If we also have in Estonian the following...
mina tulin
sina tulid
tema tuli
... with an _endingless_ 3ps then it would seem that we can deduce
what happened to the 3ps. Having become endingless, it shows the bare
participle marker *-pa. So of course it "LOOKS" like a participle simply
became a 3ps verb but unless we _actually_ have such a case, please
spare us the deception. As far as I can see, verbs can be conjugated
with personal endings with the so-called "participle" endings which
smell to me like the same sorts of modal "extensions" that IE has
between the verb stem and personal endings. This isn't a clear case
of participle-turned-verb at all. It's a verb-turned-verb. Whoopee!
