Re: [tied] Bader's article on *-os(y)o

Concerning the development of plural *-es:

Is it possible that plural *-es descended from a plural pronoun that
came to be attached to nouns? It seems to me that (Pre-)PIE had
plurality in pronouns before it had plurality in nouns. One piece of
evidence in favor of this, I think, is that *-es attached to thematic
nouns lengthened the stem vowels, e.g. *ekWo-es > *ekWo:s 'horses.'
Thus, the use of the *-es suffix must have occurred after the
fixation of the thematic vowel quality as /o/.
