Syrian Americans
While some may speak the formal Literary Arabic, many Syrians speak Syrian Arabic, a dialect which belongs to the Levantine Arabic family of dialects. There are also sub-dialects in Syrian Arabic; for example, people from Aleppo have a distinct and distinguishable accent, one that differs considerably from that of people from Homs or Al-Hasakah. Syrians can usually comprehend and understand the dialects of most Arabs, especially those who speak any form of Levantine Arabic.
