Error Messages That Work in English and Arabic
Good error messages do three things: they say what went wrong in plain language, they keep whatever the user typed so nothing is lost, and they tell the user exactly what to do next. In a bilingual app, the same message must work in English and Arabic without sounding like a literal translation. The most common failure is treating all errors as one category. Wrong credentials and a service outage need different words, different tones, and different recovery paths.
Separate the error categories before you write a word
Start by listing the distinct failure states your app can produce. At minimum: invalid credentials, expired session, missing or malformed input, network unreachable, service temporarily unavailable, and permission denied. Each one has a different cause and a different fix. If your code throws a generic error object and the UI renders one string, users cannot tell whether they typed the wrong password or the server is down.
Map each state to a specific message key. A wrong password should say the credentials were not recognized and invite a retry or password reset. A service outage should say the service is temporarily unavailable and suggest trying again later. Never reuse the same wording for both. In Arabic, the distinction matters just as much: بيانات الدخول غير صحيحة is not the same as الخدمة غير متاحة مؤقتاً.
Preserve input and make recovery obvious
When a form submission fails, keep every field the user filled in. Clearing a password field is acceptable for security, but wiping an entire registration form because the email was already taken is hostile. Preserve the input, highlight the field that needs attention, and place the error message next to it, not in a distant banner.
The next action should be a verb the user can perform: try again, reset your password, check your connection, contact support. Avoid vague phrases like an error occurred or something went wrong. In Arabic, use clear imperatives: حاول مرة أخرى, أعد تعيين كلمة المرور, تحقق من اتصالك بالإنترنت. If the action is not something the user can do, say who can help and how to reach them.
Write for Arabic as an original, not a translation
Arabic error messages often read as awkward because they are translated word for word from English. Build the Arabic copy from the same intent, not the same sentence structure. English tends to be direct and short; Arabic can be equally direct but often benefits from a slightly fuller clause that sounds natural to a native reader.
Pay attention to right-to-left layout. Error icons, progress indicators, and inline validation marks should sit on the correct side. Numbers and Latin brand names inside Arabic text need bidirectional isolation so they do not scramble the surrounding words. Test with real Arabic content, not placeholder text, because placeholder text hides wrapping and alignment problems.
A concrete test you can run before release
Suppose your app has a login screen. Turn off the device network and attempt to log in. The message should say the connection is unavailable and offer a retry, not blame the credentials. Then enter a wrong password with the network on. The message should say the credentials were not recognized and offer a password reset. If both cases show the same text, the error handling is not ready.
Run the same test in Arabic and check that the message reads naturally, that the layout does not break, and that any numbers or Latin text stay in the correct order. This test takes minutes and catches the most common bilingual error-message failures before users see them.
Tradeoffs and maintenance
More specific messages mean more strings to translate and maintain. A small app may not need a unique message for every possible server response, but it should at least distinguish user-correctable errors from system errors. Grouping too aggressively brings back the original problem: users cannot tell what to do.
Plan for updates. Error copy changes as your product changes, and Arabic and English versions can drift apart if one is edited without the other. Keep both languages in the same source file, review them together, and treat a missing translation as a bug, not a cosmetic issue. Over-the-air updates can push corrected copy quickly, but native changes still require a store release, so get the wording right before you ship.
