Reconstruction:Proto-Germanic/meluks

Etymology
From. Cognate with 🇨🇬.

The presence of in the second syllable is aberrant, as it was not present in the PIE root or even in the related Germanic verb. However, the evidence of all descendants speaks unambiguously in favour of its presence. Aside from being directly attested in most of them, it is also implied by Old Norse u-mutation in case forms where it would not be expected, in the raising of e to i before u in the non-Ingvaeonic West Germanic languages, and in the High German shift /k/ → /x/.

Possible theories of origin of the disputed :
 * According to Kümmel, the vowel *u is an anaptyctic vowel, inserted after the resonant to ease the complicated cluster of three consonants *VRCs#.
 * According to Szemerenyi (1992: 1125) it is the result of contamination of the full- and zero-grade in an ablauting paradigm, genitive , but this leaves the Schwebeablaut unexplained.
 * According to Bammesberger (1990: 196f) this */u/ represents a schwa that arose between the */l/ and the */k/ in the nominative . However, this solution fails to explain why the same did not happen in e.g.
 * According to Kroonen, originates from the strong verb, whence this archaic root noun likely derives. This does not answer the ultimate origin of the u however.
