Tundra Yukaghir has distinct converbs, i.e. non-finite verb forms heading syntactically subordinate clauses. Some of these are same-subject (SS) converbs, which require coreference between the subject of the converbial clause and the subject of the superordinate clause. SS-converbs are also licensed by two subjects which are in a part-whole relation with each other but which do not strictly corefer. In such constructions, the subject expressing the part must be overtly coded for possession with a possessive suffix.
