Аннотация:Degrees of derivational motivation in discourse perspective (Russian studies)The article is devoted to the analysis of the motivation scale of cognate words in Russian and weakening of their semantic links to the point of their complete desemantization. The author assumes that not only the root and stem but also formants can serve as motivators. Motivation by affixal model with a semantically empty root is typical of expressive colloquial derivation. The occurrence of low-motivated words in a language is also connected with historical pro-cesses in lexis, including the interaction of Old Russian with the Church Slavic language. The problem is being studied on the basis of composite words with a prepositive part благо-. The actualization of the inner structure of such composite words and strengthening of their moti-vation is shown in religious discourse, seen as a collective conceptualizer expressing a religious worldview. http://www.pracefilologiczne.uw.edu.pl/
