FUNCTIONALITY OF PARENTHETICAL MODAL WORDS IN THE SPEECH OF ADULTS AND CHILDREN

The object of the study is the function of parenthetical modal words in terms of the system of language (synchrony vs. diachrony), in textual discourse, and ontolinguistics. Parenthetical words are interpreted in connection with the concept of modus and the subjective text perspective model. A condition for the formation of parenthetical words is the appearance of an egocentric component in the semantics of the lexeme. The egocentric nature of these units is manifested in the restriction of the personal paradigm and the consolidation of particular variants of a subjective paradigm for a given lexical unit; their discursive essence is manifested in the possibility of using them as connectors and in coordination with them. Different syntactic positions words with epistemic semantics and the textual functions of parenthetical words in third-person narratives are considered. The paper is based on materials of the NCRL (artistic narrative), as well as data of speech ontogenesis obtained via longitudinal and cross-sectional methods. The materials presented include decoded and morphologically tagged (in accordance with CHILDES) audio and video recordings of early «adult — child» dialogue, as well as data on the oral and written speech of Russian teenagers, supplemented by questionnaires reflecting their attitude to the parenthetical words.
