Proto-Yenisseian: *ʔūs- (~x-)
Meaning: to hold
Ket: úś-qot (Werner 2, 366)
Yug: u:skat́
Comments: ССЕ 202. Werner 2, 366, saying that the reconstruction *ʔūs- is questionable because a morphemic alternation us / uj is observed. It is, indeed, observed, being part of the productive Ket -s- / -j- alternation in verb forms and compounds (with -j- appearing before voiced consonants) - but does in no way contradict the reconstruction of PY *ʔūs-.
