The Counted Noun (Tamyīz)

The counted noun (tamyīz) takes a different form depending on the number:

• 3-10: plural: ثلاثة كتب (three books), ست مدن (six cities).
• 11-99: singular in the accusative. Masculine nouns add ا: عشرون طالبا (twenty students), بخمسين درهما (for fifty dirhams). Nouns ending in ة do not change: ثمانون سنة (eighty years).
• كم (how many) works like 11-99: كم كتابا اشتريت؟ (How many books did you buy?)
• 100, 1000 and their multiples: singular in the genitive: مئة مسجد (a hundred mosques), ألف كتاب (a thousand books), مئتا عامل (two hundred workers), ثلاثة آلاف شخص (three thousand people).

The gap shows the noun in another form: write the form the number needs.
