Pronunciation

Forms

sueur f (plural sueurs)[1] Old French sudor (about 980), suor (about 1155) and sueur (about 1260 or 1307).[2][3][4] Anglo-Norman had suour and sour.[5]

Etymology

It is inherited from Old French suor, inherited from Latin sūdor (“sweat; moisture; toil, hardship”), in its accusative sūdōrem, derived from sūdō (“to sweat”).[6][2][7][8] Wiktionary traces the Latin word to Proto-Indo-European *sweyd-.[1] Littré compares Old English swāt and Old High German sweiz.[9]

Cognate with Italian sudore, Romanian sudoare, Catalan suor, Spanish sudor and Portuguese suor.[10][7]

Earliest recorded meaning

It first appears as sudor in the Passion of Clermont (late 10th century), for the watery fluid that comes out through the pores of the skin.[6][2]

Semantic evolution

As in Latin, the word is both the fluid and, figuratively, the symbol of toil: estre au travail e au süor (1210–1230).[6][2] En sueur “sweating” goes back to Wace (about 1155),[11][2] and froide suour (13th century) became sueur froide (1549), the cold sweat of fear or illness.[2][11] Sueur de sang is found from 1648 or 1658.[6][2]

Of moisture exuded by things it is recorded in 1309.[6] The phrases of hard labour changed over time: à la sueur de son visage (early 14th century), de son corps (early 15th century) and à la sueur de son front (1762).[2][6]
