Objects of relational grammar (functional aspect)

The article develops the ideas of M. I. Cheremisina, which the author views as a program of relevant and promising studies in the realm of relative grammatics. The author relies on these to prove the necessity of selection of a separate functional-relational level of linguistic analysis - study and classification of language units according to their relational functions. The continuity of functioning and development of language permits to view relativization of lexis primarily as a process where the belonging of language units to various parts of speech is irrelevant: a content word is able to perform the constructive function, not crossing the borders of its part of speech, which the author demonstrates on example of parametric words, names of body parts, etc. drawn into the class of prepositions. Within this approach, relational words, traditionally viewed as auxiliary parts of speech, are morphosyntactic in their nature, which permits to discover a group of language units not described in existing grammatical resources and/or not included in the relational class. The article presents the results of description of methods (experimental method and theoretical modeling) of detection of conjunctions on the basis of prepositions. The article lists the functions of relational words, draws the possible limits of the relational class and lists the units gravitating towards this class.
