between the parties. p align="justify"> Historically the theory of actual division of the sentence is connected with the logical analysis of the proposition. The principal parts of the proposition, as is known, are the logical subject and the logical predicate. These, like the theme and the rheme, may or may not coincide, respectively, with the subject and the predicate of the sentence. The logical categories of subject and predicate are prototypes of the linguistic categories of theme and rheme. However, if logic analyses its categories of subject and predicate as the meaningful components of certain forms of thinking, linguistics analyses the categories of theme and rheme as the corresponding means of expression used by the speaker for the sake of rendering the informative content of his communications .
The actual division of the sentence finds its full expression only in a concrete context of speech, therefore it is sometimes referred to as the "contextual" division of the sentence. This can be illustrated by the following example: Mary is fond of poetry. p align="justify"> In the cited sentence, if we approach it as a stylistically neutral construction devoid of any specific connotations, the theme is expressed by the subject, and the rheme, by the predicate. This kind of actual division is "direct". On the other hand, a certain context may be built around the given sentence in the conditions of which the order of actual division will be changed into the reverse: the subject will turn into the exposer of the rheme, while the predicate, accordingly, into the exposer of the theme. Cf.: "Isn't it surprising that Tim is so fond of poetry?" - "But you are wrong. Mary is fond of poetry, not Tim. "p align="justify"> The actual division in which the rheme is expressed by the subject is to be referred to as "inverted".
The close connection of the actual division of the sentence with the context in the conditions of which it is possible to divide the informative parts of the communication into those "already known" by the listener and those " ; not yet known "by him, gave cause to the recognised founder of the linguistic theory of actual division J. Mathesius to consider this kind of sentence division as a purely semantic factor sharply opposed to the "formally grammatical" or "purely syntactic" division of the sentence (in our terminology called its "nominative" division). p align="justify"> One will agree that the actual division of the sentence will really lose all connection with syntax if its components are to be identified solely on the principle of their being "known" or "unknown" to the listener. However, we must bear in mind that the informative value of developing speech consists not only in introducing new words that denote things and phenomena not mentioned before; the informative value of communications lies also in their disclosing various new relations between the elements of reflected events, though the elements themselves may be quite familiar to the listener. The expression of a certain aspect of these relations, namely, the correlation of the said elements from the point of view of their immediate significance in a given utterance produced as a predicative item of a continual speech, does enter the structural plane of language. This expression becomes part and parcel of the structural system of language by the mere fact that the correlative informative significance of utterance components are rendered by quite definite, generalised and standardised lingual constructions. The functional purpose of such constructions is to reveal the meaningful centre of the utterance (ie its rheme) in distinction to the starting point of its content (ie its theme). p align="justify"> These constructions do not present any "absolutely formal", "purely differential" objects of language which are filled with semantic content only in the act of speech communication. On the contrary, they are bilateral signemic units in exactly the same sense as other meaningful constructions of language, ie they are distinguished both by their material form and their semantics. It follows from this that the constructional, or immediately systemic side of the phenomenon which is called the "actual division of the sentence" belongs to no other sphere of language than syntax. And the crucial syntactic destination of the whole aspect of the actual division is its rheme-identifying function, since an utterance is produced just for the sake of conveying the meaningful content expressed by its central informative part, ie by the rheme.
Among the formal means of expressing the distinction between the theme and the rheme investigators name such structural elements of language as word-order patterns, intonation contours, constructions with introducers, syntactic patterns of contrastive complexes, constructions with articles and other dete...
