Artificial intelligence (AI) has emerged as a transformative force in higher education, reshaping the ways in which students acquire knowledge and develop language skills. Among recent AI-driven innovations, ChatGPT has attracted considerable attention for its ability to facilitate interactive, personalized, and context-sensitive language learning. Vocabulary knowledge, as a fundamental component of lexical competence, plays a central role in learners' communicative ability, reading comprehension, writing proficiency, and overall language development. Despite growing interest in AI-assisted language learning, empirical research examining the contribution of ChatGPT to vocabulary development remains limited, particularly within the context of higher education in developing countries. The present study investigates the potential of ChatGPT as an instructional tool for enhancing English lexical competence among university students. Specifically, the study explores how AI-assisted vocabulary learning supports vocabulary acquisition, contextual word usage, collocation development, lexical retention, and learner autonomy. Employing a quasi-experimental mixed-methods design, the research proposes comparing students who receive ChatGPT-supported vocabulary instruction with those who follow conventional vocabulary learning approaches. Data collection includes vocabulary achievement tests, learner perception questionnaires, classroom observations, and semi-structured interviews. Quantitative data are analyzed using descriptive and inferential statistics, while qualitative findings provide deeper insights into students' experiences and attitudes toward AI-assisted learning. The study is expected to contribute to the growing body of literature on artificial intelligence in language education by providing evidence of ChatGPT's pedagogical value in vocabulary instruction. Furthermore, the findings may assist educators, curriculum designers, and higher education institutions in integrating generative AI technologies into English language teaching in an effective, ethical, and learner-centered manner.

Critical thinking has become an essential component of modern education, particularly in the field of language learning, where learners are expected not only to acquire linguistic knowledge but also to develop analytical and problem-solving abilities. This study investigates the role of critical thinking activities in enhancing language learning processes and improving learners’ communicative competence. Critical thinking activities encourage students to analyse information, evaluate arguments, solve problems, and express independent opinions, thereby promoting deeper engagement with language use in academic and real-life contexts. The research explores how activities such as debates, discussions, problem-solving tasks, reflective writing, case studies, and collaborative projects contribute to language development. These activities support the improvement of speaking, writing, reading, and listening skills while simultaneously fostering learner autonomy, creativity, and confidence. Furthermore, the study examines the relationship between critical thinking and communicative competence, emphasizing that learners who actively engage in analytical tasks tend to demonstrate higher levels of language proficiency and interactional effectiveness.

This scientific article studies the lexical transformation of proverbs in the work "Kutadgu Bilig" in Turkish. The process of lexical transformation in the work helps to understand the process of language development. Studying this process helps linguists to determine the historical development of the language, the changes in lexical units, and cultural influences. Lexical transformations enrich the language and expand its functional capabilities.

This paper explores the agricultural terminology of the Hindi language, focusing on its origin, linguistic features, and comparison with Uzbek equivalents. The study reveals that Hindi agricultural terms have deep historical roots, derived from Sanskrit, Persian, and English, and are constantly evolving under the influence of modern technology. The analysis highlights their semantic clarity, cultural relevance, and significance for comparative linguistic research. Introduction. Language reflects every aspect of human activity, including economic and agricultural life. Agriculture plays a vital role in India’s economy, with the majority of the population engaged in farming. As a result, Hindi has developed a rich and diverse system of agricultural terminology. This thesis aims to analyze the structure, meaning, and development of Hindi agricultural terms and to compare them with similar terms in the Uzbek language.

Motivation plays a crucial role in determining learners’ success in acquiring a foreign language. This study investigates the relationship between students’ motivation and their English language achievement among university students in Uzbekistan. A quantitative correlational design was employed using a motivation questionnaire and students’ academic results. The findings revealed a significant positive correlation between motivation and English achievement, indicating that students with higher motivation levels performed better in their English courses. The study also found that intrinsic motivation had a stronger influence on achievement compared to extrinsic motivation. The results highlight the importance of motivational strategies in English language teaching and suggest practical implications for educators.

Language is one of the most important foundations of human culture. It is not only a means of communication, but also an integral part of thinking, culture, society and history. Linguistics, on the other hand, is the science that studies this complex system and includes various approaches, theories and techniques. At the same time, there are many problems in linguistics that still require scientific research and analysis.anguage is one of the most important foundations of human culture. It is not only a means of communication.

The teaching of specialized subjects within the training of future foreign language teachers is pivotal for developing educators who are proficient in the language and equipped with tailored pedagogical skills. This article examines current methodologies in Uzbekistan, identifies gaps, and proposes strategies for enhancement, integrating technological advancements, interdisciplinary approaches, and active learning techniques. By refining these methodologies, teacher training programs in Uzbekistan can better prepare educators to meet the demands of contemporary language education.
