Sentence groups
Pages 28

A sentence group is a grammatical unit consisting of two or more sentences that center around one meaning. Sentence groups have three basic features. First, a sentence group contains two or more sentences, each having its own mood and intonation and each ending with a full stop, a question mark, or an exclamation mark in writing. Second, the sentences within sentence groups are related to each other in meaning; the whole sentence group focuses on one meaning. Third, the central meaning expressed by a sentence group can be summed up from the composite sentences in some cases; in others, it is directly expressed by one sentence in the group. For example,
