In the Todža variety of Tuvan (a Northeastern variety spoken around the Todzhinsky District of Tuva), there are several converbs, i.e. verb forms heading non-finite syntactically subordinate clauses. The subject of some converbs generally corefers with the subject of the superordinate clause, i.e. they are same-subject converbs (SS-converbs). Part-whole relations as well as some alienable possessive relations license the use of such converbs as well. Possession is overtly coded on the possessed subject.
