Reconstruction notes

• This word has a consonant cluster *-gm- which has caused much controversy over what its Goidelic outcome should be.
  • Unlike many other obstruent + nasal clusters, -gm- does not seem to yield a long vowel via the deletion of -g- and compensatory lengthening; instead, the -g- is preserved.
  • Many scholars, across centuries, refused to accept that the preservation of the -g- in a cluster -gm- could happen, and therefore deny a connection with Ancient Greek ὄγμος (ógmos).
