Abstract This article examines a new direction in the digitalization of Kazakh linguistics–the development of a six-language parallel subcorpus based on literary texts. The research focuses on a multilingual database composed of texts in Kazakh, English, Turkish, Uzbek, Uyghur, and Azerbaijani. Its structural organization, metadata annotation system, and principles of paragraph-level alignment are described. The research material is based on a multilingual corpus compiled from Volume I of M. Auezov’s novel-epic The Path of Abai. The study provides a comparative analysis of syntactic, semantic, and pragmatic equivalence across translations in different languages. Particular attention is given to complex sentences, dialogic structures, forms of address and endearment, ethnomarked units, literary and poetic vocabulary, figurative expressions and idioms, as well as interjections. These elements are systematically classified, and their cross-linguistic equivalence levels are identified. The results demonstrate a high level of structural and semantic equivalence among Turkic languages, while English translations tend to prioritize functional and pragmatic adaptation. Furthermore, the six-language parallel subcorpus of the Kazakh language is shown to be a valuable resource for applied research in corpus linguistics, translation studies, comparative linguistics, and digital humanities. The scientific novelty of the study lies in the first-ever proposal of a six-language parallel subcorpus model in Kazakh linguistics based on literary texts, along with a comprehensive description of its metadata annotation, alignment, and analytical principles. The findings can be applied in corpus linguistics, translation studies, comparative linguistics, and the development of linguistic databases for artificial intelligence systems.
