compensating for the immobility of stress in this type of aorist. At
any rate, I wouldn't accept any solution that doesn't explain the
athematic "Narten presents" at the same time (the *té:k^s-ti : *ték^s-
enti type), and if it explained vowel alternations in Hittite
conjugations as well I'd know it to be _the_ solution.

At first glance, we again have a closed (stressed) syllable in
*té:k^s-ti and open in *ték^s-enti (if *k^s- is not prohibited in
anlaut by PIE phonotactics, at least I suppose the *k^ 's sonority
was less than that of *s). Of course one can point to lots of
instances with unlenghthened stressed closed syllable, but probably
this is at least one of the factors?
