Pronunciation

Forms

un m or n (feminine singular o, plural niște)[1] The genitive-dative forms are unui (masculine and neuter) and unei (feminine), and unor in the plural.[2] Besides niște, the plural unii, unele is used, as in Friulian.[3][2] The old feminine was ună, as in Dosoftei: „ună Dumnezeire, ună putere” “one Godhead, one power”.[4]

Etymology

It is inherited from Latin ūnus (“one”).[5][3][2][1] The Latin numeral continues Old Latin oinos, from Proto-Indo-European *h₁óynos.[1]

The word survives in all four branches: Aromanian un, Megleno-Romanian un, and Istro-Romanian un, with ur as its numeral.[5][3][6] Its Romance cognates include Italian uno, Spanish uno, Occitan un, Catalan un and French un.[5][3]

Earliest recorded meaning

Tiktin dates the first record to Neacșu's letter of 1521.[4] The Hurmuzaki Psalter, of the early 16th century, already has the word eight times.[7]

Semantic evolution

The forms un, feminine o, serve as the article and the numeral, and the longer unul, una as the pronoun;[5] Ciorănescu compares the final -a of the pronoun with that of acel.[5] In the old texts the pronoun could also stand before a noun for emphasis, meaning “the only, the sole”: Coresi writes „cine poate lăsa păcatele, fără unul Dumnezeu?” “who can forgive sins but God alone?”.[5] The feminine una used as a neuter pronoun means “something, a thing; a blow”, and it also serves as an adverb meaning “the same, level with”: te fac una cu pământul “I will flatten you”, literally “make you one with the earth”.[5][3] Ciorănescu notes that some phrases built on the word, such as unul și același “one and the same”, have exact parallels in Modern Greek.[5]

Romanian formed the verb uni “to join”, which Pușcariu instead derived from Latin unire.[5] The noun unealtă “tool” seems to come from the phrase une-alte “some and others”, according to Hasdeu, Philippide, Iordan and Tiktin, whom Ciorănescu cites.[5]

Timeline

  • 1801 – Klein's dictionary glosses Un, a with Latin unus, a, um and quidam “a certain”.[10]
