Forms
knífr m (genitive knífs, plural knífar) (strong a-stem)[1] Runic knif on a find from Lund, Denmark (DR EM85;462A).[2]
Etymology
It is inherited from Proto-Germanic *knībaz (“knife”),[1][3][4] with the cognates Old Frisian knīf, Middle Low German knīf and Middle Dutch cnijf, and German dialect Kneif (“shoemaker's knife”).[3][5][6] Old English cnīf appears only in late Old English and may be from Norse.[5][7]
Forms with ⟨p⟩ stand beside it, Middle Low German knīp (“knife”) among them;[3][8][5] Orel and Ásgeir Blöndal Magnússon relate the word to the verb for “to pinch” in spite of the different consonant, from a Germanic stem meaning “to squeeze, nip off”.[3][8][5] Köbler traces it to Proto-Indo-European *gneybʰ- (“to pinch”).[4][9] Falk instead took the first sense as “curved tool”, noting that kneif is above all a fisherman's knife, and linked it with kneikja.[5]
Earliest recorded meaning
Two runic finds may be older than the manuscripts: a piece from Lund that says knífr mælti “the knife spoke”, dated to the eleventh century by Rundata with a query, and one from Germany with Pái á knif góðan “Pái owns a good knife”.[2][10] The first dated manuscript records are cnifi in AM 619 4to of 1200–1225[11] and, about 1220, a woman who bra … cnífe oc leitaþe at scera a halsinn “drew a knife and tried to cut at the throat”.[12]
Semantic evolution
The knífr was the knife or dirk worn at the belt; a knife with a belt was a usual gift, and the handles were carved from walrus ivory.[13] Deila kníf ok kjǫtstykki “to share knife and piece of meat” meant to live together as kinsmen, a phrase of the Grágás and the sagas.[14][12] Kaupa um knífa “to exchange knives” is said of a woman changing her husband.[15][14] In poetry it is a word of Atlamál, where Hǫgni's heart is cut out with a knife.[16][17]
Icelandic has hnífur, with hn- since the sixteenth century, beside knífur.[8] The mainland languages have Swedish, Danish and Norwegian kniv.[5] English knife is usually taken from Norse, though the West Germanic cognates leave room for a native word.[7][18] French canif “penknife” is also of Germanic origin, possibly through Old English.[5]
