Sa'idi Arabic (Sa'idi Arabic: صعيدى, locally: [sˤɑˈʕiːdi], Egyptian Arabic: [sˤeˈʕiːdi]; also known as Saidi Arabic and Upper Egypt Arabic) is the variety of Arabic spoken by Sa'idis south of Cairo, Egypt to the border of Sudan. It shares linguistic features both with Egyptian Arabic, as well as Sudanese Arabic. Dialects include Middle and Upper Egyptian Arabic. Speakers of Egyptian Arabic do not always understand more conservative varieties of Sa'idi Arabic.
Sa'idi Arabic carries little prestige nationally though it continues to be widely spoken, including in the north by rural migrants who have partially adapted to Egyptian Arabic. For example, the Sa'idi genitive exponent is usually replaced with Egyptian bitāʿ, but the realization of /q/ as [ɡ] is retained (normally realized in Egyptian Arabic as [ʔ]). Second and third-generation Sa'idi migrants are monolingual in Egyptian Arabic, but maintain cultural and family ties to the south.
