Abstract

In Russian language, the difference between sentences as a syntactic unit depends on the combination of words, predicate or the message of it. The subject and predicate as the main structure of the sentence carries this message, which should be in the appearance of at least one of the sentences. The syntactic relation between subject and predicate can be determined by the type of subject in the sentence. If there is a grammatical subject in the sentence, the coordination and accordance relation will be in the sentence. in this relation, the predicate is a conclusion of subject and follows it in the gender, count, and person. But if the subject is not grammatical, there will be no relation between the subject and predicate. A case in which the subject is logic in a sentence, its relation with the predicate will be syntactical conduction. In this case, the predicate determines the grammatical type of subject and this time the subject follows the predicate.
