Pronunciation

Forms

sudar (first-person singular present sudo, first-person singular preterite sudé, past participle sudado)[1] Old Spanish also had suar, in Abraham of Toledo's Moamín (1250) and Alfonso X's Lapidario.[2][3]

Etymology

It is inherited from Latin sūdāre (“to sweat”).[4][5][1] Corominas calls it general at every period and common to all the western Romance languages.[4]

The same Latin verb is Portuguese suar, Catalan suar, French suer, Occitan susar and Italian sudare.[6][7] In his Catalan dictionary Corominas explains the forms as regular: Latin /d/ stayed in Italian, Spanish and Gascon, became /z/ in Occitan and was lost in French, Portuguese and Catalan.[8] García de Diego takes a different view: for him the Spanish verb is a learned form, and the popular outcome is suar of Old and dialectal Spanish, which agrees with Portuguese, Galician and Catalan.[7]

The Latin verb was probably formed from a noun *swoyd-o- (“sweat”), the source also of Old English swāt (“sweat”) and Old High German sweiz, from the root Proto-Indo-European *sweyd- (“to sweat”).[9][1] The noun sūdor gave Spanish sudor.[4]

Earliest recorded meaning

Corominas's first record is Berceo.[4] In the Vida de San Millán (c. 1230, known from an 18th-century copy) the verb already has a figurative turn: the two saints who help in battle did not want to take their pay for nothing, but primero la quisieron merecer e sudar “first wanted to earn it and sweat for it”.[2][10] In the literal sense it appears in the Lapidario of Alfonso X, of a stone that makes the one who looks at it sweat.[3]

Semantic evolution

Autoridades (1739) records the verb for sweating, for giving something up unwillingly, for toiling, and figuratively for trees and plants that exude drops of sap.[11] The 1843 dictionary has the proverb lo que otro suda, a mí poco me dura, of cast-off clothes that soon wear out.[12][13] The current dictionary also has damp things that let water through their pores, such as a wall or a porous jug, and the vulgar Spanish sudársela “not to care at all”.[5][1]

In the Dominican Republic sudar a newborn is to hold it in one's arms so that it takes in warmth and, by popular belief, the holder's good qualities.[14][15] In Judeo-Spanish the verb also means “to calm down” after a fit of anger or a long sulk.[16]
