The article focuses on the emerging cognitive terminology in linguistics, the cognitive approach to
the term, and the problems of cognitive terminology in the works of A. Baitursynuly. The article identifies three criteria for the professional linguistic personality of A. Baitursynov. The professional linguistic personality of a scientist is analyzed according to 1) professional knowledge in the subject words used by a professional linguistic personality; 2) keywords in professionally oriented communication, personal-personal meanings reflected in the topics and problems raised; 3) motivational-pragmatic criterion. The first dimension is determined by the content of the cognitive structure
associated with personality cognition. The second dimension is reflected in the problems and topics raised by A. Baitursynov, personal conclusions and thoughts. The scientist's personal views on the literacy of Kazakh children, the compilation of the Kazakh alphabet, auxiliary tools written for Kazakh teachers, the order of writing, the principles of creating subject words, the purity of the language, the art of words, and the ideas of enlightenment express his personal views. The third motivational-pragmatic dimension is reflected in the samples of folklore analyzed in the works of the scientist. His inclusion in scientific discourse of Enlightenment ideas in the works of poets Abai, Shakarim, Magzhan, etc.determines the spiritual and communicative level of the professional linguistic personality of the scientist. It is proved that the words of the subject are a unit of professional linguistic personality discourse. Features of the term study in the cognitive-communicative and pragmatic aspects are indicated. According to the works of A. Baitursynuly, it is
analyzed that the term is a special cognitive and informational structure, represented by a specific linguistic form of professional and scientific knowledge accumulated by a person throughout his life. The article discusses the problem of language and education in cognitive terminology. It is proved by concrete examples that the term is a name of a scientific concept resulting from the activities of a researcher or a specialist in a certain field of science. An important
place in both naming the term and establishing its definition is occupied by the complex thought process of a specialist in a special field. The article analyzes the traditional naming function of the term, the activity of consolidating new knowledge, and the activity of guiding.
