Contested; Lehmann list several possibilities. Possibly to be connected with the first element of Old Norse niðfǫlr, in which case the Old Norse word might mean "rust-yellow". Perhaps from Proto-Germanic *nidwō (“going down, sinking, downfall”), or from a compound involving the same first element as Old English neowol, or perhaps from Proto-Indo-European *ney- (“to be aroused, shine”) (whence latin Latin niteō (“to glitter, shine”)).
