Pronunciation

  • /leˈal/, [leˈal][1]

Forms

leal m or f (masculine and feminine plural leales)[1] Old Spanish also wrote leyal and leial;[2][3] leyal is the old Aragonese form.[2][3]

Etymology

It is inherited from Latin lēgālis (“of the law, legal”).[4][5][6][1] Corominas sees no reason to treat it as a learned word, as Meyer-Lübke did; the learned doublet is legal, recorded about 1520.[4][7] The Latin /g/ between vowels was lost.[8]

The same Latin word is Portuguese leal, Galician leal, Asturian lleal, Catalan lleial, Occitan leial and French loyal, the last first recorded as leial in 1080.[3][9][10][4] Italian leale was borrowed from Old French.[7]

The Latin adjective is formed from lēx (“law”) and the suffix -ālis.[11][1] De Vaan reconstructs Proto-Italic *lēg- for the noun, and gives Proto-Indo-European *lēǵ- (“collection”) with a question mark.[12]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) uses it as a fixed epithet, el Canpeador leal “the loyal Campeador”, and of a man of Burgos.[13][14] The Liber Regum (c. 1194–1211) says of King Josiah fo buen rei e leial “he was a good and loyal king”.[13][15]

Semantic evolution

Latin lēgālis meant “of the law”; in Spanish the word moved to the loyalty owed to a lord, a fellow man or God.[16][17] Berceo used it loosely for anything good or pleasing, even of the songs of birds.[18] The legal sense survived for a while: Terreros noted that in old Castilian leal meant “just, lawful”, and Salvá marked the senses “legal” and “upright, firm” as obsolete.[19][20]

Covarrubias in 1611 explained that it is said of an inferior to a superior, as of a vassal, or between equals, as of a friend, and that it is the opposite of “traitor”; he quoted the proverb No es la vida del leal, mas de quanto quiere el traydor “the loyal man lives only as long as the traitor wishes”.[21] Autoridades added De los leales se hinchen los hospitales “the hospitals are filled with the loyal”, on how badly merit is rewarded.[22] The Academy's 1843 edition first applied it to animals such as dogs and horses, and to mounts that are not vicious.[23] In the Americas it was used from 1535 in the notarial formula leal saber y entender “to the best of one's knowledge”.[24]
