In the Altai variety of Tuvan (a Western variety spoken in Tsengel district, Bayan-Ölgii, Mongolia), the converb in -y heads non-finite syntactically subordinate clauses and its subject generally corefers with the subject of the superordinate clause, i.e. it is a same-subject converb (SS-converbs). Part-whole relations between the subject of the converbial clause and the subject of the superordinate clause also license SS-converbs. Possession must be overtly coded on the possessed subject.
