Re: Dating *e > *i in Germanic

Incidentally, what is considered the main evidence for early Finnic avoidance of *-o- in non-initial syllables?

Most of the IE branches that have uncontroversially contributed words to Uralic are also branches in which short *o generally shifted to *a -- Slavic is the only exception that comes to mind right now.

Avoidance of -o- (and not -a-) in second syllables (irrespective of the first syllable's content) seems a somewhat abstract rule to have been sustained over a time period as long as Uralic > Finnic, but perhaps that's just my inexperience speaking.
