Proto-Yenisseian: *ʔǝmas (~x-)
Meaning: thorn
Ket: ʔʌmasiŋ5 'thorny', Bak. ʔʌmaś5 'thorn'
Yug: ʔʌmasiŋ5 'thorny'
Comments: ССЕ 191. Werner's (1, 406) analysis as ʌm 'thorny' + as' 'feather' is very dubious - primarily because nothing like ʌm thorny is attested (Werner adduces a form ʌ́ntaveroś 'thorny', in no way pointing to *ʌm: it obviously contains the same root as Ket. ʌ:ndɔ 'to prick', see under *ʔVq-).
