Forms

alguno (feminine alguna, masculine plural algunos, feminine plural algunas)[1] Old Spanish also wrote algund and algunt beside the shortened algún; rarer old spellings are algum, adgún, alcuno and alkuna.[2][3] Until the 16th century algún could also stand before a feminine noun beginning with a vowel (algún obra), and in the 13th century the full form could precede a noun (alguno omne).[2]

Etymology

It is inherited from Vulgar Latin *alicunus, a contraction of Latin aliquis (“someone, anyone”) with unus (“one”).[4][5][6][1] The Vulgar Latin form is not attested;[1] Wiktionary notes that it is first found in Old French, in the 10th century.[1]

The same compound is Portuguese algum, Galician algún, Catalan algú, French aucun and Italian alcuno.[7][1][8] Because the word was so often used with a negation, alcun and its Old Italian counterpart came to mean “none”, as the French word does today.[7][9] Portuguese has an early trace of the form in a Latin document of 897.[10]

The Latin pronoun is formed from the stem of alius (“other”) and quis (“who”);[11][1] de Vaan suggests that the first part may be a shortening of that word, which goes back to Proto-Indo-European *h₂el-io- (“another”).[12]

Corominas argues that alguien is not the Latin accusative aliquem, which would have given *algue, but a 15th-century remodelling of this word under the influence of quien.[4][5] algo continues the neuter aliquod.[4]

Earliest recorded meaning

Corominas dates the full form to 1077 and the shortened algún to the Cantar de mio Cid (c. 1140).[4][5] In the Cid it is already an indefinite word for an unspecified person or thing, and can be used alone in the plural (algunos, “some people”, line 3116).[13][14]

Semantic evolution

Until the end of the Middle Ages alguno served both as adjective and as pronoun “someone”, since alguien does not appear in Castile before the 15th century; the new pronoun was stressed alguién until the 17th century, when Calderón already has the modern stress.[4][5] Alfonso X's prose uses the word for one or several unspecified things and also in the sense “a certain amount, a fair amount” (algun tiempo).[15]

Placed after the noun in a negative sentence, alguno means “none, no … at all” (sin duda alguna); Domínguez described this use in 1846, and Salvá noted that in the old language it could mean ninguno even before the noun.[16][17][6] The Academy's dictionary of 1770 recorded an old legal sense, “valid”, as opposed to ninguno “null”, with a quotation from the Leyes del Estilo.[18] Cuervo's dictionary of 1886 analysed the word's uses in detail, from the fully indefinite to the negative and the phrase alguno que otro.[19]

  • 1726 – the Diccionario de Autoridades explains it as a compound of aliquis and unus.[23]
  • 1884 – the Academy's dictionary gives the etymology and the senses “someone” and “a fair amount”.[24]
