In this article, we will try to show the use of cliched formulas in teaching Russian to a national audience, namely, specialists in the economic sphere. We have taken as a basis the principle of interconnected learning when teaching Russian to Kazakh-speaking students of Economics in the system of trilingual education. It should be noted that the principle of interconnected learning involves a coordinated selection and presentation of educational material. This principle is significant because each concept is considered from the perspective of three languages that provide greater efficiency in understanding, understanding and memorizing scientific concepts.

In Kazakhstan, as is known, trilingual education is provided. Language contacts of Kazakh, Russian and English languages occur in our country in the sphere of economy and education. As a result of this process is the transposition (a positive impact of languages) and interference (negative influence of the native, first language learning, second, language) and languages in General possible convergence (convergence or coincidence of two or more linguistic entities). As you know, a competitive specialist should know not only the features of the socio-cultural and sociolinguistic situation in the country, but also the features of perception, understanding and generation of speech in the second and third languages, be competent in the field of interrelated language learning.
