Reconstruction

Wiktionary reconstructs *kannijan "to know, to be aware of".[1]

Etymology

It is inherited from Proto-Germanic *kannijaną (“to make known”),[2][3] which Kroonen cites as *kannjan-, Orel as *kannjanan and EWA as *kannii̯e/a-.[3][4][5] EWA explains it as a causative of the preterite-present *kann, *kunnum "to know" of Proto-Germanic, properly "to make someone know something";[5] Ringe and Taylor reconstruct that verb as Proto-West Germanic *kunnan.[6]

Morphology

A weak verb of class I.[5][7][8]

Evidence

The simple verb is attested as Old English cennan (“to appoint, to declare”),[9] Old Frisian kenna, beside kanna,[10] and Old Dutch kennen, recorded in the Old Low Franconian psalms of the 10th century.[11] Old Saxon has only the prefixed Old Saxon andkennian (“to recognize, to acknowledge”), common in the Heliand;[12] Köbler sets up an unrecorded simple verb, which Holthausen placed in the minor texts but which cannot be found there.[13] Old High German too has the verb only with prefixes, as in Old High German bikennen.[14][5]

Competing analyses

Old English cennan has a homonym "to beget, to bring forth", which Holthausen and Köbler treat as a separate verb.[15][9] Kroonen sets up a separate Proto-Germanic *kanjan- "to bring forth" for it, and takes Old Norse kenna (“to father (a child)”) for a loan from Old English;[3] Wiktionary likewise has a separate *kannjan "to beget, to bring forth", from Proto-Germanic *kanjaną.[16] Ringe and Taylor derive Old English cennan (“to beget”) from pre-Old English *kąnnijąn.[17] Orel separates the two verbs as *kannjanan I and II, but reports Schröder's and Güntert's view that at a deeper level they are one.[4] Old Saxon has the "beget" verb in the participle kennit in the Heliand.[13]

Meanings

  1. to know, to be aware of[1]

Kroonen and Orel give the Proto-Germanic verb the meaning "to make known".[3][4] Old English used the verb for "to determine, to appoint, to choose, to declare",[9] Old Frisian for "to know, to recognize, to decide, to confess",[10] and Old Dutch for "to know, to understand".[8]

Derivatives

  • *bikannijan "to get to know, to recognize", which Wiktionary reconstructs;[18] Old High German bikennen is recorded from the 8th century,[5] and Old Frisian has bikenna.[10]
  • *unþakannijan "to deny knowledge of, to disavow", which Wiktionary reconstructs;[19] Old Frisian has undkenna,[10] and Old Saxon andkennian.[12]

Reflexes

  • Old English: cennan (“to determine, to appoint, to choose, to declare”)[9]
  • Old Frisian: kenna (“to know, to recognize, to decide, to confess”)[10]
  • Old Dutch: kennen (“to know”)[11]
