Eponyms occupy a significant place in scientific terminology as linguistic units derived from the names of scholars, researchers, or historical figures who made substantial contributions to the development of science. They serve not only as nominative tools but also as markers of scientific heritage, continuity, and intellectual recognition. This abstract examines the role of eponyms in the formation and standardization of scientific terminology, highlighting their cognitive, cultural, and communicative functions. Particular attention is given to the principles governing their development, including motivation, internationalization, stability, and adaptation to modern terminological systems. The study emphasizes that while eponyms enrich scientific language, their use requires systematic regulation to ensure clarity, consistency, and intercultural comprehensibility in contemporary scientific discourse.
