Special sentence types
Speakers can use their language to perform various kinds of actions: making statements, asking questions, giving commands, offering wishes, blessings, curses; performing rituals and ceremonies (e.g. weddings), pardoning or sentencing a criminal, opening or closing a meeting, etc. Actions of this sort are often referred to as SPEECH ACTS. The first three of these (statements, questions, and commands) are the most common. People of all cultures need to perform these actions, and in most (if not all) languages we find distinct sentence patterns corresponding to each of them.
We suggested that the most basic kind of sentence structure is a simple statement, i.e. a DECLARATIVE clause. We will discuss questions, commands, and various other “non-basic” sentence patterns, focusing primarily on their grammatical structure rather than their pragmatic functions. Different languages use different combinations of morphological, syntactic, and phonological devices for marking sentence type, but certain patterns of similarity can be observed across languages, as we will see. Since we take the declarative to be the most basic sentence type, we will focus on those features which distinguish the other types from a basic declarative clause. We will begin with some brief comments about speech acts.
