Yes, I saw you attributing that to me in a recent posting.
But I am almost sure I got that idea from you.

OK, I like that. That would explain Grk. kúkla, Lith.
s^im~tai, and for that matter also Slavic però, pèra. But
what I find more difficult is that it should also have
worked in the reverse (neûron, neurá).

In any case, if PIE already had *pteróm, pl. *ptérah2,
that's an important precedent for Balto-Slavic to introduce
mobility in other thematic forms.

Examples?
