"A strange variant of Russian čtoby-constructions: irreality and tense-marking"
In my paper, I discuss the choice of the verb form in constructions with a complementizer/adverbial subordinator čtoby. I show that while the situation is rather trivial in biclausal constructions, analysis of triclausal constructions where another clause is embedded under the čtoby-clause reveals a phenomenon which is not accounted for in any Russian grammatical descriptions. The marker imposes the past tense form not only to the verb in its clause, but also to the temporal clause which is embedded deeper. The existence of such an unusual construction results from both semantic and syntactic factors: namely, from the fact that the ‘unreal’ meaning carried by čtoby spreads to the temporal clause and from the syntactic properties of čtoby and kogda, the latter not imposing any formal restrictions on the verb form in the temporal clause.
