Lesson

1. Chapter: Definition of Plural

فَصْلٌ: الْمَجْمُوعُ
Translation: Chapter on plural nouns.
A plural denotes more than two members through a change in the singular’s form, overt or understood.
For example: rajulun → rijālun (man → men). This chapter covers forms, conditions and patterns.

2. From Dual to Plural

رَجُلٌ — رَجُلَانِ — رِجَالٌ
One man, two men, men (three or more).
Arabic uses a separate dual form for two, so an ordinary plural is not simply a dual with a different ending.

3. Visible and Understood Change

رَجُلٌ ← رِجَالٌ
A change is overt when the singular and plural look or sound different, as in rajulun → rijālun.

4. Change Not Visible on the Surface

فُلْكٌ
Fulk can refer to a vessel or vessels according to context.
The source treats its singular/plural distinction as estimated rather than visibly marked. Do not mechanically invent a new pronounced plural.

5. The Subtle Fulk Example

فُلْكٌ — قُفْلٌ — أُسْدٌ
The book contrasts the singular’s pattern (like qufl) and the plural’s understood pattern (like usd), even though the surface form fulk is shared. This is a specialized morphological point.

6. Why Qawm Is Not a Regular Plural

قَوْمٌ — رِجَالٌ
Qawm denotes a group, but in the source it is not a morphological plural built from its own singular. Rijāl, by contrast, has the singular rajul. Collective meaning alone does not prove plural formation.

7. The Two Main Plural Types

الْجَمْعُ الْمُصَحَّحُ — جَمْعُ التَّكْسِيرِ
Plurals divide into sound plurals (singular stem preserved) and broken plurals (stem pattern changed). Sound plurals are subdivided into masculine and feminine.

8. Recognizing the Sound Masculine Plural

مُسْلِمٌ ← مُسْلِمُونَ / مُسْلِمِينَ
Muslimun becomes muslimūna in the nominative and muslimīna in accusative/genitive. The lexical stem remains recognizable.

9. Nominative Plural Ending

جَاءَ الْمُسْلِمُونَ.
The Muslims came. Al-muslimūna is a nominative subject; wāw marks nominative, with ḍamma before wāw and fatḥa on nūn.

10. Accusative Plural Ending

رَأَيْتُ الْمُسْلِمِينَ.
I saw the Muslims. Al-muslimīna is the accusative object; yāʾ marks accusative, while nūn has fatḥa.

11. Genitive Plural Ending

مَرَرْتُ بِالْمُسْلِمِينَ.
I passed by the Muslims. Bi causes genitive, though the plural ending looks the same as in the accusative.

12. Do Not Confuse Dual and Plural

مُسْلِمَيْنِ — مُسْلِمِينَ
Muslimayni is dual: fatḥa before yāʾ, kasra on nūn. Muslimīna is plural: kasra before yāʾ, fatḥa on nūn. The letters alone are not enough.

13. Pluralizing a Manqūṣ Noun

قَاضٍ ← قَاضُونَ / قَاضِينَ
A manqūṣ noun such as qāḍin loses its underlying final yāʾ on taking these plural endings: qāḍūna / qāḍīna.

14. Another Manqūṣ Example

دَاعٍ ← دَاعُونَ / دَاعِينَ
Dāʿin behaves like qāḍin: dāʿūna in nominative, dāʿīna in accusative/genitive.

15. Pluralizing a Maqṣūr Noun

مُصْطَفَىٰ ← مُصْطَفَوْنَ / مُصْطَفَيْنَ
A maqṣūr name such as Muṣṭafā drops final alif before the plural ending, leaving the preceding fatḥa: muṣṭafawna / muṣṭafayna. The example refers to multiple people sharing the name.

16. Comparing Weak-Ending Nouns

قَاضُونَ — مُصْطَفَوْنَ
Qāḍūna removes manqūṣ yāʾ and has ḍamma before wāw; muṣṭafawna removes maqṣūr alif and retains fatḥa before wāw.

17. Conditions for Nouns

مُحَمَّدٌ — زَيْدٌ
For a proper noun to take this sound plural regularly, it is generally a masculine personal name referring to rational beings. Multiple bearers of a name can be counted; adjectives follow different restrictions.

