We note (a) the well-rehearsed linguistic observation that eventualities can be referred to by using either noun phrases or sentences, and (b) the seductive ontological parallels drawn by Bach [1986] between eventualities and individuals. W e show how the mechanisms for knowledge representation and referring expression generation in an existing natural language generation system [Dale 1988, 1989] can be easily extended to combine these two insights in the generation of a wide variety of forms of reference to eventualities.
