Introduction. In the contemporary multilingual context of the Russian Federation, where Russian coexists with other indigenous languages, the Kalmyk language is of particular research interest. Disruptions in intergenerational transmission and asymmetric proficiency in Kalmyk and Russian contribute to code-switching and mixing, affecting the language’s vitality and speakers’ linguistic attitudes. Objectives. This study examines the attitudes and use of Kalmyk across age groups and explores intergenerational dynamics of code-mixing in relation to language attrition. Materials. Data were collected through a survey of 108 Kalmyk speakers in the Republic of Kalmykia (November 2024), categorized into three age groups. Results. Significant intergenerational differences were observed. The older generation actively uses Kalmyk in daily life, demonstrates tolerance toward linguistic errors, and supports younger speakers. The middle generation exhibits irregular use of Kalmyk language and concerns over “language purity,” while youth use Kalmyk minimally, adopting a neutral stance. Code-mixing occurs across all groups but for different reasons: older speakers – bilingual habits and expressive purposes; middle generation – language preservation; youth – habitual use with some conscious efforts on Kalmyk language inclusion. Most respondents consider Kalmyk prestigious despite its reduced functional domains. Conclusions. Code-mixing constitutes a stable communicative strategy with both pragmatic and symbolic functions. Kalmyk continues to serve as a marker of identity, and intergenerational differences in language attitudes reflect ongoing language attrition. Introduction.
