Deliberative joint о том, что and model of complex sentences with object clauses

On the basis of syntactic joint differentiation in complex sentences with object clauses, sentences with proper object clauses, object-topical clauses and interrogative object clauses may be differentiated. The joint о том, что, which is included in the subordinate clause, serves as a marker of sentences with object-topical clauses. The pronoun то only formally belongs to the superordinate clause and is actually used to express the deliberative relations between clauses, which denote the theme of the statement in the most general way. The article describes the possible variations of this joint and discusses the variations of models of various object clause types.
