Abstract
The article is devoted to the study of the lexicographic experience of describing the youth lexicon and the theoretical foundations of its complex multidimensional representation in the dictionary. At the present stage of development of the Russian language, its lexical system is being rapidly updated, which is due to various extralinguistic factors. One of the signs of the times is the activation of occasional word formation. The main reason for the appearance of occasionalism is the need for a special means of expression that arises in the process of communication. The authors of this article have studied occasional words, which are the result oflinguo-creative activity of students (aged 17 to 21). The chosen approach provides an opportunity in the process of research to find out which areas of reality, already indicated by the vocabulary of the literary language, are covered with new formations for the second time. Such facts testify to the undeniable importance of these areas in the life of native speakers of this age group. The term «occasional word» in the proposed work is used to refer to «all speech innovations, systemic and asystemic; speech neoplasms created with deviations from the modern word-formation system of the language; system formations that are the implementation of a productive word-formation model in a speech act. The main method for describing the identified occasional neoplasms was ideographic classification, i.e. systematization of words on logical and conceptual grounds: reality is divided logically, and lexical units are correlated with one or another isolated sphere. Within the allocated spheres, separate areas are distinguished, each of which is divided into smaller groups.
