In any professional community, there are certain rules of behavior, etiquette. The same thing exists in the scientifc text, in monographs and articles. In our opinion, etiquette is manifested in the presence in the text of epigraphs, dedications, gratitude, the author's self-name and address to readers, in footnotes, the interpretation of terms, the precise indication of sources of citations and sources listed in the list of references, reference to predecessors. It is the means of expressing speech etiquette that this article is devoted to.
