Konstantin Filatov (HSE University) More evidence for withdrawal effects: the case of Andic future marking

The talk is a revised and expanded version of the author's SLE 2025 presentation. It discusses the system of future grams in the Anchiq dialect of Karata (< Andic < Nakh-Daghestanian). The two core future forms can be described as marking future certainty vs. future possibility. While this type of system is not typologically uncommon, the diachrony of similar systems in closely related Andic languages (Godoberi and Bagvalal) poses a challenge for Bybeean source determination principle. This principle requires attributing all semantic differences between grams to differences between their grammaticalization sources. However, the principle can not fully account for the emergence of Andic future systems: the same source seems to have developed into the certain future gram in Anchiq, while having developed into the uncertain future gram in Godoberi. The talk presents a proposed diachronic scenario for the three Andic systems and explains their differences using the notion of withdrawal effects (as defined by Reinöhl and Himmelmann, 2017). This notion refers to a situation where the semantic network of an earlier gram is deformed by the «intrusion» of a newer one.
