If <suwais> is related to <avis> (I have some new ideas concerning its
etymology, but I'm still working on it and wouldn't like to divulge the
details prematurely), the loss of *h2 is of course regular between an
s-mobile and a consonant. Hitt. sakuwa is, in my opinion, best explained
as a a thematic deverbal noun from *sekW- 'follow, join, accompany'
(with secondary meanings like 'see'). Any original connection with
*h3okW- is IMO doubtful despite the similarity of both roots and their
semantic convergence.
