The purpose of this adviser hour held on 19th of September in 2023 and organized by adviser A.A. Amirbayeva was to familiarize students with the fact that every citizen of the Republic of Kazakhstan has the right to use their native language, to freely choose the language of communication, education, training and creativity. In the 20th of January in 1998 the Decree of the President of the Republic of Kazakhstan N.A. Nazarbayev was issued, where September 22 was declared as the Day of Languages of the Nationalities of the Republic of Kazakhstan. Every year on September 22, Kazakhstan celebrates the Day of Languages. This is a common holiday for all peoples of Kazakhstan. The multinational holiday of languages is based on the following idea: every language is part of the spiritual heritage of all humanity, and every culture is an invaluable contribution to world civilization. There are 130 nationalities living in the Republic. Moreover, each of them has a unique spiritual and material culture, its own history, traditions and customs. During the adviser hour, students learned about the features of some languages of the nationalities and discussed the traditions of different countries. Students expressed their respect for their native language and the languages of other people. Moreover, the issue of linguistic discrimination was discussed solely.
