You are writing an invoice, a cheque or a contract and you need the amount spelled out in words rather than digits. The reason is simple: digits are easy to alter, words far less so. That is why banks and courts require amounts written in words.
Spelling amounts out in Arabic follows rules that are not obvious — gender agreement, dual forms, plural forms. A mistake can invalidate a document. This guide shows how to do it accurately inside your browser.
Why amounts are written in words
- Tamper resistance: adding a zero to "1000" is trivial; changing "one thousand" to "ten thousand" in prose is much harder.
- Removing ambiguity: some figures can be read more than one way; words settle the meaning.
- Legal requirement: many jurisdictions require amounts in words on cheques and promissory notes.
Why Arabic number spelling is hard
Unlike English, Arabic agrees the number with the counted noun in gender:
| Number | With masculine | With feminine |
|---|---|---|
| 1 | واحد | واحدة |
| 2 | اثنان | اثنتان |
| 3 | ثلاثة | ثلاث |
| 10 | عشرة | عشر |
| 100 | مئة | مئة |
Note the inversion: "ثلاثة كتب" (three books, masculine noun takes the form that looks feminine) but "ثلاث مجلات". This single rule is where most tools fail.

Local processing vs sites that want your amounts
| Criterion | In your browser (TaskDo) | A server-side site |
|---|---|---|
| Where the conversion happens | On your device | On a third party's server |
| The amounts you enter | Never transmitted | Usually logged |
| Your clients' privacy | Fully preserved | Their amounts sit on someone else's server |
| Works after page load | Works offline | Does not work |
The amounts you type are not abstract numbers — they are financial information about you or your clients.
Common spelling mistakes
- Ignoring gender agreement: "ثلاثة مجلات" is wrong; it should be "ثلاث مجلات".
- Wrong place order: "مئة ألف وخمسة وعشرون", not "خمسة وعشرون ومئة ألف".
- Omitting the currency: write the full phrase, and in Arabic add "فقط ... لا غير" to close the amount.
- Confusing million and billion: check the number of zeros before trusting the result.
- Not proofreading after pasting: pasting can corrupt Arabic numeral formatting.
Practical tips
- Write digits and words together: that is the accepted form on official documents.
- Close the amount: in Arabic, "فقط ... لا غير" prevents later additions.
- Check the last group of digits: most errors happen in the final three digits.
- Be consistent with currency names: use the same wording across all your documents.
