If we were to lay out some of the reconstructions, for our example we'll use some enclitic pronouns from the Northwestern IndoEuropean branch for Illustration, it might look like this:

*At least in some cases, ū is
actually reconstructed as ō in Northwest IndoEuropean, but this
distinction isn't such that it would have an impact upon the
correlations noted above. (And in the case of my own speculative
chart specifically, nearly all of them are reconstructible as /ō/)
*plural forms jos reconstructible as
jūs/jōs; And may well derive from an adjectival form of this
pronoun. Adjectival forms has -w- between the root and the vowel
ending.
Any thoughts? Opposing? In favor? Uncertain?
