A Student's Introduction to English Grammar

Here, we look at a number of syntactic differences that are used for different pragmatic purposes, specifically the characteristic but imperfect relations between the following clause types and speech acts: declarative clauses for making statements, closed interrogative clauses for asking closed questions, open interrogative clauses for asking open questions, imperative clauses for issuing commands, and exclamative clauses for uttering exclamations. These relations exist for both main and subordinate clauses.

Declarative clauses are the basic clause type that we’ve been describing so far. Interrogatives have a number of characteristics differences, including subject–auxiliary inversion and the use of interrogative words and fronting of the interrogative phrase in open interrogatives. The exclamatives are always marked by an initial exclamative phrase that begins with either adjective ‘what’ or adverb ‘how’. Imperatives characteristically lack a subject and use the plain form of the verb. We conclude with a brief description of a few minor clause types.
