The Place of Motion Verbs within the Aspectual Class of Activity Predicates

One of the challenges in applying Zeno Vendler’s well-known aspectual classification of verbs (1957) concerns the identification of members of the class he termed activity. This class name has been translated into Bulgarian as действие and/or дейност, but it can also encompass motion verbs – particularly those denoting the spatial movement of an animate agent. This raises the non-trivial question of how to distinguish between motion verbs, action verbs, and activity verbs in a principled way, with the aim of identifying a possible “common denominator” or reference point among them. Such a reference point could justify grouping them within a single class – if this can be achieved in a non-contradictory way. The article offers a discussion intended to clarify the structure of the activity class, based on the postulate that a key to its interpretation lies in a precise analysis of the thematic group of motion verbs.
