Leksika srpskog jezika u XXI veku

This work is dedicated to new words in the Serbian language that were created during the XXI century. In the first part of the paper, theoretical considerations about neologism are presented and the differences between neologisms in the past and today are presented. It is concluded that social changes in the 21st century also led to a change in the nature of new words. In the past, new words were mainly used to name new objects and phenomena, and today new words are most often associated with ideological phenomena. In the second part of the paper, as representative examples of the lexicon created in the 21st century in the Serbian language, we treated the neoderivatives created by adding today's very productive prefixes anti-, de(z)-, pseudo-, para- and quasi-. The first two components as well as the lexemes that are built using them belong to one semantic group, and the remaining three belong to another, but they are connected by high productivity in the modern Serbian language, as well as the meaning of deviation from the expected, demolition or deformation, i. e. twisting established values or dominant points of view on phenomena and processes.
