Streszczenie:
Univerbation and substantivation belonging to active ways of the modern substantive word-formation, differed in their efficiency already in the Old Russian language. Both these processes were characteristic for different genre and stylistic groups of the Russian literary language. In the Old Russian language there was an univerbation and substantivation formation as ways of word-production with the background of destruction of semantic syncretism, of the formular (syntagmatic) structure of the text and strengthening of language paradigmatics.
