The article provides a comprehensive analysis of inconsistencies and variations observed in the orthographic norms of compound words in the modern Kazakh language. The research material consists of 54 lexical items, including 18 names of animals, 12 names of plants, 14 medical terms, and 10 words representing diverse semantic and morphological models. The study employs comparative analysis, phonetic-pattern analysis, structural-morphological and semantic modeling, as well as a comparative examination of orthographic dictionaries and normative reference sources. The findings reveal that approximately 30% of the compound words under consideration appear in two or more parallel written forms across different orthographic dictionaries and reference publications. Major problematic areas of Kazakh orthography identified in the study include the inconsistent application of vowel harmony rules, the lack of reflection of phonetic assimilation in writing, discrepancies between pronunciation and orthographic representation, the violation of morphological integrity, and the presence of unsystematic spelling patterns in the names of animals, plants, and medical terms. The results underscore the necessity of revising the spelling conventions of compound words in accordance with the internal linguistic laws of Kazakh, its natural phonetic structure, and its agglutinative nature. The conclusions presented in the article hold practical significance for the development of orthographic rules based on the new alphabet, the updating of orthographic dictionaries, and the scientific justification of orthographic directions within state language policy
