Mastering Arabic Numbers: Singular, Dual, and Plural

Numbers in Nouns: Singular, Dual, and Plural

Beyond "One and Many"

1. The Dual (اَلْمُثَنَّى) - Exactly Two

In Arabic, we don't just say "two books"; we change the word "book" itself. To make any noun dual, simply add the suffix -āni (ـَانِ) to the end.

• One book: كِتَابٌ (Kitāb)
• Two books: كِتَابَـانِ (Kitābāni)

Note: If the word ends in a Tā Marbūta (ة), it opens up into a regular 'T' before adding the ending (e.g., Sayyārah → Sayyāratāni).

2. The Plurals (اَلْجَمْعُ) - Three or More

Arabic has two main types of plurals: Sound Plurals (which follow a predictable pattern) and Broken Plurals (which change the internal structure of the word).

Sound Masculine

Add -ūna (ـُونَ)

مُدَرِّسٌ → مُدَرِّسُـونَ

(Teacher → Teachers)

Sound Feminine

Add -āt (ـَات)

طَالِبَةٌ → طَالِبَـاتٌ

(Student → Students)

 

The "Broken" Plural (جَمْعُ التَّكْسِيرِ)

Many common Arabic nouns don't follow the "Sound" rules. Instead, the "body" of the word breaks and reforms in a new pattern—much like "child" becomes "children" in English.

Singular	Broken Plural	Meaning
كِتَابٌ	كُتُبٌ	Books
وَلَدٌ	أَوْلَادٌ	Boys

Practice: If Muhandis (مُهَنْدِس) means "Engineer," how would you say "two engineers"?
Answer: مُهَنْدِسَانِ (Muhandisāni).
