Forms

mudo (feminine muda, masculine plural mudos, feminine plural mudas, not comparable)[1]

Etymology

It is inherited from Latin mūtus (“dumb, speechless”), written Old Galician-Portuguese mudo in the oldest texts.[2][3][4][1] Houaiss dates the adjective to the 13th century and its use as a noun to the 15th.[2]

The same Latin word is Galician mudo, Spanish mudo, Catalan mut, Italian muto and Romanian mut.[5][6][1] French muet is a diminutive of Old French mu, the old adjective, which went out of use in the 16th century.[7][8]

For de Vaan the Latin word meant at first one who can utter nothing but /muː/, from an imitative root also found in mūgiō (“to low”), with cognates such as मूक (mū́ka, “dumb”).[9][1] Wiktionary sets up Proto-Indo-European *mewH- (“to mutter, say mu”).[1] Bluteau, in 1712, already related the word to Latin mutire “to mutter”, saying that mutes who wish to speak usually utter /mu/.[10]

Earliest recorded meaning

The Cantigas de Santa Maria use the word of animals, as bestias mudas “the dumb beasts”, and of people: a man who lay çego e ar mudo sen fala “blind and dumb, without speech”, and one who era sordo e mudo “was deaf and dumb” until the Virgin healed him.[3] The Cancioneiro da Ajuda glosses it “without speech”.[3]

Semantic evolution

Already in the cantigas a lover says he goes about mudo, silent for love.[11] The Crónica Geral tells of a man called Pero Mudo because he stammered.[3] Morais (1789) records a night muda de vento, without wind, a letra muda, a consonant whose name holds no vowel, and a representação muda without speech.[12] Later senses are a telephone or a set that gives no sound, a theatre scene without dialogue, and, in the 20th century, the silent cinema, cinema mudo.[2][13] Silva Bastos and the DLP also record mudo as the name of a popular game.[14][15]

Timeline

  • 13th century – as bestias mudas and sordo e mudo in the Cantigas de Santa Maria.[3][2]
  • 1344 – the chronicle the DDGM cites as Cr. 1344 explains the name of Pero Mudo.[3]
  • c. 1430 – the Horto do Esposo uses the word.[16]
  • 15th century – first use as a noun, “a mute”.[2]
  • 1572 – Camões, in canto V of Os Lusíadas, describes a people quasi mudo to the Portuguese.[17]
  • 1712–1728 – Bluteau relates the word to Latin mutire.[10]
  • 1789 – Morais records letra muda and noite muda de vento.[12]
