The main goal of the article is to share the experience of using the resources of the online Oxford English Dictionary (OED) in teaching English for Specific Purposes (ESP) to the students of chemistry, this problem being important in the context of distant learning. In practical terms, research projects carried out on the OED material allow students to obtain systematic data on the etymology, pronunciation, semantics of professionally-oriented terms, homonyms, polysemantic words and phraseological units. This knowledge is significant for the correct use of lexemes in students’ oral and written speech.
Key words: English for Specific Purposes (ESP), student research project, electronic dictionaries, Oxford English Dictionary, names of chemical elements.
