Saudi Arabia has officially launched its historic "National Policy for the Arabic Language," marking a major step to modernize and promote Arabic across the Kingdom. Approved by the Saudi Cabinet, the policy aims to make Arabic the primary language in business, science, education, and international relations. The policy is based on eight core principles, treating Arabic as a matter of "cultural security." Its five main objectives include reinforcing Saudi Arabia's global leadership in preserving Arabic, boosting its status in society, supporting its use in public and private sectors, attracting Arabic learners, and ensuring its use everywhere in daily life. Key principles of the policy include making Arabic the official language in all public institutions, with other languages allowed only if needed. Arabic will be the main language at all school levels, helping learners gain strong skills. It will be used widely in public life, including contracts, certificates, signage, and commerce. The policy promotes Arabic in scientific research and publishing. Media must prioritize Arabic content and provide translations when other languages appear. Businesses are encouraged to use Arabic in communications and customer engagement. Saudi Arabia also aims to strengthen Arabic's use in international conferences and diplomatic settings, with translation support as required. The cultural and artistic fields must increase Arabic presence in creative works, linking the language to national heritage. Practically, the policy means Arabic will become central in schools, universities, public institutions, and businesses. More academic research and media content will be created in Arabic. The policy supports Saudi Arabia’s cultural identity and pride while adapting the language for modern global use. On the world stage, it signals Saudi Arabia’s intent to lead Arabic language promotion and cultural diplomacy. This policy goes beyond administrative rules. It represents a strategic, cultural choice to safeguard Arabic and help it thrive in the modern world. It also fits with efforts in the Arab region to protect national languages amid globalization pressures. For Saudis and language learners, this policy promises a stronger, more vibrant future for Arabic in education, society, and international relations.
