Languages of Egypt
Egyptian Arabic is the commonly spoken language, and is occasionally written in Arabic script, or in Arabic chat alphabet mostly on new communication services.
Sudanese Arabic
Sudanese Arabic is similar to Egyptian Arabic. While it does not share some of the characteristic properties of northern Egyptian dialects (like that of Cairo), Sudanese Arabic is particularly close to central and southern Egyptian or Sa'idi Arabic. It is also closely related to Hejazi Arabic.
