Noun Case Classes: Type 2 — Sound Feminine Plural

1. The Second Class of Noun Case-Marking

الثَّانِي: أَنْ يَكُونَ الرَّفْعُ بِالضَّمَّةِ، وَالنَّصْبُ وَالْجَرُّ بِالْكَسْرَةِ، وَيَخْتَصُّ بِجَمْعِ الْمُؤَنَّثِ السَّالِمِ.
Translation: The second class takes ḍamma in the nominative, but kasra in both the accusative and genitive. This is specific to the sound feminine plural.

In the first class, accusative was marked by fatḥa. Here its sign is kasra. That contrast is the core rule of this lesson.

2. The Author’s Examples: مُسْلِمَات

كَـ«مُسْلِمَاتٍ»؛ تَقُولُ: «جَاءَتْنِي مُسْلِمَاتٌ، وَرَأَيْتُ مُسْلِمَاتٍ، وَمَرَرْتُ بِمُسْلِمَاتٍ».
Translation: For example, “Muslim women.” You say: “Muslim women came to me; I saw Muslim women; and I passed by Muslim women.”

The same noun serves three different syntactic roles: subject, direct object, and a noun governed by a preposition. Its case follows the role, not just the visible vowel.

3. Recognizing the Sound Feminine Plural

A plural refers to more than one person or thing; feminine concerns the feminine gender; and sound indicates that the singular word’s basic form is largely preserved.

مُسْلِمَةٌ ← مُسْلِمَاتٌ — one Muslim woman → Muslim women.
طَالِبَةٌ ← طَالِبَاتٌ — one female student → female students.
مُعَلِّمَةٌ ← مُعَلِّمَاتٌ — one female teacher → female teachers.

These are common formations. Not every word ending in «ات» is automatically a sound feminine plural; check its singular and pattern.

4. Three Cases, Two Visible Vowels

Nominative (rafʿ): مُسْلِمَاتٌ — ḍamma (here with tanwīn).
Accusative (naṣb): مُسْلِمَاتٍ — kasra (here with tanwīn).
Genitive (jarr): مُسْلِمَاتٍ — kasra (here with tanwīn).

Accusative and genitive are distinct cases even when their visible ending is identical. The governor and the sentence structure identify the case.

5. جَاءَتْنِي مُسْلِمَاتٌ: Nominative

جَاءَتْنِي مُسْلِمَاتٌ.
Translation: Muslim women came to me.

Grammatical analysis
جَاءَتْ: past-tense verb; the final تْ marks feminine gender.
نِي: ن is the protective nūn, and ي is the first-person object pronoun.
مُسْلِمَاتٌ: subject (fāʿil), so it is nominative with ḍamma.

The key point: the subject takes مُسْلِمَاتٌ, not مُسْلِمَاتٍ.

6. رَأَيْتُ مُسْلِمَاتٍ: Accusative

رَأَيْتُ مُسْلِمَاتٍ.
Translation: I saw Muslim women.

Grammatical analysis
رَأَيْتُ: past-tense verb; the final تُ is its subject pronoun.
مُسْلِمَاتٍ: direct object, hence accusative.
Accusative sign: kasra, because this is a sound feminine plural.

Although the form ends in kasra, it is accusative, not genitive, in this sentence.

7. مَرَرْتُ بِمُسْلِمَاتٍ: Genitive

مَرَرْتُ بِمُسْلِمَاتٍ.
Translation: I passed by Muslim women.

Grammatical analysis
مَرَرْتُ: past-tense verb with first-person subject pronoun.
بِـ: preposition.
مُسْلِمَاتٍ: a genitive noun with kasra as its sign.

This time مُسْلِمَاتٍ really is genitive, because the preposition governs it.

8. Why Do Accusative and Genitive Look Alike?

رَأَيْتُ مُسْلِمَاتٍ.
Translation: I saw Muslim women.
مَرَرْتُ بِمُسْلِمَاتٍ.
Translation: I passed by Muslim women.

In the first sentence, مُسْلِمَاتٍ is an accusative object; in the second it is a genitive noun following a preposition.

The case sign is the same, but the case is different. Never infer grammatical function from the ending alone.

9. Kasra as an Accusative Sign

An ordinary fully declinable sound-final singular usually takes fatḥa for the accusative: رَأَيْتُ زَيْدًا.

A sound feminine plural takes kasra instead: رَأَيْتُ مُسْلِمَاتٍ.

Accusative names the grammatical case. Fatḥa and kasra are possible signs of that case in different noun classes.

