The ability to speak and write in strict scientific language plays an essential role in the work of teachers of technical universities. In addition, in a market economy, mastering business rhetoric and its effective application can be of significant and sometimes decisive importance for the growth of prestige, competitiveness and creative potential of a young specialist. So, rhetoric (let us conditionally call it technical) can be spoken (oral) and written. From the first days of higher education, when a student starts listening to lectures, he/she is already introduced to rhetoric. Significant opportunities for teaching students oral technical rhetoric are provided by communication with the teacher during interviews, colloquiums, laboratory practicals, preparation of speeches at conferences of student scientific society or course and diploma projects. No less important means of familiarizing students with literate technical written language is teaching them to take notes on lectures. Rhetoric contributes to the improvement of speech culture, and thus culture in general.
