Classical foreign words and phrases are expressions borrowed from ancient or traditional languages—especially Latin and Greek, but also French, German, Italian, and others—that are commonly used in English, often without translation.
These phrases are called “classical” because they originate from classical languages and cultures that had a strong influence on Western education, law, science, philosophy, and literature.
