What is the subject
The subject - it is one of the two main parts of the sentence. The word or words in this role, indicate the object to which the reported. The subject can be isolated in a simple sentence, in the main and accessory parts of the complex and sometimes - in the predicative structures, which are formed by impersonal forms of the verb.
Instruction that is subject to
The subject can be expressed in different parts of speech. This is usually a noun in the nominative case or its equivalents - personal, relative, indefinite, interrogative pronouns or negative. Also subject may be a numeral, a proper name, and even a verb (infinitive form).
The composition of this part of the sentence in the Russian language is not always limited to a single word. Sometimes the subject is represented syntactically or lexically indivisible phrase. It may be popular expressions, compound names of institutions and geographical indications, set phrases. Nouns that denote quantity, can act as a subject, if combined with a noun in the genitive case (many people). Numerals "many," "few," "many," and must be combined with a noun in the genitive case, and indefinite pronouns - with the adjective.
May be subject to design, consisting of a noun or a personal pronoun in the nominative case, the preposition "with" and a noun in the instrumental case. Another similar scheme - adjective, pronoun or numeral in the nominative case, together with the preposition "from" and the noun or pronoun in the genitive case.
The unequivocal answer to the question of whether or not subject to the hierarchical apex of the proposals does not exist. Grammarians, for example, claimed subject apex, because it, unlike the predicate denotes independent entity. Other researchers have proposed to define the dominant proposals, removing grammatically dependent parts. As a result of this analysis offers the core becomes the predicate and the subject falls into the same category as other registered members of the proposals, which are dependent on the predicate (actants).
However, the function to be set it apart from the rest of nominal sentence. Typical features of the subject are its autonomous or unlabelled form of the name (in the Indo-European languages is a nominative case), certain syntactic position, consistency with the predicate, the autonomy of reference correlation with reflexive pronouns, the omission at the next predicates, the presumption of the existence of the designated object, the ability to be a subject of verbal participle turnover (in Russian).
