The materials of the Kazakh language, published in the «The experience of the dictionary of Turkic dialects» by V. V. Radlov, published in 1888-1911 in St. Petersburg in four volumes and eight books, are the main object of this study. It is well known that each language is subject to change under the influence of internal linguistic processes and external factors. In this regard, it is doubly valuable and significant to consider the composition and structure of the Kazakh vocabulary published in the common Turkic dictionary of the 19th century from the point of view of modern science. The main purpose of the study is to study the grammatical characteristics of Kazakh vocabulary, namely, the disclosure of phonetic, morphological and word-formation features of words. Also, the principles of solving the problems of the alphabet and graphics, classification of sounds, the law of vowel, vowel harmony proposed by the famous scientist-encyclopedist of the 19th century are subject to scientific analysis. The study uses methods of collecting, selecting, systematizing language material, as well as descriptive, statistical, and comparative methods of analysis. The results of the study and the presented recommendations make a certain theoretical contribution to the study of the history of the Kazakh language, historical lexicology and lexicography, and can also be useful in the practice of teaching the history of the Kazakh language.
