Forms

sus (invariable)[1]

Etymology

It is inherited from Latin sūsum (“upward, above”),[2][3][4][5] a popular form found from Plautus on,[3][6] beside Classical sursum, which is a compound of sub- (“under”) and versum (“towards”).[3][2]

Cognate with Italian su, Spanish suso and Portuguese sus.[6][7]

Earliest recorded meaning

In the Sequence of Saint Eulalia (about 880) sus is an adverb meaning “up, above”: chi maent sus en ciel “who dwells up in heaven”.[3][7]

Semantic evolution

The adverb first meant “up, upward” (in heaven), and en sus “up, above” is found from about 980 to the early 17th century.[2] As a preposition meaning “on”, recorded from about 1165, sus competed for a long time with soure, sor, the ancestors of sur1, and lasted until the 17th century.[3][4]

Several old phrases have gone out of use: courir sus à qqn “to attack someone” (about 1175), mettre sus a crime “to impute it” (about 1220), mettre sus a tax “to levy it” (1478).[2] As an exclamation urging someone on, sus is found from about 1200, as in or sus, and in the classical period also as sus donc (1626).[3][2] In law, sus joined to participles referred to something already named (1219), the source of susdit.[3] En sus de meant “far from” about 1190 and survives in law for “in addition to” (1798), while en sus “in addition” is recorded by Furetière in 1690.[2][3] Bloch and Wartburg note that the adverb remains very much alive in the dialects.[6]
