Pronunciation

  • /ˈbweno/, [ˈbwe.no][1]

Forms

bueno (masculine singular before a noun buen, feminine buena, masculine plural buenos, feminine plural buenas, comparative mejor or más bueno, superlative buenísimo or (dated, formal) bonísimo)[1] Before a masculine singular noun it is shortened to buen (buen tiempo), as already in Old Spanish.[1][2] Old Spanish texts also have the unshifted forms bono, bonos and bonas.[3] Popular pronunciation gives güeno, recorded in the Americas.[1][4]

Etymology

It is inherited from Latin bonus (“good”), recorded as Old Spanish bueno in a charter of 1032 and in the Cantar de mio Cid.[5][6][7][1] The learned ⟨bonus⟩ is a later borrowing of the same Latin word.[1]

The same Latin word is Portuguese bom, Galician bo, Asturian bonu, Catalan bo, Occitan bon, French bon, Italian buono and Romanian bun.[5][8][1]

The Latin word is the later form of Old Latin duenos, found in the Duenos inscription, and duonus.[9][1] It goes back to *dwenos (“good”).[9][1] Its further origin is uncertain: de Vaan gives *duh₂-eno- with a question mark, and Wiktionary lists several proposed roots.[9][1] bene (“well”) and bellus (“pretty”), once a diminutive, come from the same word.[9][6]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) already uses it for “perfect of its kind”, “honourable, noble”, “brave in arms” and “favourable, lucky”, and as an epithet in the phrase el bueno de + name.[2]

Semantic evolution

In the Middle Ages bueno meant both “good of its kind” and “morally good”;[10] Alfonso de Palencia (1490) defined bonus as one who is ready to do good.[2][10] Covarrubias (1611) noted that the word is used even of bad things, as in una buena cuchillada “a fine slash”, and that buen hombre could mean a cuckold and buena mujer a whore.[11] The Diccionario de Autoridades defined it as “perfect in its kind”, and also as “upright” and “holy, virtuous”.[12] The 1884 Academy dictionary listed most of the modern senses, among them “tasty”, “big”, “healthy” and “too simple, naive”.[13]

As an interjection ¡bueno! acknowledges an order, agrees, or expresses resignation or unpleasant surprise.[14][1] In Mexico it is used to answer the telephone.[1] In Argentina, Ecuador and Uruguay el bueno is a deciding match, and in Mexico la buena.[7][15] In Honduras and El Salvador bueno can mean “sober”.[15] Among the derivatives, bonito (1517) shifted to “pretty” in the same way as Latin bellus.[6][5]
