In the Western world, the Middle East is generally thought of as a predominantly Islamic Arabic community defined by frequent war. However the area encompasses many distinct cultural and ethnic groups, including the Arabs, Armenians, Assyrians, Azeris, Berbers, Chaldeans, Druze, Greeks, Jews, Kurds, Maronites, Persians and Turks. The main language groups include: Arabic, Armenian, Assyrian (also known as Aramaic and Syriac), Hebrew, Farsi, Kurdish and Turkish. The corresponding adjective is Middle-Eastern and the derived noun is Middle-Easterner.

Most Western definitions of the "Middle East" — in both established reference books and common usage — define the region as 'nations in Southwest Asia, from Iran (Persia) to Egypt'. Egypt, with its Sinai Peninsula in Asia, is often considered part of the 'Middle East', although most of the country lies geographically in North Africa. North African nations without Asian links, such as Libya, Tunisia and Morocco, are increasingly being called North African — as opposed to Middle Eastern (Iran (Persia) to Egypt-Asia) — by international media outlets.
