I know that the IE active participle of present and aorist is in -nt, while the perfect has -wos/-us.
Likewise, the passive participle of present and aorist is in -mH1no-
But, I wonder, did the IE perfect medio-passive participle use the same ending ? I know Old Greek did (ex: lelumenos = "having been undone"), but do you know examples from other IE languages ?
In my opinion, the prefix -to/-no was used in PIE not for a passive participle, but for a verbal adjective, as in Old Greek.
Ex: *bheid = "to split; *bhidstos = "fissile"
"weid" = "to know, learn"; *widstos = "knowledgeable"
What is your opinion about ?
Thanks.
