Dialectal Arabic refers to the various regional forms of the Arabic language spoken across the Arab world. Unlike Modern Standard Arabic, which is used in formal settings, dialectal varieties are used in everyday conversation and can differ significantly from one region to another. These dialects can be grouped into several main categories, including Egyptian Arabic, Levantine Arabic, Gulf Arabic, and Maghrebi Arabic. Each dialect has its own unique vocabulary, pronunciation, and grammar, making them distinct from each other and from the standard form of the language.
