And it should be remembered that in most of the early thematic presents
the thematic vowel was _accented_. This is in particular true of the
ordinary *-jé- and *-sk^é- presents, while in ordinary
iteratives/causatives we have *-éje-. Originally, the thematic vowel in
verbs might have carried obligatory accent, later retracted if there was
a full vowel to the left of it.
