kniv (Danish)

Where does "kniv" come from?

The Danish noun 'kniv', meaning 'knife', descends directly from the Old Norse 'knífr'[1]. This term can be traced back to the Proto-Germanic nominal form '*knībaz'[1][2], which may derive from an unattested verb '*knībaną' connected to '*knippōną', meaning 'to pinch'[3]. Ultimately, linguists trace this lineage back to the Proto-Indo-European root reconstructed as '*gneybʰ-'[1][3].
