>Pre-PIE had three vowels: *e, *a, and *o."Many" here to be read as "one".
>
>These vowels entered into combination with the 'laryngeal', *H, to produce *e:, *a:, and *o: in PIE.
>
>All pre-PIE short vowels became PIE *A, the Ablaut vowel/segment, which eventually had the manifestations *e, *o, or *Ø; which form *A took was a function of stress-accentual conditions.
>
>PIE retained pre-PIE *e:, *a:, and *o: unchanged.
>
>In many PIE-derived languages, the zero-grade of *e: was *e; of *a:, *a; and of *o:, o.
>Indo-Iranian changed all PIE *e, *a, and *o to <a>.Only if <a:> was derived from *eH, *oH.
>
>In open syllables, *o was further modified to <a:>.
>
>Indo-Iranian changed all PIE *e:, *a:, and *o: to <a:>.
>
>The zero-grade of Indo-Iranian <a> was <Ø> where possible; although various devices were used to ameliorate difficult combinations.

>The zero-grade of Indo-Iranian <a:> was <i>.
>Indo-Iranian <a> + <y> was <e:> (/ey/)No it wasn't. It was /ay/: OP daiva-, Avest. daeva-, Ved.
