Pronunciation
- /ˈmudo/, [ˈmu.ð̞o][1]
Forms
mudo (feminine muda, masculine plural mudos, feminine plural mudas)[1]
Etymology
It is inherited from Old Spanish mudo, inherited from Latin mūtus (“dumb, silent”).[2][3][4][1] The Latin /t/ between vowels was voiced to /d/.[1][5] Corominas notes that the word has been in general use in every period and is common to all the Romance languages.[2]
The same Latin word is Portuguese mudo, Galician mudo, Asturian mudu, Catalan mut, Occitan mut, Italian muto and Romanian mut.[6][7][1] French muet is a derivative of Old French mu, the old French outcome of the Latin word.[8][1]
De Vaan explains the Latin adjective as describing one who can say nothing but mū, from Proto-Indo-European *mū̆-to-, and compares Sanskrit मूक (mū́ka, “dumb”) and Ancient Greek μυνδός (mundós, “dumb”).[9][1] The OLD likewise calls it onomatopoeic and first records it of animals, as in Naevius's “dumb quadrupeds”.[10]
Earliest recorded meaning
The first record is in the Cantar de mio Cid (c. 1140), as the nickname of one of the Cid's knights: Pero Mudo, varón que tanto callas “Pero the Mute, you who keep so silent” (lines 3302, 3310).[11][3][12] DEMel's first record in a document is the Fuero de Madrid (1158–1202).[12] In Alfonso X's laws (1256–1300) it has the full sense “unable to speak”, beside sordos “deaf”.[13]
Semantic evolution
Alfonso X's Judizios (1254) already used mudos as a term of astrology for the signs Cancer, Scorpio and Pisces.[13] In the Americas Fernández de Oviedo (1549) wrote of little dogs that were mudos because they could not bark.[14]
The Diccionario de Autoridades (1734) gave the person unable to speak, “very quiet” by extension, the astrological signs and the grammatical sense of a consonant letter.[15] The DLE now adds the phonetic sense “plosive” and the letter that is written but not pronounced, such as the h of hombre.[4] In Ecuador, Guatemala and north-west Argentina mudo means “stupid”; in El Salvador it is a thief's hidden pistol.[16][4]
