Uncertain.[1] Per De Vaan, potentially a loanword; it is possibly related to nassa (fish-trap made of wickerwork) and necto (I bind).[1]

One theory derives it from Proto-Indo-European *gned-, *gnod- (to bind) and makes it cognate to Proto-Germanic *knuttô (knot) (whence Modern English knot).

Another theory derives it from Proto-Indo-European *ned- (to turn, twist, knot), whence English net and possibly nettle, Avestan 𐬥𐬀𐬯𐬐𐬀-(naska-, bundle), Old Irish nascim (to bind).
