Using the thesis of K. Buller about the expedience to distinguish a separate language function and a separate language sphere – a sphere of appeal, which is opposed to representation and expression, the author of the dissertation grounds the existence of a specific functional sphere of appeal in the language, which fulfils the corresponding function. The author of the dissertation conceives the sphere of appeal as a semantic-grammatical complex, which consists of two meaningful parts – predicate and subject ones. The analysis of the representation of appeal in different types of expressions in the Ukrainian language (from the point of view of communicative objectives) allowed to construct the typology of these manifestations and to outline the circle of the main representatives of the appeal.
The predicate part of the content of appeal is realized with the help of the synthetic forms of the indicative mood of the verb (their functional equivalents). The subject part of the content of appeal is represented by the forms of the vocative case of nouns (their functional equivalents). The analysis of the peculiarities of the expression of the semantics of appeal allowed to constitute the identity of its material expression with the help of the grammatical forms of verbs and nouns which is caused by the commonness of the functions performed. The author proves the existence of the forms of the vocative case in the paradigm of adjectives, pronoun nouns and pronoun adjectives of the second person as well as of nouns.
The analysis of the semantic-syntactic structure of the complexes of appeal proves the existence of two syntaxemes of appeal in the language system – the imperative one (expresses the predicative part of the content) and the vocative one (expresses the subject part of the content). The common semantic-syntactic feature of the above mentioned syntaxemes is the one of the second person.
The elements of appeal function on the formal-syntactic level of the sentence being a part of the two-member sentence as specific one-member sentences (vocative), occupying at the moment the formal-syntactic positions: of the predicate, principal member of mononuclear definite-personal sentence, inserted element with a predicate meaning; subject in the sentence with the predicate expressed by the verb form of the second person (the imperative, and also the indicative and the subjunctive mood); principle part of the vocative sentence; inserted nuclear components in the constructions of representation; principle parts of the conjunctive vocative sentence; mediated secondary identifying parts of sentence while the vocative form (its functional equivalent) is allocated in the postposition concerning the pronoun word in the second person in the direct case; mediated secondary appeal identifying parts of sentence while the vocative form (its functional equivalent) is allocated in the postposition concerning the pronoun word in the second person in the oblique case. The paradigm of sentences of appeal consists of 18 types of two-member sentences and 3 types of one-member ones.
Speaker's choice of the means of expression of appeal is stipulated by the system of pragmatic factors. The peculiar feature of the Ukrainian language is functioning of the system of the means of appeal; as described in the dissertation regularities of the lexical-semantic filling of the grammemes - representatives of appeal.
The means of appeal in the Ukrainian language perform important stylistic tasks. Appeal is represented in colloquial, belles-lettres and publicist styles in the most various ways, the elements of appeal occur in official and scientific styles. The use of the means of appeal is very original in epistolary and sacral texts, and very often the peculiarities of these texts influence the choice of the expressive means in the texts of other styles.
The choice of the suitable means of appeal and the specific character of their representation in language constructions is a bright manifestation of national peculiarities of one nation or another, which form and develop during its long-term development by means of creation of their own means and also as a result of the influences of other national cultural-language traditions.
