This grammar is recommended for use in the 7th and 8th grades, as well as in high school. It is a comprehensive grammar in the classic sense, including four parts. Orthography: the study of letters, syllables, sounds and spelling that make up English words. Etymology: the study of words classified into parts of speech. Each part of speech is further studied according to classes, number, tense, mode, and other attributes which affect it as variously used in sentences. Syntax: the study of sentences, their elements, relations of parts, and so forth. It also includes the study of punctuation. Prosody: the study of accent, quality, and tone of language, as well as rhythms and measures as used in poetry. A more complete treatment of this topic than can be found in virtually all modern grammar books. When your students have studied such a comprehensive grammar, they can continue to use it for reference, checking on rules and definitions for a lifetime.
