Re: [tied] PIE grammar made simple (1)

I don't wish to dispute your outline of PIE aspect, Piotr, but I do have a
question.

Outside Greek, what evidence is there for the aspect system you describe?

The formations are clear from a number of IE languages, but their usage
varies enormously.

Latin shows no difference in usage or aspect between PIE aorist and perfect
tense forms.

Sanskrit shows no clear distinction at all in usage between the PIE
imperfect, aorist and perfect forms (although there is room for debate here)

Hittite does not show the pattern.
Slavic has remodelled its verbal system and aspect is a new formation.
Germanic has a newly built system, based on PIE patterns.
Celtic ?

So I am left wondering how far we are reading a purely Greek model back into
PIE, and how justified we are in doing so.
