Proto-Germanic *un-

Reconstruction

Wiktionary reconstructs the prefix *un- for Proto-West Germanic.[1]

Etymology

It is inherited from Proto-Germanic *un- (“un-, not”),[1][2] which Köbler lists with Gothic, Old Norse and all the West Germanic languages,[2] and Boutkan and Siebinga set up the same Proto-Germanic prefix behind Proto-Frisian *un-.[3]

Morphology

A negative prefix, used before adjectives and nouns,[4][3] and in Old High German also before verbs.[5]

Evidence

The prefix is found in all the West Germanic languages: Old English un-,[6] Old Frisian un-,[4] Old Saxon un-,[7] Old Dutch un-[8] and Old High German un-.[5] Old Frisian also has a by-form ⟨on-⟩, which Boutkan and Siebinga explain by the Old West Frisian variant ⟨o⟩ of ⟨u⟩ before nasals.[3] De Vaan finds the prefix in West Flemish ⟨uival⟩ "unfortunate, disliked", which matches German Unfall and reflects an Old Franconian *un-fala-; he reconstructs *unfal- > *ūfal-, so that in this variant the nasal was lost before ⟨f⟩ and the prefix was not restored, as it otherwise was.[9] He takes the form for a relic of a regular nasal loss, which need not be explained by a Proto-Frisian substratum.[9]

Meanings

  1. not, un- (negative prefix)[1][3]

Derivatives

  • *unebn "uneven, not level", which Wiktionary reconstructs;[10] Old English and Old Saxon have the negated adjective.[11][12]
  • *unhiurī "unpleasant", which Wiktionary reconstructs;[13] Old Saxon has it.[12]

Reflexes

  • Old English: un- (“un-”)[6]
  • Old Frisian: un- (“un-”)[4]
  • Old Saxon: un- (“un-”)[12]
  • Old Dutch: un- (“un-”)[8]
  • Old High German: un- (“un-, in-”)[5]
