Forms

suar (first-person singular present suo, first-person singular preterite suei, past participle suado)[1] Houaiss records the 14th-century spelling ssuar.[2]

Etymology

It is inherited from Latin sūdō (“to sweat”), written Old Galician-Portuguese suar in the oldest texts.[2][3][4][1]

The same Latin verb is Galician suar, Catalan suar, French suer, Italian sudare and Spanish sudar.[5][1] The Latin -d- between vowels has disappeared in Portuguese, Galician, Catalan and Old Spanish suar.[6] García de Diego takes the Spanish form that kept it for a learned one.[6]

According to de Vaan the Latin verb was formed from a noun Proto-Indo-European *swoyd-o- (“sweat”), which survives in Indo-Iranian and Germanic; sūdor (“sweat”), the source of suor, belongs with it.[7] The root is *sweyd- (“to sweat”), also behind Ancient Greek ἱδρώς (hidrṓs, “sweat”), Sanskrit स्वेदते (svedate, “to sweat”) and Old English swāt (“sweat”), the ancestor of the English word sweat.[7][8][1]

Earliest recorded meaning

Houaiss dates the verb to the 14th century, spelt ssuar.[2] Lorenzo quotes a 14th-century Galician chronicle in which all the men ran with water all day from the great sweat they were in (da grã sudar que faziã), with a noun of the Spanish form.[9] In Portugal the corpus record begins with the Horto do Esposo, copied about 1390–1437.[10]

Semantic evolution

The Latin verb already meant both “to sweat” and, figuratively, “to toil”, and both senses passed to Portuguese.[2][11] Barbosa's dictionary of 1611 notes the figurative Latin use “to labour hard”, quoting Terence, and Bluteau (1712) quotes Livy for statues that “sweated blood”.[12][13] Vieira (1871–1874) adds walls and stones that give out moisture and the turn of phrase suar sangue, said of Christ in the garden.[14]

Modern Portuguese uses the verb for anything that oozes moisture, such as a cold bottle or a damp wall, and for winning something by hard work, as in dinheiro suado “hard-earned money”.[2][15][1] Fixed phrases include suar frio “to break out in a cold sweat”, suar as estopinhas “to make a huge effort” and dar que suar “to give a lot of trouble”.[2][16][1] The verb was borrowed as suar by the Malay of Manado and the North Moluccas.[1]
