Abstract
It is proved that the imperative of modern linguistic science is a multiparadigmatic approach in the study of existing facts of language and speech, which is manifested in the priority of three basic principles: explanatoriness, anthropocentrism and functionalism. During this study we found that the complexity of approaches in research provides objectivity and completeness of knowledge about the phenomena under study and allows to solve urgent problems. In this regard, we made an attempt to show the ways of studying the problem of inner valence of morphemes in various areas of modern linguistics (on the material of newspaper discourse neologisms). Attention is paid to the solution of the problem of valence in the direction of sociolinguistics, which allows to establish the non-linguistic causes of the emergence of new words and explore through the neologisms the space of the language functioning outside its autochthonous territory. We analyze body of neolexical item in author card index records and its wordbuilding processes in the discourse activity of Russian-speaking mass media of Kazakhstan, allows us to conclude that extra-linguistic factors causing the birth of new categories include the politicization of society, the adoption of western economic system, the rapid technical development.
