Fourth Form Latin completes the journey of Latin grammar by reviewing all material in First, Second, and Third Form, completing all verb forms for all four conjugations by studying for proficiency and mastery of nouns of all declensions, relative and interrogative pronouns, defective verbs, participles, infinitives and their use, gerunds and gerundives, deponent and semi-deponent verbs, irregular verbs, indefinite pronouns, comparison of adjectives and adverbs, purpose clauses (and the subjunctive mood), and sequence of tenses. Fourth Form continues to employ the identical format of First Form—an attractive, concise student text, systematic presentation in five units, extensive workbook exercises, and Latin sayings pertaining to classical history, literature, theology, philosophy, and art.
