Re: [tied] *h3 (This odd feeling of deja-vu)

I guess we can always sugggest -oh1- or -oh2- instead of -eh3-! But that
leaves me with two questions:
(a) What about h2o? There is an arguable case that the reflex of h2o is
/a/ in Greek and Latin, not /o/. See Sihler p45.
(b) As I said in a previous post, isn't it better to keep a regular -e-
grade in some of these verbs, expecially in forms such as the reduplicated
presents? The pattern that is beginning to emerge of -e- in some forms
and -o- in others is broken if we have o-grade in all the places that
require h3.

In addition, are there traceable characteristics of h3 other than being a
laryngeal? Two have been suggested:
(i) voicing - which is based on slight evidence.
(ii) rounding - are there any instances where a labial environment would
be helpful, which we couldn't explain from an o-vowel?
