The Arab world, also known as the Arab nation, the Arabsphere, or the Arab states, consists of the 22 Arabic-speaking countries which are members of the Arab League. These countries are located in Western Asia, North Africa, and the Horn of Africa, while the southernmost member, the Comoros, is an island country off the coast of East Africa. 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. Arabic is used as the lingua franca throughout the Arab world.
