Which Arabic should you use? Modern Standard Arabic vs dialects

Arabic is spoken by more than 400 million people across more than 20 countries, but it is not one single variety. Before you translate anything, you need to decide which Arabic your audience should read. The right choice depends on what you are publishing and who will read it.

Modern Standard Arabic (MSA)

Modern Standard Arabic, called al-fuṣḥā in Arabic, is the shared written language of the Arab world. It is used in newspapers, books, official documents, contracts, education, news broadcasts and most websites. Every educated Arabic speaker understands it, from Morocco to Oman.

Use MSA for:

• Contracts, policies, legal and financial documents
• Technical documentation, manuals and help centers
• Software and app interfaces that serve several countries
• Corporate websites aimed at the whole Arab world
• Healthcare and education content

MSA does not have to sound stiff. A good translator writes clear, modern MSA with a tone that suits your brand, from formal to friendly.

The main dialect groups

People speak their local dialect in daily life. The main groups are:

• Gulf (Khaleeji): Saudi Arabia, the UAE, Kuwait, Qatar, Bahrain and Oman
• Egyptian: widely understood across the region thanks to Egyptian film and TV
• Levantine (Shami): Palestine, Jordan, Lebanon and Syria
• Iraqi: Iraq
• Maghrebi (Darija): Morocco, Algeria, Tunisia and Libya, the most different from MSA

Dialects are mainly spoken, so they are rarely used for formal writing. They work well when you want to sound close and personal to one specific market.

Which one should you choose?

Content	Recommended Arabic
Contracts, policies, financial reports	Formal MSA
Manuals, help centers, documentation	Clear MSA
App or SaaS interface for several countries	MSA with a simple, friendly tone
Website for the whole Arab world	MSA
Marketing for one country	MSA with a local touch, or that country’s dialect
Social media and ads for one market	The local dialect often performs best
Video for a broad audience	MSA, or Egyptian for informal content
Customer support for one country	Simple MSA, with local words where natural

A practical rule

If your audience is in more than one country, or the content is official, technical or long-lasting, use MSA. If your content is short, emotional and aimed at one country, such as a social media campaign in Saudi Arabia, consider the local dialect or MSA with a local flavor.

Many brands combine both: MSA for the website, product and documentation, and a light local tone for social media and campaigns. This keeps the brand consistent while still sounding natural in each market.

Common mistakes to avoid

• Mixing dialects in the same text, which confuses readers
• Using a dialect for formal content, which can look unprofessional
• Writing heavy, old-fashioned MSA for marketing, which feels distant
• Translating slogans word for word instead of adapting them through transcreation
