Hundreds, Thousands, Millions, and Billions

Large Egyptian numbers are built from lexical blocks, not by translating English one word at a time. Hundreds have one form when they stand alone and another directly before a noun; ألف cycles through singular, dual, and plural; and مليون and مليار behave more like fixed scale labels in everyday Cairo speech.

This page gives the mainstream urban Cairene (informal) system. Formal MSA spellings such as مائة, case endings, and formal plural choices occur in official writing and careful code-switching, but they are not silently mixed into the conversational paradigm.

Rule 1: Hundreds Have Standalone and Prenominal Shapes

The ordinary Cairene words are lexicalized compounds and must be learned as vocabulary. From 300 to 900, a standalone form ends in ـمية -miyya. Directly before a counted noun, the ending becomes ـميت -mīt. One hundred likewise contrasts مية with ميت.

Speakers and informal writers vary in how consistently they expose ـميت in the spelling of 400–900; the pronunciation is clearest when a noun follows. This page uses the explicit construct spelling in examples where it helps learners hear the boundary.

Masculine كتاب and feminine عربية are both singular. Hundreds do not trigger a productive gender contrast in the numeral; the counted noun keeps its lexical gender but appears in the singular.

Rule 2: ألف Behaves Like a Counted Noun

The word ألف “thousand” has a singular, a dual, and a special plural تلاف after 3–10. From 11,000 upward, it returns to singular ألف after the number.

Notice two noun layers in the second example. ألف is singular after 11, while final طالب is also singular after the complete large number. English pluralizes thousand only selectively and always pluralizes students; Egyptian distributes number differently.

Informal spelling may fuse the fast pronunciation as تلاتلاف, but the transparent house spelling here is تلات تلاف. The words are pronounced tightly together in fluent Cairo speech.

Rule 3: Million and Billion Are Stable Scale Labels

Everyday Egyptian normally uses singular مليون and مليار after a preceding number from three upward. Exactly two uses the dual مليونين/مليارين. Formal writing may prefer plural ملايين/مليارات in contexts where colloquial speech keeps the scale label singular.

The dual مليونين expresses exactly two million by itself; emphatic speech can add following اتنين. From three upward, use the long numeral followed by the stable label: تلاتة مليون، أربعة مليار.

Rule 4: Combine Large Blocks from Largest to Smallest

Large numbers normally move from the largest block toward the smallest. Each internal two-digit block still uses unit-before-decade order.

The overall sequence is thousand → hundred → twenty-five, but twenty-five itself is spoken “five and twenty.” The final counted noun جنيه remains singular.

Because the number stands alone here, the final hundred block is تلتمية, not prenominal تلتميت.

Rule 5: Prices and Other Measures Keep the Final Unit Singular

A price question makes the complete number one answer. The currency label comes once, after the entire number.

This last pair supplies both masculine صندوق and feminine شنطة under the same prenominal-hundred rule. For the internal 21–99 block, review coordinated compound numbers.

Careful and Fast Speech

Careful speech keeps boundaries audible: talat talāf, alf wi-mītēn. Fast speech compresses them toward talattalāf and alf w-mītēn. That compression is pronunciation, not a new word order. The ordinary spelling in this guide keeps magnitude words visibly separate.

Register and Variation

Newsreaders and official documents may use مائة، ثلاثمائة، ثلاثة ملايين with formal pronunciations and syntactic choices. Educated Cairene speakers can code-switch into those forms by topic and audience. Alexandrian, Delta, Upper Egyptian, Bedouin, age, and community varieties show phonetic and lexical variation, especially in the internal vowels of compound hundreds. The forms above are the explicit Cairo baseline, not a judgment that formal or regional forms are incorrect.

Common Mistakes

Using a plural counted noun after a hundred

Building the hundred as separate ordinary words

Using the long unit before تلاف

Reversing the scale label and its multiplier

Key Takeaways

• Use standalone مية/تلتمية but prenominal ميت/تلتميت.
• ألف، ألفين، تلاف، ألف cycle with one, two, 3–10, and 11+.
• Everyday Cairo normally keeps مليون and مليار singular after three and above.
• Build from larger blocks to smaller ones, while 21–99 internally remain unit + و
  • decade.
• The final counted noun after a large number is normally singular and carries no MSA case ending.
