Lesson
1. Four Patterns of Imperfect Mood Marking
فَصْلٌ فِي أَصْنَافِ إِعْرَابِ الْفِعْلِ
Translation: A chapter on patterns of verb inflection. The preceding lesson introduced the three imperfect moods; this chapter distinguishes how their marks appear on different forms.
2. Three Moods, Four Patterns
There are only three moods: nominative/indicative, subjunctive, and jussive. The four categories describe their differing visible or estimated markers.
3. Identify the Governor First
يَكْتُبُ — لَنْ يَكْتُبَ — لَمْ يَكْتُبْ
Yaktubu is indicative, lan yaktuba is subjunctive, and lam yaktub is jussive. First determine the governor, then the form-specific ending.
4. Preview of the Four Categories
Pattern 1: visible vowels. Pattern 2: nūn retained or omitted. Pattern 3: weak-final yāʾ/wāw, estimated ḍamma, visible fatḥa, dropping the final letter for jazm. Pattern 4: final alif, both vowels estimated, letter dropped for jazm.
5. Category 1: Singular Sound-Final Imperfect
يَكْتُبُ — لَنْ يَكْتُبَ — لَمْ يَكْتُبْ
For a singular sound-final imperfect other than the feminine singular addressee form, indicative is marked by ḍamma, subjunctive by fatḥa and jussive by sukūn.
6. Category 1: Indicative
الطَّالِبُ يَكْتُبُ.
The student writes. Yaktubu is indicative with a visible ḍamma on its final bāʾ.
7. Category 1: Subjunctive
لَنْ يَكْتُبَ الطَّالِبُ.
The student will not write. Lan governs yaktuba as subjunctive; the ending fatḥa is visible.
8. Category 1: Jussive
لَمْ يَكْتُبْ الطَّالِبُ.
The student did not write. Lam makes yaktub jussive with a final sukūn; the sound final consonant remains.
9. What Sound-Final Means
يَقُولُ — لَنْ يَقُولَ — لَمْ يَقُلْ
Sound-final concerns the final radical, not whether the entire root lacks weak letters. Yaqūlu has an internal weak vowel but final lām is sound. In lam yaqul, internal shortening is morphological, while final sukūn marks jazm.
10. Masculine and Feminine Singular Address
أَنْتَ تَكْتُبُ — أَنْتِ تَكْتُبِينَ
Anta taktubu is second-person masculine singular (category 1); anti taktubīna is second-person feminine singular (category 2). Initial tāʾ alone is not enough.
11. Third-Person Feminine Singular
هِيَ تَكْتُبُ — لَنْ تَكْتُبَ — لَمْ تَكْتُبْ
The third-person feminine singular also takes visible vowel mood endings, unlike second-person feminine singular in the five verb forms.
12. Quick Parsing of Category 1
يَفْهَمُ — لَنْ يَفْهَمَ — لَمْ يَفْهَمْ
Yafhamu / yafhama / yafham: final ḍamma, fatḥa, then sukūn. No final consonant is removed.
13. Category 2: Nūn as the Mood Marker
يَكْتُبُونَ — لَنْ يَكْتُبُوا — لَمْ يَكْتُبُوا
Category 2 is raised by the retention of nūn and made subjunctive/jussive by dropping nūn. The subject ending itself is retained.
14. The Five Surface Patterns
يَفْعَلَانِ — تَفْعَلَانِ — يَفْعَلُونَ — تَفْعَلُونَ — تَفْعَلِينَ
The five imperfect patterns comprise two dual forms, two masculine plural forms, and one second-person feminine singular form. Tafaʿlāni serves either gender in second-person dual address.
15. Dual Third Person: Three Moods
هُمَا يَكْتُبَانِ — لَنْ يَكْتُبَا — لَمْ يَكْتُبَا
The third-person dual retains nūn in the indicative and drops it in both subjunctive and jussive. The dual alif remains.
16. Dual Second Person: Three Moods
أَنْتُمَا تَكْتُبَانِ — لَنْ تَكْتُبَا — لَمْ تَكْتُبَا
The second-person dual follows the same nūn-retention/deletion pattern; its alif does not disappear.
17. Masculine Plural Third Person
هُمْ يَكْتُبُونَ — لَنْ يَكْتُبُوا — لَمْ يَكْتُبُوا
Yaktubūna has nūn in the indicative. Yaktubū is both subjunctive and jussive on the surface, depending on lan/lam. Wāw al-jamāʿah remains the subject pronoun.
18. Masculine Plural Second Person
أَنْتُمْ تَكْتُبُونَ — لَنْ تَكْتُبُوا — لَمْ تَكْتُبُوا
Antum taktubūna changes by retaining nūn in the indicative and omitting it in subjunctive and jussive.
19. Second-Person Feminine Singular
أَنْتِ تَكْتُبِينَ — لَنْ تَكْتُبِي — لَمْ تَكْتُبِي
Anti taktubīna is category 2, despite addressing only one person. Its nūn disappears in subjunctive/jussive while yāʾ al-mukhāṭabah remains.
20. Silent Alif After Plural Wāw
لَنْ يَكْتُبُوا — لَمْ يَكْتُبُوا
The silent distinguishing alif is written after plural wāw. It is not a subject pronoun or the sign of mood; deletion of nūn is the mood marker.
21. Inflectional Nūn vs Feminine Plural Nūn
يَكْتُبُونَ — هُنَّ يَكْتُبْنَ
In yaktubūna, final nūn marks indicative and is omitted in other moods. In yaktubna, nūn al-niswah is the subject pronoun and the verb is built on sukūn.