18. Conditions for Adjectives

مُجْتَهِدٌ ← مُجْتَهِدُونَ
A qualifying adjective such as mujtahid can form mujtahidūna for rational masculine referents. Some adjective patterns are excluded from ordinary analogical formation.

19. Excluded Pattern: Afʿal/Faʿlāʾ

أَحْمَرُ — حَمْرَاءُ
Afʿal adjectives with faʿlāʾ feminines, such as aḥmar / ḥamrāʾ, are excluded from the regular sound masculine plural rule. Their established broken plural includes ḥumr.

20. Excluded Pattern: Faʿlān/Faʿlā

سَكْرَانُ — سَكْرَىٰ
Sakrān has feminine sakrā and falls outside the ordinary sound masculine plural adjective pattern; sakārā is its familiar broken plural.

21. Excluded Faʿīl with Passive Meaning

جَرِيحٌ = مَجْرُوحٌ
Jarīḥ on the faʿīl pattern means “wounded” (passive). This pattern and sense is excluded by the source; not every faʿīl adjective is excluded just because of the spelling.

22. Excluded Faʿūl with Active Meaning

صَبُورٌ = صَابِرٌ
Ṣabūr means “very patient” (active sense), on faʿūl. The source excludes this adjective class from ordinary sound masculine plural formation.

23. Exceptional -ūna Plurals

سِنُونَ — أَرَضُونَ — ثُبُونَ — قُلُونَ
These four traditionally attested words take wāw/nūn-like endings despite failing ordinary conditions. They are exceptional and cannot justify unrestricted -ūna formation.

24. Regular Rule versus Attested Exception

سِنُونَ — مُسْلِمُونَ
Muslimūna is a regular sound masculine plural. Sinūna is an exceptional attested form; identical-looking endings do not establish identical derivation.

25. Nūn Drops in Iḍāfah

جَاءَ مُسْلِمُو مِصْرَ.
The Muslims of Egypt arrived. Nūn disappears from a sound masculine plural when it is muḍāf. Miṣr is treated here as diptote (genitive marked with fatḥa); triptote usage is also attested.

26. Accusative Plural in Iḍāfah

رَأَيْتُ مُعَلِّمِي الْمَدْرَسَةِ.
I saw the school’s teachers. Muʿallimī is accusative by yāʾ and loses nūn because of iḍāfah; al-madrasati is genitive.

27. The Sound Feminine Plural

مُسْلِمَةٌ ← مُسْلِمَاتٌ
Muslimatun → muslimātun. In the regular sound feminine plural, the core stem remains and the word takes the -āt ending.

28. Feminine Plural Nominative

جَاءَتْ مُسْلِمَاتٌ.
Muslimātun is a nominative feminine sound plural with ḍamma, not the masculine-plural wāw.

29. Feminine Plural Accusative Is Kasrah

رَأَيْتُ مُسْلِمَاتٍ.
Muslimātin is accusative even though its ending is kasrah; sound feminine plurals use kasrah in place of fatḥa in the accusative.

30. Feminine Plural Genitive

مَرَرْتُ بِمُسْلِمَاتٍ.
Muslimātin is genitive after bi-. Both accusative and genitive are expressed with kasrah, but the syntax differs.

31. Plural of Female Proper Names

هِنْدٌ ← هِنْدَاتٌ
Hind (as a female personal name) can take the -āt sound plural when multiple women share the name. A feminine tāʾ in the singular is not an absolute prerequisite.

32. Extra Restrictions for Feminine Adjectives

مُسْلِمَةٌ — مُسْلِمَاتٌ
For feminine adjectives, the source imposes extra analogical conditions. Muslimatun → muslimātun fits the pattern, with a corresponding masculine adjective that forms muslimūna.

33. Adjectives Without Feminine Tāʾ

حَائِضٌ — حَامِلٌ
Ḥāʾiḍ and ḥāmil describe women without final feminine tāʾ. The book notes a restriction on deriving -āt forms by its regular analogy; this is not a claim about every attested usage.

34. Side-by-Side Case Markers

Masculine sound plural: nominative wāw; accusative/genitive yāʾ.
Feminine sound plural: nominative ḍamma; accusative/genitive kasrah.
Remember case and sign separately.

