<![CDATA[This study also highlights the role of Arabic Fusha as a medium of formal communication adhering to grammatical rules, and Ammiyah as a flexible form reflecting local cultures. The analysis aims to enhance understanding of language variation in social and functional contexts, specially for Arabic Fusha and Ammiyah. Which is using a qualitative descriptive approach. Data were collected through literature studies by reviewing relevant literature, such as books, journal articles, and official documents related to Fusha and Ammiyah Arabic in formal and informal contexts.The results of the study obtained are that spoken language tends to be used in informal situations, with the characteristics of spontaneity, the use of idioms, and nonverbal signs. In contrast, written language is more often used in formal contexts that demand complex sentence structure, standard vocabulary, and objectivity. Examples of various spoken and written languages in Arabic fusha are the variety of speech in the state speech of King Faisal of Saudi Arabia related to socio-politics and the variety of written Arabic Fusha in a written letter about the meeting between high-ranking state officials, namely the Prime Minister of Qatar and the Minister of Foreign Affairs of Singapore. Then examples of the variety of speech and writing in Ammiyyah Arabic, namely the variety of speech in one of the video clips on social media about snippets of stories of a man's daily activities on social media Youtube, and the variety of written languages in Ammiyah Arabic can be found in one of the conversation clips with the theme "in the pharmacy" in a book that specifically uses Ammiyyah Arabic.]]>
