Since the notions of semantic and syntactic coreference, in the conceptual,
terminological and theoretical sense, have long been known to the linguistic
public, we consider it appropriate and worthwhile to point out the ways in
which this type of connection between the grammatical units in the sentence
is materialized. We especially wanted to draw attention to the inherent
mechanisms of language which directly signal that the two forms, not
necessarily different, are connected with the same meaning, and related to
the same semantic role, for which it is directly responsible - the same
propositional function they have. Although it may seem that the difference
between semantic and syntactic coreference is not so significant, it has been
revealed that in the latter case, the syntactic relations are the main
language means of expressing propositional functions and corresponding
semantic roles. Therefore, the purpose of this study is to highlight the
syntagmatic mechanisms of language, with the help of which the structural,
informative and informative hierarchy of the sentence members is carried out.
The purpose of such hierarchization is not so much to streamline or rethink
the structure of the sentence, but rather to ensure the integration of
complex content on the one hand, and settle the situational significance of
individual participants on the other hand.
