Comments: ССЕ 231. Probably the same root as in PY *sVs- 'sit' (q.v.). The status of the elements *h- and *s- is not quite clear: the former may be a preverb, the latter - either also a preverb or an archaic reduplication. It is also possible that *sVs- is a form similar to *ta-s- 'stand up' (q.v.), i.e. an original compound *sV+(hV)s- "be seated". Werner 2, 359 *ǝsǝ(ŋ) / *usǝ(ŋ).
