3.2 Thematic-binding
f the thematic system is separable from the case-system, then we should see it
work independently. Williams (1994) has a
ued that forms of thematic-binding are
possible, indicating that they are a definable subsystem: one verb’s thematic
pro
ection, like Agent, can bind another ver
s Theme. In fact, they appear in the
nvisible pro
ections of nominalizations. We find that the difference is clearly
