Pronunciation

  • Russia, Southern: [aˈdʲin][1]

Forms

оди́н (odín) m (feminine одна́, neuter одно́)[1]

Etymology

It is inherited from Old East Slavic одинъ (odinŭ), from Proto-Slavic *edinъ (“one”).[1][2][3] The other Slavic languages have Ukrainian один (odyn), Belarusian адзін (adzin), Old Church Slavonic ѥдинъ (jedinŭ) beside ѥдьнъ (jedĭnŭ), Bulgarian един (edin), Serbo-Croatian jedan, Czech jeden and Polish jeden, with jedyny (“only”).[2][4][3] The shortening of ⟨-и-⟩ to a jer, which gives the forms одного (odnogo) and одна (odna), probably happened in the separate languages rather than in Proto-Slavic.[2] The form единый is a borrowing from Church Slavonic.[2]

Vasmer takes the word to be probably a compound of *ed- and *inъ (“one”) (see иной).[2] The first part is an emphatic pronominal element of the Indo-European stem *e- (compare этот), the same as in Latin ecce (“look, here”) and id (“it”);[2][4] the second goes back to Proto-Indo-European *h₁óy(H)nos (“one”), the source of Lithuanian vienas, Latvian viens, Old Prussian ains, Old Latin oinos (ūnus), Ancient Greek οἴνη (oínē, “the ace on a die”) and Old Irish óen.[2][4][1] Derksen and Wiktionary reconstruct *h₁edʰ-(H)iH-no-.[3][1] A link with Old Church Slavonic ѥда (jeda, “whether”) is less likely, according to Vasmer.[2]

одинец, an old boar that lives apart from the herd, belongs here.[2]

Earliest recorded meaning

The Izbornik of 1076 has „Лѹче бо ѥ ‹о›динъ нежели тысѧшти” “for one is better than a thousand”, translating Greek εἷς (heîs).[5] Chernykh dates the word in Old Russian from the 11th century.[4]

Semantic evolution

Already in the 12th and 13th centuries the numeral also meant “alone” („а кн҃зь одiнъ” “but the prince was alone”, in a Novgorod chronicle) and “the same” (both books copied „одиномь лѣ(т)” “in one year”, in a scribe's note of the late 12th century).[5] In the Lay of Igor's Campaign it means “only, single”: „Одинъ братъ, одинъ свѣтъ свѣтлыи — ты, Игорю!” “my only brother, my one bright light, you, Igor!”.[6] Sreznevsky records “first”, “the only”, “lonely” and “alike” too.[7]

In the modern language the word is also an indefinite pronoun “a certain, some” and a limiting word “nothing but”, as in одни неприятности “nothing but trouble”.[8]

Timeline

  • 1076 – одинъ “one” in the Izbornik of 1076.[5]
  • late 12th century – одиномь лѣ(т) “in one year” in a scribe's note.[5]
  • 1229 – ѡднемь послухомь “by one witness” in a Smolensk treaty, in a copy of 1277–1279.[5]
  • 1282 – ѡдиномь ѡкомь слепъ “blind in one eye” in a Prologue.[5]
