Forms

lessive f (plural lessives)[1] Old French lissive, leissive, loissive;[2][3][4] Anglo-Norman also lexive.[2][3][4]

Etymology

It is inherited from Old French lissive, inherited from Latin lixīva (“lye”), the feminine of lixīvus (“of lye”) used as a noun, from lix (“lye, ash water”).[2][5][3][1] The Latin adjective went with cinis (“ash”), whose gender wavered, so the neuter lixīvum also existed; it gave Old and Middle French lessif, still used south of a line from southern Lorraine to the mouth of the Loire.[2][3][6]

The regular Central French outcome would have an /oi/; the TLFi explains the form either by dissimilation of the first /i/ or as a western dialect form, which Bloch and Wartburg and the DHLF prefer.[2][6][3] Rey thinks the Latin word for lye may be borrowed, perhaps from Etruscan.[3]

Cognate with Italian lisciva, Spanish lejía, Catalan lleixiu and Romanian leșie.[2][3][1]

Earliest recorded meaning

The first record, lissive in the Conquête de Jérusalem (about 1200), is a solution of ash used for washing a person.[2][3]

Semantic evolution

From the late 13th century it was the alkaline solution, first made with ash, used to clean dirty linen.[2][3] In the mid-15th century the Évangiles des Quenouilles have faire la lessive “to do the washing” and the sense “linen being washed”; the older word buée, usual until the 16th century, now survives only in the dialects.[2][3]

Figurative senses followed: a heavy loss at gaming (Saint-Simon, 1740–55) and the removal of unwanted people from a firm or administration (1901).[2] In 1926 the word came to name washing powder.[2][7]
