Pronunciation

Forms

legal m or f (masculine and feminine plural legales)[1] The earliest Spanish records have the plural legals (Navarre, 1297).[2] The DEMel lists the Leonese leygales (1282) and leygal (before 1300, Fuero de Salamanca) under a separate lemma.[2] Juan Fernández de Heredia also writes legual in his translation of Thucydides (c. 1384–1396).[3]

Etymology

It is a learned borrowing, borrowed from Latin lēgālis (“of or concerned with law”).[4][1][5][6] The Latin adjective is formed lēx (“law”) + -ālis.[7][1][8]

The same Latin word was inherited as leal “loyal, faithful”, recorded from the earliest texts and the Cid on.[5][6][1] García de Diego also lists Old Aragonese leyal and calls this word a learned form.[9] Corominas holds that the popular forms Portuguese leal, Catalan lleial and Occitan leial are no learned words, against Meyer-Lübke's view.[5][10] The learned word exists beside them in legal, legal and French légal, while French loyal is the inherited form.[11][12][13]

The Latin noun goes back to Proto-Italic *lēg-, which de Vaan reads as a “collection” of rules; whether the root noun already existed in Proto-Indo-European is uncertain for lack of precise cognates.[14]

Earliest recorded meaning

The DEMel's first records are the plural legals in political documents of Navarre of 1297.[2] The earliest hits of the CDH, of 1240 and 1268, are Latin texts.[3] In the late 14th century Juan Fernández de Heredia uses the word of the religious law of the Old Testament: el sacerdote legal antigo deuia prender muller virgen “the priest of the old Law had to take a virgin as wife”.[3] Corominas, who dates the word to about 1520, notes that it is the learned doublet of leal.[5][6]

Semantic evolution

In the 15th and 16th centuries the word stood close to leal: Nebrija's Latin–Spanish dictionary of 1492 glosses Latin legalis as “belonging to the law, or loyal”.[15] Covarrubias (1611) gives escriuano legal, a notary who performs his office according to the law, and in Mexico City in 1571 a notary is to be fiel y legal “faithful and lawful”.[16][17]

The Diccionario de Autoridades separates the sense “of or according to the law” from “truthful, punctual and faithful in one's duty”, and the Academy kept both through the 19th century.[18][19] Terreros equates the word with leal, fiel and bueno.[20] The 1884 edition was the first to give its etymology, and the 1899 edition added the phrase medicina legal.[21][22]

In colloquial Spanish of Spain a tipo legal is a loyal, reliable person, a use also found in marginal slang with ir de legal “to act honestly with one's friends”.[4][23][24] In Nicaragua, Panama, Peru, Cuba, Ecuador and Bolivia it means “great, excellent”, and in El Salvador “easy” of a thing.[25] Brazilian Portuguese has the same colloquial praise word.[11]
