One Two and Many
Arabic uses a three-way system for counting: Singular (1), Dual (2), and Plural (3+). Unlike English, you must use a specific 'Dual' form for exactly two things.
How It Works
In Modern Standard Arabic, nouns, adjectives, pronouns, and verbs change based on whether you are talking about one, two, or many things.
- Singular (مفرد): The base form for one person or thing.
- Dual (مثنى): Used for exactly two. It is formed by adding ـانِ (-ani) in the subject position, or ـَيْنِ (-ayni) when the word is an object or follows a preposition. For feminine words ending in ة, change it to ت before adding these endings.
- Plural (جمع): Used for three or more. This includes regular masculine, regular feminine, and broken plurals.
Important Rules:
1. Non-Human Plurals: Plural things that are not people are treated as feminine singular. See Non-human Plural Agreement.
2. Verb Agreement: Verbs match the number if they follow the subject. However, if the verb starts the sentence, it stays singular but must still match the gender of the subject (e.g., Tadhhabu al-talibat).
3. Nūn Deletion: When a dual or sound masculine plural noun is the first word in an Idafa (possession), the final ن (nūn) is dropped (e.g., Mu'allimū al-madrasa).
4. Adjectives: Must match the number of the noun. While human broken plurals usually take plural adjectives, they can occasionally take feminine singular agreement in formal contexts.
