Forms

sous[1] Old French sost (about 980), soz and suz (late 11th century), sos, with an etymological ⟨b⟩ soubz, soubs, sous from about 1180.[2][3]

Etymology

It is inherited from Old French soz, inherited from Latin subtus (“below, underneath”), an adverb in classical Latin and a preposition in imperial and Late Latin.[2][4][3][1][5] Rare in texts, this derivative of sub (“under”) must have been common in speech; the preposition “sub” itself left few traces.[2][4] “Sub” goes back to an Indo-European “*upo”, seen in Ancient Greek ὑπό (hupó) and Sanskrit उप (úpa).[6][7]

Cognate with Italian sotto, Occitan sot and Catalan sots; Spanish so, from “sub”, is now less used than “bajo”.[6][4] In many Gallo-Romance dialects “sous” competes with dessous.[4]

Earliest recorded meaning

It is first found as sost in the Jonas fragment of Valenciennes (about 980), introducing something overhung by another thing without touching it.[8][2]

Semantic evolution

Sous marks a position below.[2] About 1050 it was used of a thing resting under another (suz ciel “under heaven”), and by 1080 of a surface, as in sous terre.[8][2] About 1160–1175 it introduced a dominating place, the basis of place names such as La Ferté-sous-Jouarre.[8][2] From the 15th century it meant “behind (what hides)”, as in sous couleur de and sous tel nom (1559), and it expresses subordination in sous les ordres de (1363) and servir sous quelqu'un (1405).[8][2] Metaphorical phrases include sous les armes (about 1650), sous le drapeau (1694), sous les drapeaux “serving as a soldier” (1835) and sous les verrous (1829).[2] Belgian French says sous eau without the article.[2]
