, 1867), military signals (1902), transport and telecommunications, and chemistry.[2][9][8] English took the word in the 1640s as a cookery term; its senses “intimate relationship” (1806) and “cooperation between units” (1816) followed.[10]
