Екзистенциални изречения с глаголите esse и habere в българския език в съпоставка с другите славянски езици

The article discusses some peculiarities of the verbal and the nominal component in existential sentences with съм and има in Bulgarian with the rest of the Slavic languages in the background. In Bulgarian there is a formal contrast between sentences of common and concrete existence. The peculiarities of the investigated existential sentences are influenced by nominal analytism, the outward expression of definiteness/indefiniteness in nouns, in doubling of the object, as well as the widest among the Slavic languages sphere of use of има as a verb of existence.
