Oppositional representation of derivational relations: a metalanguage potential

The theoretical problem of language meta-description is considered with the support of oppositionality concept - an important feature of language system-forming relations. Oppositionality is a key characteristic of wide range of language relations, including derivational ones, which determine the identity of language dynamics. Opposition character of derivational relations is conditioned by their motivation and productivity. The importance of oppositionality in derivational processes allows the author of the article to qualify it as essential and promising basis for complex metalanguage descriptions. Particular attention is paid to the representation of language system modification capabilities in the morphological aspect, since this aspect of derivation problem domain is characterized by a significant potential of metalanguage representation. Verification and correct systematization of derivation term system has a priority in the modeling of referential language relations. The author has established that on the basis of consistent representation of basic derivational relations - in particular on the level of derivatemes, grammemes and flexionemes - a consistent development of the complex hierarchical meta-model of derivation is possible. It is shown that computer-mediated discourse provides a special urgency for such simulation as the actively developing communication phenomenon, which creates meanwhile a new quality of metalanguage practice. The base of modern speech practice - the statistical model of communication - determines the special relevance of formal criteria and parameters for the meta-description of single semantic continuum of language.
