>On the ancient allophony of *k and *q:So you're saying that *q arose from **k in the neighbourhood of **a.

>Glad you asked. PIE *o was once *a, a central unrounded low vowel. The
>*a that we find in PIE derives from earlier *A as in Canadian "cat" [kAt].
>It

>The connection between Mid IE *a (>*o) and *q is that both have
