Turkish grammaticalizes the cause-time relation expressed by the sonra clauses. The postposition sonra is generally taken to express a temporal relation of “priority in time” of the event of the embedded clause in relation to that of the matrix clause. However, the nature of the suffix on the verb of the clause embedded in the postpositional phrase distinguishes between the temporal and causal relation between the events of the matrix clause and the embedded clause. While constructions in which the embedded verb is marked with the suffix -DIktAn express the temporal relation between the two events, constructions in which the verb of the embedded clause is marked with the suffix -mAsIndAn encode the causal relation between the event of the matrix clause and that of the embedded clause.
