The Arab world (Arabic: اَلْعَالَمُ الْعَرَبِيُّ al-ʿālam al-ʿarabī), formally the Arab homeland (اَلْوَطَنُ الْعَرَبِيُّ al-waṭan al-ʿarabī), also known as the Arab nation (اَلْأُمَّةُ الْعَرَبِيَّةُ al-ummah al-ʿarabiyyah), the Arabsphere, or the Arab states, comprises a large group of countries, mainly located in West Asia and North 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.
The Arab world is at its minimum defined as the 19 states where Arabs form at least a plurality of the population. At its maximum it consists of the 22 members of the Arab League, an international organization, which on top of the 19 plurality Arab states also includes the Bantu-speaking Comoros, and the Cushitic-speaking Djibouti and Somalia. The region stretches from the Atlantic Ocean in the west to the Arabian Sea in the east, and from the Mediterranean Sea in the north to the Indian Ocean in the southeast. The eastern part of the Arab world is known as the Mashriq, and the western part as the Maghreb.
