Reconstruction

Ringe and Taylor reconstruct Proto-West Germanic *bi ~ *bī,[1] and Wiktionary has *bī.[2]

Etymology

It is inherited from Proto-Germanic *bi (“around, by, near”),[1][3] which Orel writes *ƀi.[3] Ringe and Taylor hold that word-final vowels of stressed monosyllables were lengthened in Proto-West Germanic, though the examples are few, and they give this word beside *nū "now" and *swā "so".[1] Since Old Norse lengthened such vowels too, even vowels that became final only in its own history, they take the Norse and West Germanic changes for parallel innovations.[1] Orel likewise speaks of a secondary lengthening of the stressed final vowel in West Germanic.[3] EWA sets up a weakly stressed *bi and a strongly stressed, secondarily lengthened *bī already for Proto-Germanic,[4] and Boutkan and Siebinga say that the monosyllable could be lengthened under stress in Northwest Germanic or weakened under weak stress.[5]

Morphology

An adverb and preposition, also used as a prefix.[6][4] Fulk explains the two vowels by stress: like prepositions, prefixes were stressed in nouns and unstressed in verbs, and by Prokosch's law a preposition ending in a vowel was lengthened when stressed, a length that could then spread to the stressed prefixes.[7] So Old English has be or, stressed, bī, and beside verbs such as begān (“to traverse”) stand nouns such as bīgenga (“inhabitant”) and bīnama (“pronoun”), while Gothic generalised the short vowel.[7] In Old High German the stressed prefix of nominal compounds could stay bi-, while the unstressed prefix of verbs became be-, throughout in Notker and occasionally earlier.[4]

Evidence

Ringe and Taylor cite Old Frisian bī, Old English be ~ bī, Old Saxon be ~ bī, and Old High German bi ~ bī.[1] The Wachtendonck psalms of the 9th century have Old Dutch bi,[8] and ONW records it in Williram's commentary on the Song of Songs of about 1100.[9] Findell notes that the runic inscription ⟨bi⟩ on the Hüfingen III fibula, if it is a word at all, could be the adverb or preposition of Old High German or the prefix, after Düwel and Pieper; its meaning is unclear.[10] Outside West Germanic, Boutkan and Siebinga find the word missing in North Germanic,[5] whereas EWA cites a runic Norse ⟨bi⟩ on the spear shaft of Kragehul in Denmark, of the 6th century.[4]

Meanings

  1. by, near[1][2]
  2. around[1][2]
  3. at[2]

Old High German also used the preposition in senses of time, "within, during", of cause, "because of", and of manner, "according to, instead of".[4] Old Frisian also had "during", "according to" and "at the cost of".[5]

Derivatives

  • Fulk derives Old English blinnan (“to cease”) from West Germanic *bi-linnan, and būtan (“except”) and Old Saxon būtan from *bi-ūtan.[7]
  • De Vaan finds the adverbs formed from *bī and an adverb beginning with a vowel, Dutch binnen (“inside”), buiten (“outside”) and boven (“above”), throughout the Dutch area.[11]

Reflexes

  • Old English: bī (“by, at, with, to, concerning”)[12]
  • Old Frisian: bī (“by, at, beside, together with, during, according to”)[13]
  • Old Saxon: bī (“by, at, through, with, because of, during”)[14]
  • Old Dutch: bī (“by, near”)[9]
  • Old High German: bī (“near; by, beside, at, during, because of”)[4]
