An instructional guide emphasizes analyzing the sentence as the primary unit of grammar, treating grammar as a study of thought and communication rather than a catalogue of rules. It defines propositions, subjects, and predicates, then classifies sentences by structure and form. Chapters present methods for analyzing clauses and phrases — adjective, substantive, and adverbial clauses of time, place, manner, cause, purpose, condition, concession, and degree — alongside treatments of infinitive, participial, gerund, prepositional, and appositive constructions. The text also examines objects, complements, adverbial nouns, modifiers, ellipsis, independent elements, and compound and complex sentence formation, with exercises and examples for classroom practice.