10. Comparing the First and Second Classes

First class: زَيْدٌ
Nominative: زَيْدٌ — ḍamma.
Accusative: زَيْدًا — fatḥa.
Genitive: زَيْدٍ — kasra.

Second class: مُسْلِمَاتٌ
Nominative: مُسْلِمَاتٌ — ḍamma.
Accusative: مُسْلِمَاتٍ — kasra.
Genitive: مُسْلِمَاتٍ — kasra.

Both classes use ḍamma for nominative and kasra for genitive here. The key difference is the accusative sign.

11. Case Vowels and Tanwīn

The forms مُسْلِمَاتٌ and مُسْلِمَاتٍ display double-vowel endings called tanwīn.

For this noun class, ḍamma marks the nominative and kasra marks both accusative and genitive. With tanwīn, these appear doubled.

Compare definite forms: الْمُسْلِمَاتُ (nominative), الْمُسْلِمَاتِ (accusative), الْمُسْلِمَاتِ (genitive). Tanwīn disappears, but the case rule stays the same.

12. Apply the Rule to طَالِبَات

Now apply the book’s rule to a new example. These sentences are teaching examples, not quotations from the source.

حَضَرَتْ طَالِبَاتٌ.
Translation: Female students arrived.
طَالِبَاتٌ: nominative subject, marked by ḍamma.

رَأَيْتُ طَالِبَاتٍ.
Translation: I saw female students.
طَالِبَاتٍ: accusative object, marked by kasra.

13. طَالِبَاتٍ After a Preposition

سَلَّمْتُ عَلَى طَالِبَاتٍ.
Translation: I greeted female students.

Grammatical analysis
سَلَّمْتُ: past-tense verb with first-person subject pronoun.
عَلَى: preposition.
طَالِبَاتٍ: genitive noun, with kasra.

Compare with رَأَيْتُ طَالِبَاتٍ. Both endings contain kasra, but one noun is accusative and the other genitive.

14. Not Every -āt Ending Has the Same Analysis

مُسْلِمَاتٌ and طَالِبَاتٌ are common sound feminine plurals.

But the ending «ات» alone is not proof. For example, بَيْتٌ ← أَبْيَاتٌ changes the internal plural pattern, so أَبْيَاتٌ is a broken plural.

رَأَيْتُ أَبْيَاتًا.
Translation: I saw several lines of poetry.
Here أَبْيَاتًا is accusative with fatḥa. It does not follow the sound feminine plural rule merely because the spelling ends in «ات».

15. Same Form, Different Syntactic Analysis

This is an additional teaching example, not a quotation from the book.

شَاهَدْتُ مُعَلِّمَاتٍ.
Translation: I saw female teachers.
مُعَلِّمَاتٍ: accusative direct object, marked by kasra.

تَحَدَّثْتُ إِلَى مُعَلِّمَاتٍ.
Translation: I spoke to female teachers.
إِلَى: preposition.
مُعَلِّمَاتٍ: genitive noun, marked by kasra.

The form is identical, but the syntactic function is different.

16. Guided Practice: Identify the Governor

Find the governor or syntactic relation first, then name the case.

دَخَلَتْ مُسْلِمَاتٌ. — What is the role of مُسْلِمَاتٌ?
Answer: nominative subject; ḍamma.

رَأَيْتُ مُسْلِمَاتٍ. — What is its role?
Answer: accusative direct object; kasra.

سَلَّمْتُ عَلَى مُسْلِمَاتٍ. — What is its role?
Answer: genitive after a preposition; kasra.

17. Correct These Common Mistakes

Mistake 1: Calling مُسْلِمَاتٍ in رَأَيْتُ مُسْلِمَاتٍ genitive just because it has kasra.
Correction: It is an accusative direct object, and this noun class uses kasra in the accusative.

Mistake 2: Reading مُسْلِمَاتٌ as accusative.
Correction: The ḍamma marks the nominative here.

Mistake 3: Giving every plural the same accusative vowel.
Correction: The ordinary fully declinable broken plural رِجَالًا takes fatḥa, while the sound feminine plural مُسْلِمَاتٍ takes kasra.

18. Explain the Rule Yourself

Ask yourself three questions:

1. Which sign marks the nominative of the sound feminine plural? — ḍamma.
2. Which sign marks its accusative? — kasra.
3. If accusative and genitive look alike, how can you distinguish them? — Examine the governor and syntax.

Now explain aloud the difference between رَأَيْتُ طَالِبَاتٍ and مَرَرْتُ بِطَالِبَاتٍ.
