Geographers define Arabs as people who speak the Arabic language and who usually, though not always, practice the Islamic religion.
About 90 percent of the people who live in Middle Eastern countries and northern Africa are Arabic.
Non-Arabs include Iranians, who speak Farsi (the ancient Persian language); Turks, who speak Turkish; and Kurds, who speak Kurdish.
Arabs make up most of the populations of Algeria, Egypt, Iraq, Jordan, Lebanon, Libya, Morocco, Saudi Arabia, Sudan, Syria, Tunisia, and Yemen.
Arabic, the main unifying feature among Arabs, is a Semitic language that originated in Arabia.
The earliest documented use of the word “Arab” which defines a group of people come from the 9th century B.C.
