Two options: * either from Proto-Finno-Ugric *ćolme (“knot, bundel; to bind”), cf. Hungarian csomó (“knot”), for the semantic shift cf. also German Knoten (“knot”) vs. Knochen (“bone”) (with a noun-forming suffix -t added in Hungarian, cf. evet, nyest, menyét, but the last three words might have a diminutive -t instead), * or from Proto-Finno-Ugric *ćutte (“ankle bone”), for the semantic shift cf. Finnish kontti (“shinbone”) vs. Estonian kont (“bone”) and German Knöchel (“ankle”) vs. Knochen (“bone”) (with an inorganic -n inserted in Hungarian, cf. csüng, ránt). This explanation is less convincing as the only supposed cognate is in Sami, a language distantly related to Hungarian.
