Reconstruction
The numeral is *ainaz in Orel, Ringe and Wiktionary,[1][2][3] cited by its stem *aina- in Kroonen and Köbler.[4][5]
Etymology
It is inherited from Proto-Indo-European *h₁óynos (“one”).[3] Ringe takes it from PIE *óynos "single (?)", which is also the usual word for "one" in Italic, Celtic and probably Balto-Slavic;[2] Kroonen writes *Hoi-Hn-o-.[4]
Morphology
Ringe says the numeral was inflected like an ordinary strong adjective.[6] The inherited PIE word *sem- "one" does not survive in Germanic.[2] The negative suffixes Old Norse -a and -at of Old West Norse poetry go back to the masculine and neuter forms of "one", *aina and *ainata.[7]
Evidence
The word is attested in all three branches: Gothic 𐌰𐌹𐌽𐍃 (ains), Old Norse einn, Old English ān, Old Frisian ān, Old Saxon ēn and Old High German ein.[4] In Gothic it had not yet become an indefinite article.[8] The Finnic loan Finnish aina (“always”) and its relatives were borrowed from this word.[9][10]
Competing analyses
Kroonen calls *ainaz a West Indo-European numeral built on a root *Hoi-, which also underlies the Sanskrit word for "one", from *Hoi-ko- and the Avestan word for "one" from *Hoi-uo-; the Germanic word is identical to Latin ūnus.[4] Orel likewise equates it with Latin, Old Irish óen and Old Prussian ains, and relates it further to the Sanskrit and Avestan words and to Ancient Greek οἶος (oîos).[1] Feist split PIE *oinos into *oi- and a suffix *-no-.[11] Bammesberger counts *aina- among the words for unity in which innovation is to be expected, since the related languages show other consonants in place of its -n-.[12]
Meanings
Ringe notes that several daughters use plural forms for "some" and weak forms for "alone", and that both uses may already have existed in Proto-Germanic.[6] Old Frisian also used the word as an indefinite article and, with numerals, for "about".[13]
Derivatives
- *ainalif "eleven", with *-lif "left over";[14] Kroonen *ainalifa-.[4]
- *ainagaz "only, sole", like Latin ūnicus;[15] Orel *ainaʒaz.[16] Kroonen has *ainahan- "single", formally close to the Latin word.[4]
- Compounds: *ainafalþaz "onefold, simple",[17] *ainaugijaz "one-eyed"[18] and *ainahandijaz "one-handed".[19]
