In recent decades, the creation of linguistic corpora and their application in research and education have become increasingly relevant. This article examines the issues related to the representation of linguistic terms in the Uzbek National Corpus (UNC), their systematization, frequency, contextual usage, and standardization. The study employs descriptive analysis, corpus linguistic methods, comparative analysis, and a historical-typological approach to investigate how linguistic terminology is reflected in the corpus.The findings reveal that although a considerable number of linguistic terms are present in the Uzbek National Corpus, certain key terms remain insufficiently represented. Variability in terminology (e.g., parallel usage of synonymous forms) indicates the need for further standardization. Frequency analysis shows that highly frequent terms such as “word,” “sentence,” “linguistics,” “phonetics,” and “morphology” play a central role in educational and scientific discourse. The study concludes that improving the terminological database of the Uzbek National Corpus will contribute not only to linguistic research but also to lexicography, translation studies, and language teaching methodology.
