Abstract: The article discusses the concept of educational competence, the component composition of foreign language communicative competence and the content of teaching the grammatical side of speech on the material of pronouns of the German language. The grammatical speaking skills presented at the center for research analysis are a means of forming communicative competence. Knowledge of grammatical rules is the basis for language proficiency. The organizing role is given to grammar, which is necessary for students to construct oral statements and understand foreign-language special texts. The article analyzes the features of teaching basic syntactic structures of the German language system, with methodically correct presentation of which students develop grammatical speaking skills. The need to pay great attention to the formation and development of grammatical competence is dictated primarily by the fact that communication in a foreign language is impossible without knowledge and ability to use words and phrases in their correct form in speech in accordance with the norms of the language being studied, as well as without the ability to recognize grammatical phenomena when perceiving someone else's speech.Possessive and demonstrative pronouns are the most difficult for the Russian-speaking audience to assimilate, due to the discrepancy between the forms of their formation and the different volume of their meanings in the contacting languages, which necessitates the use of methodological techniques to weaken the effect of interlanguage interference.
