Abstract. This study examines intercultural language development using Turkish and Uzbek as case studies. Both languages, belonging to the Turkic family, share significant lexical, grammatical, and phraseological similarities, which facilitate pedagogical processes. Additionally, culturally specific expressions and customs—such as “Kolay gelsin” and “Labbay”—enhance mutual understanding. This practice fosters intercultural competence, empathy, and inclusivity. A project-based teaching approach effectively integrates both language and culture. The annotation concludes that developing multilingual competencies is not only a matter of linguistic similarities but a holistic process that promotes cultural sensitivity, respect, and inclusive communication.
