The Tunisian Dialect, known as Derja, is a variety of Arabic spoken in Tunisia. It has unique phonetic and grammatical features that distinguish it from Modern Standard Arabic and other Arabic dialects. Influenced by Berber, French, and Italian, it reflects the country's diverse history and culture. Tunisian Dialect is primarily used in everyday conversation, while Modern Standard Arabic is reserved for formal settings, such as news broadcasts and literature. The dialect varies across regions, with different cities having their own local expressions and vocabulary, making it a rich and dynamic form of communication.
