A practical, classroom-oriented guide that presents the principles of modern English usage through clear definitions, progressive lessons, and abundant exercises. It begins with sentences, subjects, and predicates, then treats parts of speech — nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions, and interjections — followed by phrases, clauses, sentence analysis, verb tense, mode and voice, agreement, and punctuation. Each topic is arranged pedagogically to build from simple to complex constructions, with drills and illustrative sentences to promote correct spoken and written habits and to develop students' ability to analyze and apply grammatical forms.
