Forms

modo m (plural modos)[1] The first record, in the 14th century, is the plural spelt moodos.[2]

Etymology

It is borrowed from Latin modus (“measure; limit; manner”), a learned word.[2][1][3] Houaiss dates it to the 14th century and Cunha to the 15th.[2][4] García de Diego calls it a learned word in both Castilian and Portuguese, beside the popular Old Spanish muedo.[5]

The Latin noun's popular outcomes are rare: Old French muef, Old Occitan mo and Catalan mou; Italian modo and Spanish modo are learned like the Portuguese word.[6] Moda “fashion” has the same source by another route, through French mode.[6][5]

In Latin the noun first meant a measured amount, a size or a limit, then moderation, rhythm and manner.[2][7] De Vaan derives it from Proto-Italic *medo- (“measure, judgement”) and Proto-Indo-European *med-o- (“measure”), the source also of Umbrian mers (“law”) and Greek μήδεα (mḗdea, “counsels, plans”).[7] Wiktionary traces it to the root Proto-Indo-European *med- (“to measure”).[1]

Semantic evolution

Barbosa's dictionary of 1611 already lists the adverbial phrases a meu modo “in my way”, de nenhum modo “in no way” and de outro modo “otherwise”.[8] Bluteau gives maneira “manner” as its meaning, and his book of synonyms adds comedimento, cortesia, brandura and modéstia, the sense of restraint and good manners.[9][10] Morais (1813) has the philosophical sense, the mode of being of a substance, as well as modo de vida “way of life, occupation”, “fashion” and “state, disposition”.[11] The musical sense, the order of tones and semitones in a scale, is recorded from the 18th century.[4] Vieira (1871) adds the terms of logic, such as the modes of the syllogism.[12]

In the sense of good manners the word is mostly used in the plural, modos; in Rio Grande do Sul people and animals are said to have bons modos or maus modos.[13][14]
