The word "Arabia" originally meant "desert". "Arabian Peninsula" includes Syria and Sinai Peninsula. The word "Arabia" is recorded in ancient Greek books; Herodotus (484-425 BC), a famous Greek historian, also had unique views on Arabia, Palestine and Sinai Peninsula. The word "Arab" refers to the desert area of the peninsula, and "Arab" refers to "nomad" (Bedouin), which is symmetrical with "settler". '
About the seventh century later, with the expansion of Arab Muslims, most parts of West Asia and Central Asia were forced to speak Arabic.
