köken: From Proto-Finnic *nocko (compare Estonian nõtk), from Proto-Finno-Permic *ńočka.
köken: From Proto-Albanian *grykā-, from Pre-Proto-Albanian *grūkā-, from Proto-Indo-European *gruHkeh₂, from older *gruHkó- (“turning, curving”). Orel claims from Proto-Albanian *grīwīkā, from Proto-Indo-European *gʷriHwéh₂, from *gʷerh₃- (“to swallow”). While *-iwi- to -y- is possible, there is no explanation for the inherited -kë suffix.
