ABSTRACT
In Chapter 1 we generalised about the kinds of things which we talk about by introducing the notion of situation types. We recognised three broad types of situation — STATE, EVENT, ACTION — with various subtypes. States, events and actions are represented in the grammar of the language by verbs. When we use a verb in a sentence there are a number of additional pieces of information which we may or must specify. For example, we have to choose whether to use a verb in the present tense or the past tense (see Chapter 1); it must appear in one or the other. In this chapter we are going to look at these specifications of states, events and actions. They have broadly to do with the setting of situations in time, and with the possibility or necessity of situations.
