Pronunciation

  • Brazil: /leˈaw/, [leˈaʊ̯][1]
  • Portugal: /ˈljal/, [ˈljaɫ][1]
  • Portugal, Southern: /ˈlja.li/[1]

Forms

leal m or f (plural leais, comparable, comparative mais leal, superlative o mais leal or lealíssimo)[1] Old Galician-Portuguese wrote leal and leaal, plural leales; 15th-century texts have leaaes, leaees and lyall.[2][3] The spelling lial is recorded by Feijó in 1734 and by Houaiss for the coin.[4][2]

Etymology

It is inherited from Latin lēgālis (“of the law; lawful”), written Old Galician-Portuguese leal in the oldest texts.[2][5][1] It is the popular counterpart of the learned legal, from the same Latin word, which Cunha dates to the 15th century.[2][5][1]

The same Latin word is Galician leal, Spanish leal, Catalan lleial, Occitan leial and French loyal, while Italian leale is from Old French.[6][1] Old Spanish and Old Aragonese also had Old Spanish leyal, with a /j/ that broke the hiatus.[7][8]

The Latin adjective is formed from lēx (“law”) and the suffix -ālis.[9][1] Lewis & Short note that Tertullian already used it of a life lived according to the divine law;[10][11] Nascentes explains the Portuguese sense from that: a loyal person keeps the laws of probity and honour.[10][11]

Earliest recorded meaning

The word is common in the 13th-century cantigas: the Cantigas de Santa Maria call the Virgin leal e mui verdadeira “loyal and most true” and say that she protects os que lle son leaes “those who are loyal to her”, and a satirical cantiga of Afons’ Eanes do Coton has sõo eu cord’ e leal “I am sensible and loyal”.[3][12] Houaiss dates the word to the 13th century.[2] Cunha does so too, and dates lealdade and desleal to the same century.[5]

Semantic evolution

The medieval glossaries render it “faithful, devoted, true, honest”, and the Crónica Troiana uses it of a faithful husband.[3] The legal sense “in accordance with the law” survives in dictionaries but is marked as obsolete by the DLP, which also has an old sense “genuine, not counterfeit”.[2][13]

The word also named coins: a letter of 1441 from the Infante Pedro raised the value of the silver leais that King João I had minted from ten to twelve réis, and Bluteau records a copper leal struck at Goa by Afonso de Albuquerque.[14][15] Morais and Vieira assign the twelve-réis coin to João II instead.[16][17]

In European Portuguese the word is pronounced as one syllable, /ˈljal/, while Brazil keeps two, /leˈaw/.[1]

Timeline

  • 13th century – first records, in the Cantigas de Santa Maria and the satirical cantigas.[2][3]
  • 1390–1437 – the Horto do Esposo uses the word.[18]
  • 15th century – the spellings leaaes, leaees and lyall;[14] legal enters as a learned word.[2][5]
  • 1441 – the Infante Pedro revalues the coins called leais.[14]
  • 1569 – Cardoso glosses it with Latin fidelis.[19]
  • 1712–1728 – Bluteau records the copper coin of Goa.[15]
  • 1734 – Feijó gives the spelling lial.[4]
