Forms

asno m (plural asnos)[1] A variant asnho is recorded in 1269.[2][3]

Etymology

It is inherited from Latin asinus (“ass, donkey”), written Old Galician-Portuguese asno in the oldest texts.[4][3][2][1] The unstressed vowel of the second syllable was lost.[5] The same Latin word is Galician asno, Spanish asno, Catalan ase, French âne, Italian asino, Sardinian ainu, Aromanian asin and Romanian asin.[6][7][1]

The Latin word is itself a loan: de Vaan notes that its intervocalic /s/, which was not rhotacised, points to a recent borrowing, and that most Indo-European words for the ass are loanwords.[8] He rejects a common source *os(o)no- with Ancient Greek ὄνος (ónos), and suggests that Hieroglyphic Luwian tarkasna- and Sumerian anšu may contain the base of the Greek and Latin words.[8] Wiktionary similarly thinks of a substrate language of Asia Minor.[9]

Earliest recorded meaning

A Latin text of 1209 already writes uno asno “one ass”, with the Romance form inside the Latin.[2] The first Galician-Portuguese records are a text of 1228, Do asno ou de asna iij dñ. “for an ass or a she-ass three deniers”, and a regulation of fairs of 1269 that has asnho.[10][2] The sense in all of them is the animal, as a beast of burden and an object of trade.[10][2]

Semantic evolution

The Miragres de Santiago use the word several times (enprestoche aqueste meu asno “I lend you this ass of mine”), and a cantiga of escarnho by Johan de Gaia mocks a knight who “was sold like an ass at the market” (come asno no mercado / se vendeu un cavaleiro).[10] Morais (1789) records the figurative sense “dolt, very foolish person”, and Bluteau (1712) already describes the animal as lazy and dull-witted, but hard-working and patient.[11][12] The old Caldas Aulete has ficar com cara de asno “to look like an ass”, to realise one has been cheated.[13] Houaiss and Aurélio define asno by referring to jumento and burro.[4][5] It is also the name of a fish, the cangulo-da-parede.[4][14]
