This article considers the effectiveness of using proper names in teaching a professional foreign language English for Specific Purposes (ESP) to students of various agricultural specialties. In modern studying programs, almost no attention is paid to the study of the proper name, which occupies an essential place in the vocabulary of any language, reflecting important aspects of its history and culture development.

The study of writing and culture relicts, data from etymological dictionaries, local history and literature, research of groups of zoonyms, toponyms and anthroponyms determine the necessity of developing and applying new methodological techniques and technologies.

In preparing this article, such methods of scientific analysis and generalization were applied as descriptive, methods of etymological analysis, as well as elements of comparative and typological analysis.