22. Emphatic Nūn Is Different
لَيَكْتُبَنَّ
Nūn al-tawkīd intensifies a verb and is not the indicative nūn of the five verbs. Direct emphatic-nūn attachment is a separate building rule.
23. Parsing a Five-Verb Form
لَمْ يَكْتُبُوا الدَّرْسَ.
Lam is jussive; yaktubū is jussive by dropping nūn; plural wāw is the subject; ad-darsa is the accusative direct object.
24. Category 3: Yāʾ- and Wāw-Final
يَرْمِي — يَدْعُو
For yāʾ/wāw-final imperfects outside the five verb forms: indicative has estimated ḍamma, subjunctive a visible fatḥa, and jussive deletes the final weak letter.
25. Yāʾ-Final: Indicative
هُوَ يَرْمِي الْكُرَةَ.
He throws the ball. Yarmī is indicative with an estimated ḍamma on final yāʾ, suppressed because pronouncing it is heavy.
26. Yāʾ-Final: Subjunctive
لَنْ يَرْمِيَ الْكُرَةَ.
Lan yarmiya is subjunctive with a visible fatḥa on final yāʾ, not an estimated one.
27. Yāʾ-Final: Jussive
لَمْ يَرْمِ الْكُرَةَ.
Lam yarmi is jussive by dropping the final yāʾ. The kasra on mīm remains but is not itself the jussive marker.
28. Wāw-Final: Indicative
هُوَ يَدْعُو.
Yadʿū is indicative with ḍamma estimated on the final wāw, not marked by the visible ḍamma on ʿayn.
29. Wāw-Final: Subjunctive
لَنْ يَدْعُوَ.
Lan yadʿuwa is subjunctive; fatḥa is visible on final wāw, which stays in the word.
30. Wāw-Final: Jussive
لَمْ يَدْعُ.
Lam yadʿu is jussive by dropping the final wāw; the ḍamma on ʿayn is the surviving stem vowel, not the mood marker.
31. Side-by-Side Comparison
For both yarmī and yadʿū, indicative ḍamma is estimated, subjunctive fatḥa is visible, and the jussive deletes the final weak letter.
32. Avoid Overgeneralizing Weak Verbs
يَقُولُ — يَدْعُو
Yaqūlu is sound-final (category 1), because its final radical is lām. Yadʿū is wāw-final (category 3). The location of the weak radical matters.
33. Category 4: Alif-Final Imperfect
يَسْعَى — لَنْ يَسْعَى — لَمْ يَسْعَ
Alif-final imperfects outside the five verb forms have both indicative ḍamma and subjunctive fatḥa estimated; the jussive deletes final alif.
34. Alif-Final: Indicative
هُوَ يَسْعَى فِي الْخَيْرِ.
Yasʿā is indicative with an estimated ḍamma on the final alif, which cannot show the vowel.
35. Alif-Final: Subjunctive
لَنْ يَسْعَى فِي الشَّرِّ.
Lan yasʿā is subjunctive with an estimated fatḥa; its surface spelling matches the indicative.
36. Alif-Final: Jussive
لَمْ يَسْعَ فِي الشَّرِّ.
Lam yasʿa is jussive by deleting final alif. The remaining fatḥa on ʿayn is not a subjunctive marker.
37. More Alif-Final Examples
يَخْشَى — لَنْ يَخْشَى — لَمْ يَخْشَ
Yakhshā has estimated endings in both indicative and subjunctive and loses final alif after lam.
38. Why Final Alif Is Special
A final yāʾ or wāw can carry a visible subjunctive fatḥa, unlike final alif which cannot carry a vowel.
39. Five-Verb Endings Take Priority
يَرْمِي — يَرْمِيَانِ — لَنْ يَرْمِيَا
Yarmī singular follows category 3. Dual yarmiyāni and lan yarmiyā follow category 2 through nūn retention/deletion despite the weak root.
40. Weak-Root Masculine Plural
يَدْعُونَ — لَنْ يَدْعُوا — لَمْ يَدْعُوا
In yadʿūna/lan yadʿū/lam yadʿū (with silent distinguishing alif in written plural forms), the five-verb nūn rule governs, unlike singular yadʿū/lam yadʿu. The plural wāw stays.
41. Complete Four-Pattern Summary
One-line summary: sound-final visible vowel changes; five verbs retain/delete nūn; yāʾ/wāw-final verbs have estimated ḍamma and visible fatḥa; alif-final verbs have both vowels estimated. Weak final letters drop in the jussive.
42. What If the Spelling Does Not Change?
يَسْعَى — لَنْ يَسْعَى
Yasʿā looks identical in indicative and subjunctive, but the estimated mood vowel differs because of the governor.
43. Do Not Misread Residual Vowels
لَمْ يَرْمِ — لَمْ يَدْعُ — لَمْ يَسْعَ
Residual kasra, ḍamma and fatḥa before a deleted weak letter are not mood markers. All three jussives are identified by deletion of the final weak radical.
44. Name Both Governor and Mood Marker
لَمْ يَرْمِ الطَّالِبُ الْكُرَةَ.
Lam is governor, yarmi is jussive by deleting yāʾ, aṭ-ṭālibu is subject and al-kurata is object.
45. Parse a Dual Example
لَنْ يَكْتُبَا الدَّرْسَ.
Lan is subjunctive; yaktubā has deleted nūn; dual alif is the subject pronoun and ad-darsa is the direct object.
46. Three Quick Practice Questions
Worked practice: lan yarmiya has visible fatḥa; lam yasʿa loses final alif; lam yaktubū loses inflectional nūn.
47. Lesson Recap and Next Step
The governor determines mood; verb shape determines how that mood is expressed. The next chapter treats the indicative and its governing condition.
