Reconstruction

The infinitive is *kannijaną in Wiktionary,[1] *kannjanan in Orel (his *kannjanan I)[2] and *kannjan in Köbler;[3] Kroonen cites the stem *kannjan-.[4]

Etymology

It is from Proto-Indo-European *ǵneh₃- (“to know”), the root of *kunnaną "to know",[5][3] and is formed from that verb with the causative suffix *-janą.[1]

Morphology

A class I weak verb,[6] the causative of *kunnan- "to know, can".[4][2][7] Kroonen explains the geminate of *kunnan- from the singular root of the preterite-present,[5] third person singular *kanne, plural *kunnunþ, from a quasi-PIE *ǵon-n-h₁-e, *ǵn̥-n-h₁-n̥t.[8]

Evidence

The verb is attested in all three branches: Gothic 𐌺𐌰𐌽𐌽𐌾𐌰𐌽 (kannjan) in Gothic, Old Norse kenna in Old Norse, and Old English cennan, Old Frisian kenna, Old Saxon ant-kennian and Old High German ar-kennan in West Germanic.[4][2] The Gothic verb occurs at Ephesians 1:9.[6]

Competing analyses

Old English cennan also means "to beget, to bring forth".[9] Kroonen separates this verb as *kanjan-, a causative to Proto-Indo-European *ǵenh₁-, and takes Old Norse kenna (“to father a child”) as a loan from Old English;[4] Orel sets it up as *kannjanan II and reports Schröder's and Güntert's view that at a deeper level it is the same word.[10] De Vries too cites Schröder: the roots for "to know" and "to beget" can hardly be separated.[11] Bammesberger writes the verb for "to beget" *kann-ijan-, as a causative to *ǵenə-.[12]

Meanings

  1. to make known[4][1]
  2. to know[3]

Old Norse used the verb for "to teach" and "to know, to recognise",[2][4] Old English for "to choose, to prove, to declare",[4] and Old Saxon for "to perceive" and Old High German for "to recognise".[4]

Derivatives

  • *kanninʒō "teaching, recognition" in Orel.[13]
