PH diphthongs
From User talk:Rua
Thanks for the fix on *yéwgos. I was unclear about whether *eu was a diphthong in PH because WT:AGRK-PRO does not list them. Should they be there?
I have no idea. This seems like a question for Sihler, but I'm not near my Sihler at the moment. We currently list *āi, *ēi, *ōi?
I wonder what PIE sources there are for these. As far as I know, Osthoff's law applied to Greek too.
