Definition of Thematic Vocal

Verbal conjugations depend on the role of the vowels and in this sense we talk about the thematic vowels. The vowel a designates the verbs of the first conjugation (those that end up in "ar", like dancing or thinking ), the "e" to those of the second (how to have or return) and the "" to those of the third ( how to go or leave). In other words, the conjugation to which the verb belongs determines the thematic vowel. Therefore, the thematic vowel is a phonological feature that allows knowing each verbal formal .

The thematic vowels act as a morpheme, specifically as a flexible morpheme when it comes to non-derived verbs (for example, love or sing) and as a flexive and derivative morpheme in derived or parasynthetic verbs (for example, digging or freaking out).

Illustrative examples

If we take as a reference the verbal form "possess", we find the following structure: the lexeme pose, plus a thematic vowel (the letter e) and a disinfection, the n. In this way, it is a verbal form in the third person of the plural (they or they possess) and the present indicative of the verb possess.

In the compound verb form "they would have followed", it is the third person of the plural of the past tense pluscuamperfect of the indicative, formed by the auxiliary verb having the participle of the verb follow. If we analyze the "followed" participle, we find the following structure: the lexeme follows, more "i" as thematic vowel and "gone" as the termination of the participle that acts as a flexible morpheme.

The verb and its different morphemes

Verbs are words that inform about actions, events or states that affect a person, in a given time and in a way or way. This is the grammar information provided by any verbal form. If we take as a reference the verbal form "we sang", its structure is the following: "cant" as root, á as thematic vowel, "bá" as morpheme of time, mode and aspect and finally "mos" as morpheme of number and person.

Thematic vowels in a verbal form serve as a connector between the root of a verb and its endings

In a strict sense, these vowels do not have a meaning, but they announce what the subject is (what conjugation it is) and for this reason they are called thematic vowels.

Remember that in the verbs of the first conjugation the thematic vowel is always the letter "a", in the verbs of the second the thematic vowel is the "e" and in those of the third conjugation it is the "i". This is the general rule , but logically there are exceptions to this rule (for example, in the present subjunctive of the verb sing, sing, the "a" does not appear).
