This article provides a comprehensive analysis of the

pedagogical and psychological aspects of developing lexical

skills in future English language teachers within a modern,

innovative educational environment. It emphasizes the intrinsic

connection between language and thought, interpreting lexical

skill not merely as word selection and usage, but as an integral

component of cognitive and speech processes. The article

scientifically distinguishes between expressive (productive) and

receptive lexical skills, elucidating their roles in verbal

communication. Additionally, it examines the fundamental

characteristics of lexical skills, such as automaticity, stability, and

adaptability, highlighting their importance in the teaching

process. The paper outlines effective strategies for expanding

vocabulary and reinforcing lexical competence in future teachers

through the utilization of modern information and

communication technologies and interactive methods. It also

addresses the conditions necessary for overcoming negative

interference between the target language and the mother tongue,

and for developing strong foreign language proficiency. The

article systematically explores the stages of lexical skill

formation, including the guiding-preparatory, stereotyping-

situational, and variable-situational phases. Intended for

philology students, postgraduates, and practicing teachers, this

work serves as a valuable resource for organizing engaging and

meaningful lessons and for enhancing the professional

qualifications of educators.
