The introductory Latin courses are designed to teach the student to read and to translate increasingly more complex passages from Latin literature. The passages provide insights into ancient Roman thought, which is still exercising influence today. The approach is a traditional one and involves the study of grammatical structures, knowledge of which proves useful in the study of other languages, including English. Since a great number of English words are derived from Latin, the student's English vocabulary is enlarged. Of course, the student learns the meaning of common Latin expressions, such as et cetera and habeas corpus.
