Pronunciation

Forms

ruisseau m (plural ruisseaux)[1] Old French russeal (about 1120), ruisel (about 1130), ruissel (about 1155), then ruisseau (about 1380).[2][3][4]

Etymology

It is inherited from Old French ruissel, inherited from Vulgar Latin *rivuscellus, a diminutive of Latin rīvus (“small stream”), the source of ru.[5][2][6][7] It is formed like *ramuscellus, the source of rinceau.[5][6] The word belongs only to the north of the Gallo-Romance area.[6]

Italian ruscello comes from the same Vulgar Latin form according to the REW;[8][9] Littré took it for a borrowing from French.[8][9]

Earliest recorded meaning

It first appears as russeal in the Cambridge Psalter, for a small stream;[5][4] the Grand Robert and GLLF date it about 1120, the TLFi to the mid-12th century.[3][4][5]

Semantic evolution

From the start the word also named whatever seems to flow without end (Wace, about 1155), and ruisseaux de blood, tears and so on is used of any liquid flowing in abundance, with metaphors such as un ruisseau de perles (1573–1575).[5][2] By metonymy it named the bed of the stream (1538).[2][4] From the late 14th century (Eustache Deschamps) it was the water running along the street and the gutter that carried it,[5] hence a symbol of degradation: Molière's ruisseaux des Halles (1668) and laisser qqn dans le ruisseau in Saint-Simon.[5][2] The proverb les petits ruisseaux font les grandes rivières is recorded by Oudin in 1640.[5][2]
