The present study deals with Russian secondary prepositions,
primarily focusing on multiwords. Secondary prepositions are units motivated by content words (nouns, adverbs, verbs), which may be combined with primary prepositions to form multiword prepositions (MWPs). Multiword prepositions perform the grammatical function of a preposition in a certain position of a syntactic structure in some contexts and can be a free word combination in others. This paper is devoted to analysis of the
use of secondary multiword prepositions with causal meaning. We analyze the repertoire of Russian MWP causal prepositions and describe their statistical representation in corpora.
