SUMMARY
This paper concerns the converb forms expressing simultaneity in Izhma Komi, Northern Khanty and Moksha belonging to the Finno-Ugric group of languages. The existing typological classifications of temporal relations and simultaneity relations in particular either are not detailed enough or lack rigorous criteria and thus appear not to be sufficient for understanding the usage and the distribution of temporal converbs. This study attempts to build a more detailed typological classification of simultaneity relations which accounts for the data of the languages under consideration. The analyzed parameters of variation include the viewpoint aspect of the events, clause modification type, givenness of the conveyed information and the pragmatic type of the predicate. Special attention is paid to the discourse-pragmatic properties of the forms which bring new insights into the discussion.
