Abstract: The article is devoted to the frequency of the use of buzzwords. The phenomenon of 'buzzword' is of great interest for many modern linguists while it still does not have a clear definition. This research presents an attempt to describe and, if possible, explain an important indicator of buzzwords which is the subjective frequency of the use of a linguistic unit as calculated on the basis of a linguistic corpus. The researcher of the article demonstrates that there is not sufficient estimation of the frequency of use of buzzwords on the basis of corpus texts and offers an experimental linguistic method to determine the subjective frequency. The main research methods used by the author of the article is description, comparison and experiment which have allowed to define different advantages and disadvantages of objective and subjective frequency of the use of buzzwords. The novelty of the research is caused by the fact that for the first time in the academic literature the researcher have analyzed the main gaps and problems related to estimations of buzzwords carried out on the basis of corpus texts (difficulty of presenting results, challenges of analyzing conversational and network materials, late update of data and materials, unprecise distinction of word semantics); the researcher has also demonstrated opportunties of the method of successive intervals and has proved the importance of the aforesaid method by describing the Word of the Year project.
