From the same root
Pronunciation
Forms
legal m or f (plural legais, comparable, comparative mais legal, superlative o mais legal or legalíssimo, diminutive legalzinho, augmentative legalzão)[1]
Etymology
It is borrowed from Latin lēgālis (“of the law, legal”), from lēx (“law”) and the suffix -ālis.[2][3][1][4] It is the learned doublet of leal “loyal”, the popular outcome of the same Latin word.[2][5][1]
Other Romance languages have the same pair: Spanish legal and Spanish leal, French légal and French loyal, Italian legale and Italian leale.[6][7][8]
De Vaan reconstructs a Proto-Italic root noun *lēg- (“law”), perhaps a “collection” of rules, and doubts that it existed in Proto-Indo-European.[9]
Earliest recorded meaning
Houaiss dates the word to the 13th century and Cunha to the 15th, with the sense “of the law, according to the law”.[2][3]
Semantic evolution
Bluteau's dictionary (1712–1728) defines it as concerning or conforming to the laws, and explains parentesco legal as the kinship created by adoption.[10] Morais (1789) gives “according to the laws” and “introduced by law”.[11] Vieira adds dia legal, a day reckoned from eve to eve.[12] The DLP also records a religious sense, “of the law of Moses”.[13]
In informal Brazilian Portuguese the word took the sense “in order, all right” and then became an all-purpose word of approval, “good, nice, cool”, said of people and things alike; it is also an adverb, “very well”.[2][14][15][1] It takes the augmentative legalzão and the diminutive legalzinho.[1] Estraviz records the Brazilian sense “excellent” in Galician too.[16]
