Forms

einn num, pron, adj (feminine ein, neuter eitt)[1][2] Runic in on the Norwegian stone N 184[3] and ain on Swedish Viking Age stones.[4]

Etymology

It is inherited from Proto-Germanic *ainaz (“one”),[5][6] from Proto-Indo-European *óynos.[6] The numeral is shared by all the Germanic languages: Gothic 𐌰𐌹𐌽𐍃 (ains), Old English ān, Old Frisian ān, Old Saxon ēn and Old High German ein.[5][7]

Outside Germanic it corresponds to Latin ūnus, Old Irish óen and Lithuanian víenas, and to Ancient Greek οἴνη (oínē, “the one on a die”).[7][8][9] Feist analyses the Indo-European form as a stem *oi- with the suffix *-no-.[8] Ásgeir Blöndal Magnússon takes it as probably formed from the pronominal stem of Gothic 𐌹𐍃 (is, “he”) and of the Norse relative particle es.[9] Jóhannesson puts it under the same stem.[10]

Norse speakers lent it to Finnish, where it became aina (“always”).[11]

Earliest recorded meaning

Menota dates the word first on the Norwegian runestone N 184 of 980–1015, whose inscription ends Einn er Guð “God is one”.[12][3] The first dated manuscript records, of about 1200 in ONP, are in the sense “a certain”: Aɴa hét spakona ein “There was a prophetess named Anna”, in the Icelandic Homily Book.[13]

Semantic evolution

From the numeral “one” the word took the senses “the same” and “a certain, some”, and in the plural “some”, with numbers “about”.[14][1] ONP marks a use near an indefinite article “a” as uncertain, though it is its largest group of citations.[13] After a negation it means “any”.[14] Placed after its noun it means “alone, only”: vín eitt “wine only”.[14][1] The genitive plural einna before a superlative means “by far”.[14] In the Christian vocabulary it renders Latin solus of God.[15]

The word continues as Icelandic einn and Faroese ein, and Swedish en and Danish en.[11][9]
