Proper names as an integral part of a term in technical terminology (based on the terminology of measuring instruments)

Aim is to investigate the mechanisms of formation and peculiarities of functioning of term-eponyms in the names of measuring instruments, and to analyse their role in professional communication and scientific and technical discourse. Methodology. Using a continuous sampling method from the international electrical engineering dictionary, terms were selected that are the names of devices that contain a proper name. In the course of the research, the following methods were used: comparative method, lexicographic and etymological analysis. Results. The study identified the main models of formation of eponymic terms in the names of measuring instruments were identified, their high degree of terminology was proved, a stable connection between the eponymic part of the term and the measured value was established, confirming the importance of this terminology for the standardisation of professional communication. Research implications. The results of the study have practical value for terminology, lexicography and translation theory, and highlight the need to create specialised dictionaries of term-eponyms.
