What Does “Forbidden of Declension” Mean in Arabic?
In Arabic, most nouns are fully declinable, which means they can take the full range of case endings (nominative, accusative, and genitive) and can accept the tanween (nunation, indicated by a double vowel sign). However, certain nouns are classified as “forbidden of declension” (الممنوع من الصرف), which means they do not take tanween and have restricted case endings. Understanding which nouns fall under this rule and why is crucial for learners aiming for grammatical accuracy.
The Main Rules Governing Forbidden of Declension Nouns
There are specific rules that determine which nouns are classified as forbidden of declension. These typically relate to the noun’s structure, meaning, or both. Here are the main categories:
1. Nouns with Certain Patterns or Endings
- Adjectives ending in “اء” (alif followed by hamza): For example, حمراء (red, feminine), صفراء (yellow, feminine).
- Nouns ending in “ان” (alif and nun): Such as عثمان (Othman), رحمن (Rahman).
2. Nouns Denoting Proper Names
- Non-Arabic names: Names not originally Arabic, such as إبراهيم (Ibrahim), إسماعيل (Ismail).
- Female names ending in “اء”: Like صحراء (Sahara), سناء (Sana).
3. Nouns on Certain Patterns
- Adjectives on the pattern “أفعل” and its feminine “فعلاء”: For example, أحمر (red, masculine), حمراء (red, feminine).
- Nouns on the pattern “مفعل”: Such as مسجد (mosque) are not forbidden, but exceptions exist in other patterns.
4. Nouns with Combined Reasons
- Nouns that are both feminine and on the pattern of “فعلاء”: Like حمراء (red, feminine).
- Nouns that are proper names and non-Arabic: Like إسماعيل (Ismail).
How Do Forbidden of Declension Nouns Behave?
Unlike regular nouns, forbidden of declension nouns:
- Do not take tanween (the double vowel sign at the end of a noun)
- Take a single vowel case ending only in nominative and accusative positions
- In the genitive case, they take a fatha (ـَ) instead of a kasra (ـِ), unless preceded by the definite article “ال”
Example:
- Nominative: جاءَ عثمانُ (Othman came)
- Accusative: رأيتُ عثمانَ (I saw Othman)
- Genitive: مررتُ بعثمانَ (I passed by Othman)
Note that there is no tanween and the genitive case uses fatha instead of the usual kasra.
When Are Forbidden of Declension Nouns Treated Normally?
If a forbidden of declension noun is made definite by the article “ال”, it will behave like a regular noun and take the normal case endings, including kasra in the genitive.
Example: مررتُ بالعثمانِ (I passed by the Othman – now definite, takes kasra)
