Pronunciation

Forms

liso (feminine lisa, masculine plural lisos, feminine plural lisas, diminutive lisinho)[1] The spelling lizo was used beside liso from the 18th century: Bluteau, Feijó and Morais head the word liso, ou lizo.[2][3][4]

Etymology

According to Houaiss it is inherited from Vulgar Latin *lisius, a word of obscure origin, perhaps an expressive creation, which is shared by the languages of Iberia, southern France, the Alps and Italy.[5] Corominas sets up the same Romance base and thinks it was probably suggested by the sound of something sliding over a smooth surface.[6][7] Cunha, Nascentes and Aurélio call it of obscure origin.[8][9][10]

Wiktionary and the DLP derive it from Ancient Greek λισσός (lissós, “smooth”).[1][11] Nascentes, in his larger dictionary of 1955, rejects the Greek word, which he says occurs only in Homer and does not fit phonetically, and prefers the Germanic origin given in Meyer-Lübke's REW, comparing German leise (“quiet, soft”).[12][13] Silva Bastos took it from Old High German lise.[12][13] Homer uses the Greek adjective of a smooth rock.[14]

The Romance words are Galician liso, Spanish liso, Catalan llis, Occitan lis, French lisse and Italian liscio.[1] In Spanish it is recorded from 1335, in Juan Ruiz, with a voiced /z/ in the old language.[6][7]

Earliest recorded meaning

Houaiss and Cunha's addenda date the first record to the 15th century, in the sense “having a flat, even surface, without roughness”.[5][8] A private letter of 1544 has the spelling lyso.[15]

Semantic evolution

Bluteau lists the senses “made smooth”, “not curly” (of hair), “without roughness to the touch” and, figuratively, “sincere, not dissembling”.[2][16] Folqman (1755) has não ser liso “not to deal sincerely”.[2][16] Morais (1789) adds “without embroidery, pleats or ornaments” of clothes and “plain” of a speech.[4]

Brazilian Portuguese made it slang for “penniless”, and the north-east has the phrase liso, leso e louco “utterly broke”.[5][10][17] Regional Brazilian senses describe cattle: in Pará a heifer that has not yet calved, in Ceará a fine red coat, in Paraíba a light colour without spots; in Rio Grande do Sul a liso is a tall glass for spirits.[5][18] In Alagoas the Lisos were the opposition party of the revolt of 1844.[5][19] In Portugal água lisa is still mineral water.[5]

  • 1716 – the spelling lizo.[5]

  • 1800s – lisura, Cunha's date for the noun.[8]
