The proposal consists in that the stem or thematic vowel segment gives rise to variations or asymmetries across tenses in certain languages, which makes the processing or derivation of verbal forms more complex or longer: such languages are V-to-T languages.
The idea that I would like to propose is that the morphological richness that is at the base of V-to-T is to be identified with the so-called stem or thematic vowel, in the sense that this segment can provoke systematic variations or asymmetries across the different tenses in the languages in question, in the way to be justified later on.
Elamite has a regular pattern of aphesis where the initial vowel of #VC roots is lost and where the thematic vowel is mandatory for verbs.
In essence, I defend in this paper that V-to-T movement is a core syntax process and that the trigger of V-to-T lies in a specific type of morphological segment that is known in the traditional philological literature as stem vowel or thematic vowel, and that is the segment mediating in the verbal forms of some languages between the root on the one hand, and [tau]-features and [phi]-features on the other.
Alternatively, verb stem can be defined as the morphological segment that results from the union of the so-called verbal root on the one hand and the stem or thematic vowel on the other.
the appearance of a thematic vowel -i- (in competition with the usual -a-), and the presence of the consonant -h- instead of -ss- (from -sy-).
It should also be noted that Pisani's proposal cannot explain the appearance of the thematic vowel -i-.
Blau endorses to a certain degree Barth's theory that there is a connection between the thematic vowel of the prefix conjugation and the thematic vowel of nouns, e.
Over a century ago Jakob Barth suggested, (1) in what has come to be known as Barth's Law, that the quality of the vowel following the consonantal pronominal prefix in the G-stem depends on the thematic vowel of the verbal base, i.
But beyond the fact that this analogy is somewhat artificial, there are no n-stem proper name pairs attested in the languages that support this analysis, nor do proper names with n-stem second members seem to have regularly replaced this suffix with the thematic vowel.
The analysis of both authors obscures an original thematic vowel -a- by treating it as part of the suffix (so also with the -i- theme in the case of +t-, +n-); they also conveniently (but incorrectly) overlook forms with an -o- thematic vowel.
the imperative and those forms with a prefixed subject-marker); and (2) the systematic appearance of the thematic vowel i (or a, in the environment of a post-velar radical or [r.
