Pronunciation

  • Brazil: /suˈɔʁ/, [suˈɔh], /ˈswɔʁ/[1]
  • São-Paulo: /suˈɔɾ/, /ˈswɔɾ/[1]
  • Rio-de-Janeiro: /suˈɔʁ/, [suˈɔχ], /ˈswɔʁ/[1]

Forms

suor m (plural suores)[1] Medieval texts also write suur and sudor.[2][3][4]

Etymology

It is inherited from Latin sūdor (“sweat”), written Old Galician-Portuguese suor, Old Galician-Portuguese suur and Old Galician-Portuguese sudor in medieval texts.[3][2][1][5] The long Latin ō gave a closed /o/, which Nunes says the word once had in the whole country and still keeps in the Algarve; the standard language now has an open vowel.[6][7][8][3]

The same Latin word is Galician suor, Spanish sudor, Catalan suor, French sueur, Italian sudore and Romanian sudoare.[9][1]

The Latin noun is formed from sūdō (“to sweat”).[10] De Vaan reconstructs a collective Proto-Indo-European *sueid-s- (“sweat”) and compares Welsh chwys (“sweat”), Ancient Greek ἱδρώς (hidrṓs, “sweat”) and Sanskrit and Avestan words for sweat.[11] Wiktionary traces it to the root *sweyd- (“to sweat”), whence also Old English swāt, the ancestor of the English word sweat.[1]

Earliest recorded meaning

The Crónica of 1344 has do poo e da suor “of the dust and the sweat”, and a Galician chronicle has the same phrase as do poo et da suur; in both the noun takes the feminine article.[4]

Semantic evolution

Cardoso (1569) simply glosses it as Latin sudor.[12] Morais (1813) adds the figurative sense “toil”, with the biblical phrase ganharás o pão com o suor de teu rosto “you will earn your bread by the sweat of your brow”, and the phrases suores de morte and estar em suores frios, “to be in great distress”.[13] The original Aulete records suor de sangue for any liquid coming through the pores, and quotes Camões for the toil of the servants.[14] Today the word also means the fruit of long labour.[3][15] In Paraíba suor de alambique “sweat of the still” is sugar-cane spirit.[16]
