The communicative-pragmatic effects in the generation and functioning of new phenomena in the Russian neological word formation of the latest period is discussed in the article. It informs about nonderivatives, created according to conventional and / or nonconventional models. It is shown that the specific intentions of the speaker and the addressee, their communicative needs, nontrivial topics of communication and the environment of speech, the features of the interaction of communicants, their communication strategies and tactics, etc. stand behind the formation of nonderivatives. Particular attention is paid to the following linguo-pragmatic mechanisms with the participation of nonderivatives: operations with semantic and pragmatic presuppositions, operations with inferences and implicatures of discourse, models for the implementation of conditions for the success of a speech act, the generation of indirect speech acts and speech reproduction of communicative strategies de dicto and de re use, contexts of using metalinguistic operators. The emphasis is made on the fact that the use of derivatives leads to semantic compression, the semantic capacity of the entire expression due to the actualization of various kinds of implicit information. The authors come to the conclusion that new formations in modern Russian speech testify to social attitudes, value priorities and speech-behavioral stereotypes of the speakers of the modern Russian language.
