Forms
un m (feminine una, masculine plural uns, feminine plural unes)[1] A reduced form u, often written hu in old texts, is used when the number names a place in a series (l’u de maig, vint-i-u) and in tot és u; in Valencia it is the usual indefinite pronoun.[2][3]
Etymology
It is inherited from Latin ūnus (“one”).[2][4][5][6][1] At first only a numeral, it also became the indefinite article, with the plurals ⟨uns⟩ and ⟨unes⟩, as in all the Romance languages.[2]
The same Latin word is Occitan un, Spanish uno, Portuguese um, Italian uno and Romanian unu.[1][7]
The Latin word continues Old Latin oinos (the accusative ⟨oino⟩ is in the epitaph of a Scipio), from Proto-Italic *oinos and Proto-Indo-European *h₁óynos (“one, single”); it is related to the English word one.[8][1] Among its cognates are Ancient Greek οἰνή (oinḗ, “the one on a die”) and Old English ān.[8][1]
Earliest recorded meaning
CICA's first record is in the Llibre dels judicis, of the first half of the 12th century.[9] The DCVB's oldest quotation is from the Homilies d'Organyà, and Coromines dates the word to the beginnings of the language.[4][2]
Semantic evolution
Llull uses un both as the cardinal number, the unit of which all other numbers are made, and as the indefinite article before a noun not mentioned before, as in the Fèlix (un caveller cassava).[10] As a pronoun meaning one and the same, it appears in Llull's Contemplació (Déu és un en trinitat), and Coromines quotes Maragall's line about the Catalans who will one day be tots uns.[2] Faraudo records it for 'sole, only' and for one of two, set against the other, as in the Curial.[11]
The reduced pronoun u wavered with un in the 14th and 15th centuries, influenced by algú beside algun: Bernat Metge's Somni has both.[2] Lacavalleria (1696) still gives hu as the normal pronoun, while Belvitges (1805) and Labèrnia admit it only in tot és u.[2] Valencian kept u as the indefinite pronoun, as Ausiàs March already shows and Martí Gadea's dictionary of 1891 records.[2] Before a numeral the plural means 'about' (uns tres dies).[4][6]
