Reconstruction

The infinitive is *kunnaną in Ringe and Wiktionary,[1][2] *kunnan in Köbler[3] and the stem *kunnan- in Kroonen.[4] Orel heads it by the 3rd singular *kanna,[5] Seebold by KANN.[6] Ringe gives the principal parts *kunnaną, *kann, *kunþē, *kunþaz.[1]

Etymology

It is from Proto-Indo-European *ǵneh₃- (“to know”), through a PIE *ǵn̥néh₃ti;[2] Kroonen thinks the verb was created to the secondary n-present of this root seen in Sanskrit जानाति (jānáti) and Lithuanian žinóti, 3rd singular *ǵnh₃-néh₂-ti, 3rd plural *ǵnh₃-nh₂-énti.[7]

Morphology

A preterite-present verb.[4][1][3] Kroonen explains the geminate from the singular root allomorph of the n-present.[7] Lehmann reports Seebold's view that the Gothic singular 𐌺𐌰𐌽𐌽 (kann) was formed beside the plural on the pattern of 𐌳𐌿𐌲𐌰𐌽𐌽 (dugann), the geminate coming from a following laryngeal.[8] Mailhammer counts the verb in class III, with an accepted IE etymology.[9] As with the other preterite-presents, the infinitive has the weak alternant of the stem.[10] The original past participle survives as the adjective *kunþaz "known".[1]

Evidence

The verb is attested in all three branches: Gothic 𐌺𐌿𐌽𐌽𐌰𐌽 (kunnan), Old Norse kunna, Old English cunnan, Old Saxon kunnan and Old High German kunnan, with the same alternation of singular and plural stems in each.[4] EWA dates the Old High German verb from the 8th century.[11] Outside Germanic, Kroonen compares Tocharian A knā- (“to know, to understand”), Sanskrit जानाति (jānáti, “knows, recognises”), Lithuanian žinóti (“to know”), Ancient Greek γιγνώσκω (gignṓskō, “to know”), Latin nōscō and Old Church Slavonic знати (znati, “to know”).[4]

Competing analyses

Kroonen takes the preterite-present conjugation as secondary, parallel to that of *unnaną "to grant".[12] Feist explained the singular 𐌺𐌰𐌽𐌽 (kann) as formed analogically to the plural, on the pattern of 𐌱𐌰𐌽𐌳 (band), with the plural from an IE *gn-na-mé.[13] Orel relates the verb to IE *ĝenə- "to know".[5]

Meanings

  1. to know, to be familiar with, to recognise[4][2][1]
  2. to know how, to be able[4][3][2]

Old Norse also used the verb for "to grant" and "to be angry",[14] and Old Frisian for "to be skilled in, to master".[15]

Derivatives

  • *kunþaz "known", the original past participle.[7][1][16]
  • *kannijaną "to make known", the causative;[17][18] Orel's *kannjanan.[19]
  • *kōniz "able, knowledgeable, skilful", a vṛddhi gerundive.[20][21]
  • *kunnāną "to get to know, to test, to experience", with *-āną.[22]
  • *frakunnaną "to despise, to scorn", with *fra-.[23]
  • In Kroonen, *kannōn- "to get to know", an inchoative,[24] and *kunja- "omen", a ja-stem from the same root.[4]
  • From the same root, but formed differently: *knēaną "to know, to recognise".[25][26]
