Typology and the phonetics of laryngeals

[petegray]

On this subject it's perhaps worth adding that the deh3 root shows forms in
Latin as if from a root *dew-, eg the subjunctives duim, duis etc.

Gerhard Meiser ("Historicher Laut- und Formenlehre der lateinischen Sprache"
1998 section 122.3 ) says: An original aorist lies behind "duim "duis" etc.
(from do: give) < *dow-i- with suffix -i-, derived from the aorist stem
*dow- < *dewh (parallel form to the root *do:, PIE *deh3).  The present is
found in Faliscan douiat (= det, "let him give").

Is this further evidence of the rounding of h3?
