Complex synonymic signs are formed in the system (language) as a result of the activity of psychomechanisms and represent themselves the transforms of primary syntagms and propositions. They are actualized as lingua-discursive signs in the form of synonymic structures that can be reduced, extended and quantitatively equacomponential grammaticalized (conventional in language and in discourse) and typical (conventional in discourse and non-conventional in language) and atypical (non-conventional in language and in discourse) agrammaticalized co(n)textually pertinent preferential options produced with the aim to facilitate or to complexify the interpretation of the information and the revealing of the author’s communicative intention by the recipient. The typical and atypical agrammatization is one of the characteristics of the author’s idiostyle who, in the process of the actualization of synonymic structures, demonstrates the minimal degree (typical agrammaticalized preferential options), the medium degree (atypical synonymic structures with partial agrammatization) and the maximal degree (atypical synonymic structures with complete agrammatization) of “discursive freedom” using the communicative strategies сonsisting in the elimination of structurally and / or semantically redundant elements in the intra- and / or interphrastic co(n)text or in the expressive accentuation of some referents.
