Abstract: The subject of this research is the abstract model of functionality of cause-and-effect relations, which can be depicted as a construct x leads to y, where x is producing cause, and y – the effect. Leaning on semantics of the text, this model can be presented as P, cause that leads to P effect, where P is any semantic predicate, being on the place of either causing element or the effect element. The object of this research is the texts with cause-and-effect semantics. The goal consists in examination of the structure of cause-and-effect relations from the perspective of the logic of language and the semantic of text. The main conclusion is the depiction of cause-and-effect relations through the simplest binary model, in which the chain is created between to situations of propositions. Elements of the model are interconnected – one situation exists because of the other. Such relationship can be determined on the in-depth level – a semantic element equal for both situations, as well as on the meaningful level – connection between the elements of the situation. The study applies the methods of component analysis, propositional analysis, and contextual analysis. Relevance of the article is substantiated by referring to such modern linguistic trends as the logic of language, semantic syntax, and syntax of the text.
