Important grammatical distinction: The four sentence types by function and the four by structure are the two foundational classifications taught in English grammar. Other sections organize sentences according to different grammatical, semantic, rhetorical, and stylistic properties; they are not all mutually exclusive sentence types. Optative sentences are also a traditional category in some grammar curricula, while modern English grammars generally analyze wishes and prayers through their grammatical form and communicative function.
