Arab world

The Arab world, formally the Arab homeland, also known as the Arab nation, the Arabsphere, or the Arab states, comprises a vast group of countries, mainly located in Western Asia and Northern Africa. While the majority of people in the Arab world are ethnically Arab, there are also significant populations of other ethnic groups such as Berbers, Kurds, Somalis and Nubians, among other groups. Arabic is used as the lingua franca throughout the Arab world.
