This tool spells any whole number into Modern Standard Arabic (الفصحى) words — the form used in writing, contracts and formal documents across the Arab world. It is useful for invoices, cheques and teaching, and runs entirely in your browser.
Why Arabic number spelling is grammatically complex
Spelling numbers in Arabic is significantly more intricate than in most European languages, for reasons rooted in classical Arabic grammar. Understanding these rules helps you verify the output and use it correctly in formal documents.
Arabic has a grammatical dual. Whereas English has singular (“one thousand”) and plural (“thousands”), Arabic has three forms: singular, dual, and plural. Two thousand is not “two thousands” but the dual form: ألفان. Two million is مليونان. This tool handles dual forms correctly for 2 in each scale group.
Plural scale words apply only to 3–10. The plural آلاف (thousands), ملايين (millions), and مليارات (billions) is used after numbers 3–10. For 11 and above, the singular scale word is used again: eleven thousand is أحد عشر ألفاً.
Units and scale words do not always agree in gender. In classical Arabic, the number word and the noun it counts must agree in gender, but the agreement follows a counterintuitive rule in Arabic (sometimes called “polar agreement”): the masculine numbers are used with feminine nouns and vice versa. For abstract written numerals in documents and invoices, the common masculine form used here is the standard convention.
How it works
The number is split into groups of three digits (units, thousands, millions, billions). Each group of up to three is spelled with the standard hundreds, tens and units words, and then joined to its scale word — ألف (thousand), مليون (million), مليار (billion). Arabic chooses the scale word’s form by count: the singular for one, the dual (ألفان, مليونان) for two, and the plural (آلاف, ملايين, مليارات) for 3-10. Groups are joined with the connector و, and the output reads right-to-left.
Worked example
The number 1234 breaks into 1 thousand and 234:
| Part | Arabic |
|---|---|
| 1000 | ألف |
| 200 | مئتان |
| 34 | أربعة وثلاثون |
Joined with و, the result is ألف ومئتان وأربعة وثلاثون.
Practical uses for this tool
Cheques. Arabic-script cheques require the amount in words on the payee line, just as English cheques do. The output of this tool follows the formal written convention expected by banks across the Arab world.
Invoices and contracts. Written numbers in formal Arabic business documents use Modern Standard Arabic, not colloquial dialect. Contracts, purchase orders, and official receipts typically spell out amounts.
Language learning. Seeing how numbers are constructed reveals the structure of Arabic grammar — the dual, the polar agreement rule, the grouping connectors. The output can serve as a learning reference alongside grammar study.
Teaching. Teachers of Arabic can use the tool to generate number-spelling exercises quickly across a range of values.
What the tool does not cover
This tool converts whole numbers only. For monetary amounts with fractional units (such as Saudi riyals and halalas, or Egyptian pounds and piastres), convert the whole part and add the minor unit name separately. Ordinal numbers (first, second, third) and fractional numbers require different Arabic constructions not covered here.
