Abstract
This study focused on structural and semantic changes in Kazakh borrowed vocabulary adaption. The study examined how imported concepts were absorbed into Kazakh, altered by the national linguistic system, and contributed to current terminology. Various linguistic methodologies were used, including historical and contemporary text analysis, structural and comparative term analysis, and hybrid word classification. The study covered both present and historical English, allowing vocabulary changes to be tracked. The findings showed that complicated historical and cultural processes in active intercultural exchanges caused Kazakh terminology hybridisation. The Greco-Latin, Persian, and Arabic languages enriched Kazakh lexicon with science, religion, culture, and daily life concepts. Phonetic, morphological, and visual changes were made to borrowed terminology to make them useful and conform to Kazakh linguistic norms. The study showed that hybrid terms are crucial to borrowing integration.
