The "Theory of Specialization in Language with a Focus on the Verb," with reference to the "example of the Greek language," is the result of a long personal contemplation on the essence of the verb's function in the sentence.

Assuming that the verb in human communication constitutes an expression of the Heraclitean "becoming," that is, the constant alternation of daily actions and states in our lives, we support that the full verb (do-verbs) operates as the center of the sentence ("logical energetic triad"), with all the surrounding elements, syntactically and semantically, composing graduated degrees of specialization of it and among themselves.

Accordingly, we hold that in copular syntax, the other pillar is revealed, the "being" of language, again with the verb (be-verbs) at the center and with a specializing function of the remaining terms ("specialized identity triad").

The proposed "Theory of Specialization" naturally leads to revisions and even overturnings of existing forms of analysis, such as, for example, the "tree" depiction of the hierarchical structure of the sentence, in which the directly dependent element is the verb and not the subject, since the subject depends on the verb ("subject of the verb").

Ultimately, we argue that the proposed function of the verb has a "universal" character, with various typological parameters.