35. Recognizing Broken Plurals

رَجُلٌ ← رِجَالٌ
Broken plurals change the singular pattern. Rajul → rijāl and kitāb → kutub illustrate two different broken patterns.

36. Declension of Broken Plurals

جَاءَ رِجَالٌ — رَأَيْتُ رِجَالًا — مَرَرْتُ بِرِجَالٍ
Rijālun, rijālan, rijālin show ordinary triptote declension of a broken plural. Some other broken-plural patterns are diptote, so do not overgeneralize.

37. Broken Plurals of Triliteral Nouns

رِجْلٌ ← أَرْجُلٌ
ضِرْسٌ ← أَضْرَاسٌ
قَلْبٌ ← قُلُوبٌ
Three-letter singulars can take various broken plural patterns: arjul, aḍrās, qulūb. Their formation is often learned through attested usage, not one universal template.

38. Broken Plurals of Four-Letter Nouns

جَعْفَرٌ ← جَعَافِرُ
جَدْوَلٌ ← جَدَاوِلُ
Jaʿfar → jaʿāfir, jadwal → jadāwil illustrate the faʿālil pattern for four-consonant bases. These plurals are diptote as ṣīghat muntahā al-jumūʿ.

39. Plurals of Small and Large Number

جَمْعُ الْقِلَّةِ — جَمْعُ الْكَثْرَةِ
Traditionally, paucity plurals principally indicate 3–10 and abundance plurals more than ten. Usage can extend beyond these base ranges; patterns alone do not determine the actual count in every sentence.

40. The Four Paucity Patterns

أَفْعُلٌ — أَفْعَالٌ — فِعْلَةٌ — أَفْعِلَةٌ
The source gives four central broken-plural patterns of paucity: afʿul, afʿāl, fiʿlah and afʿilah. The next slides show all four with examples.

41. First Two Paucity Patterns

فَلْسٌ ← أَفْلُسٌ
ضِرْسٌ ← أَضْرَاسٌ
Aflus follows afʿul; aḍrās follows afʿāl. Identify a pattern from its complete vowel-and-letter structure.

42. The Other Two Paucity Patterns

فَتًى ← فِتْيَةٌ
رَغِيفٌ ← أَرْغِفَةٌ
Fityah exemplifies fiʿlah, and arghifah exemplifies afʿilah. Together with the previous slide, these cover all four paucity templates.

43. Sound Plurals and the Paucity Classification

زَيْدُونَ — مُسْلِمَاتٌ
The commentary also includes sound masculine and feminine plurals without al- in the paucity classification, alongside the four broken-plural patterns. This is a classification of usage, not an absolute headcount rule.

44. Patterns of Plural Abundance

قُلُوبٌ — رِجَالٌ — جَعَافِرُ
Abundance plurals have many patterns, including qulūb, rijāl and jaʿāfir. These are examples rather than an exhaustive list.

45. Base Meaning versus Actual Usage

ثَلَاثَةَ قُرُوءٍ
The Qurʾānic phrase (2:228) uses qurūʾ with the numeral three even though it is treated as an abundance pattern. Pattern and actual quantity need not always coincide. This lesson does not adjudicate its legal interpretation.

46. Compare All Three Main Forms

مُسْلِمُونَ — مُسْلِمَاتٌ — رِجَالٌ
Muslimūna is a sound masculine plural, muslimātun a sound feminine plural, and rijālun a broken plural. Case markers depend on the category.

47. Integrated Parsing Exercise

جَاءَ الْمُعَلِّمُونَ وَالْمُعَلِّمَاتُ.
The teachers (male and female) arrived. Al-muʿallimūna is nominative by wāw; al-muʿallimātu is a coordinated nominative by ḍamma. The preceding verb is singular in verb–subject order.

48. Genitive Across Plural Types

سَلَّمْتُ عَلَى مُعَلِّمِينَ وَمُعَلِّمَاتٍ وَرِجَالٍ.
All three are genitive after ʿalā (directly or by coordination). The masculine sound plural has yāʾ, while the feminine sound and triptote broken plural have kasrah.

49. Four Frequent Errors

Common corrections: accusative muslimīna; feminine accusative muslimātin; iḍāfah loses the masculine plural nūn; fulk can have singular or plural reference.

50. Key Takeaways and Next Chapter
