Linguistic sign; Grammatical sign; Verbal tenses

This article hopes to achieve a double purpose. We distinguish coded form and coded content of the sign (langue, I) and occurring (realized, materialized expression related with occurring (contextual, uttered, communicated) content (II, parole). The relation form ? content (I or II) is asymmetrical (homonymy ­ homomorphism: homography, homophony; synonymy). The meaning of a homonymic / synonymic sign is given by the type of distribution; a grammatical category can appear as a cryptocategorie (Šabršula 1963), the meaning of the sign is determined by the synergetic (synergistic) character of a crypto/category or word! Likewise, the meaning of morphologic or a premorphologic category depends on the type of distribution.
