In this article, the words used in literary works are shown to have certain differences from both the lexicon of live speech and the vocabulary of popular science texts. Such differences, especially variations in speech styles, are thoroughly explored in linguistics. The use of words in literary works has also been studied according to their frequency of occurrence. According to the calculations of S. Rizaev and N. Buronov in their “Frequency Dictionary of the Language of Abdulla Qahhor’s Novella “Sinchalak”, a total of 37,482 words were used in this work, representing 10,590 dictionary units. In Uzbek language classes, the accuracy, completeness, and depth of reading literary texts, understanding their content, and artistic perception largely depend on how well students have mastered the lexical and grammatical materials within them. “Building vocabulary”, says L.A. Sheyman, “is the primary way to overcome the language “barrier” that students face when studying examples of Russian literature in the original”1. This approach becomes even more crucial when studying examples of Uzbek literature, considering that the Uzbek speech of Russian-speaking students is not at the required level.
