<p><tt>Is it *W that is involved in the Dhegihan positional ama'/aba'/apa' ? I.e.</tt><br>
<br>
<tt> Dh. *aWa' => OP ama', Ks aba', Os apa' ?</tt><br>
<br>
<tt>Would a single phoneme, if one could be found, be acceptable on other grounds as a reconstruction for the consonant in the above set?</tt><br>
