It takes two, baby! CAUSE and the prerequisites for eventivity

This paper discusses two major classes of stative verbs: those displaying a systematic stative/eventive ambiguity, and those allowing for a stative reading only. By examining the possible lexical-semantic structures for these verbs, the paper argues that it is the presence of CAUSE that enables the ambiguity. If CAUSE is absent, no other aspectual operators may be inserted, and no eventive reading can be created. This hints towards the idea that CAUSE is a prerequisite for the eventive reading, and that CAUSE is the only way natural language allows for two sub-events to be expressed within a single verb.
