Lesson
1. The Passive Verb
فَصْلُ فِعْلِ مَا لَمْ يُسَمَّ فَاعِلُهُ
Translation: The verb whose agent is not mentioned.
We study passive verb formation, the unmentioned agent and the nominative substitute (nāʾib al-fāʿil).
2. Source Definition
هُوَ فِعْلٌ حُذِفَ فَاعِلُهُ وَأُقِيمَ الْمَفْعُولُ مَقَامَهُ
Translation: It is a verb whose agent is omitted and whose object takes its place.
Futiḥa al-bābu: The door was opened. The doer is unmentioned; “the door” is the substitute subject.
3. Active versus Passive
فَتَحَ خَالِدٌ الْبَابَ ← فُتِحَ الْبَابُ
Active: Khālid opened the door; Khālid is the subject and al-bāba the object. Passive: Futiḥa al-bābu; the subject is unmentioned, and the former object becomes nominative.
4. Passive Does Not Mean Unknown Agent
Passive voice does not prove the agent is unknown. The speaker may know who acted but deliberately leaves that agent unmentioned.
5. Understanding Nāʾib al-Fāʿil
كَتَبَ الطَّالِبُ الدَّرْسَ ← كُتِبَ الدَّرْسُ
Al-darsa changes from accusative object to nominative nāʾib al-fāʿil; identify its grammatical position, not merely its physical role.
6. Scope of the Author’s Basic Rule
The textbook starts from transitive verbs, which take direct objects. Active kataba Zaydun risālatan becomes passive kutibat risālatun.
7. Transitive versus Intransitive
Fataḥa has a direct object; jalasa does not. The author’s straightforward passive conversion starts from a transitive construction.
8. A Nuance about Intransitives
Basic textbook conversion raises a direct object. In broader syntax, some intransitives also appear in impersonal passive constructions with suitable adjuncts; that advanced rule is not the lesson focus.
9. Parsing a Basic Passive Sentence
فُتِحَ الْبَابُ
Futiḥa is a passive past verb built on fatḥa. Al-bābu is nominative nāʾib al-fāʿil with ḍamma; no separate hidden active agent is parsed.
10. Substitute Subject versus Hidden Agent
A passive can have an overt or an understood proxy subject. Do not insert an active subject into the grammatical parsing.
11. The Core Past-Passive Pattern
فَعَلَ ← فُعِلَ
A regular triliteral past passive usually has ḍamma on the first consonant and kasra before the final consonant: fataḥa→futiḥa; kataba→kutiba.
12. Active and Passive: Ḍaraba
ضَرَبَ ← ضُرِبَ
Ḍaraba is active; ḍuriba is passive. Both are past verbs but their internal vowels encode a different voice.
13. Object Raised to Proxy Subject
قَرَأَتْ هِنْدٌ الْقِصَّةَ ← قُرِئَتِ الْقِصَّةُ
The former object becomes nominative. The feminine passive verb is qur iʾat; the linking kasra on tāʾ before al- is phonetic, not a new case ending.
14. Passive of the Quadriliteral
دَحْرَجَ ← دُحْرِجَ
The regular quadriliteral past passive uses initial ḍamma and penultimate kasra: daḥraja→duḥrija.
15. Form IV Past Passive
أَكْرَمَ ← أُكْرِمَ
Form IV retains hamzat al-qaṭʿ, now with ḍamma: akrama→ukrima. The object moves to nominative.
16. Past Passive: Group One
ضُرِبَ — دُحْرِجَ — أُكْرِمَ
The author groups forms without an initial extra tāʾ or hamzat al-waṣl: ḍuriba, duḥrija and ukrima.
17. Forms Beginning with an Extra Tāʾ
تَعَلَّمَ ← تُعُلِّمَ
In Form V, with an extra initial tāʾ, both the first and second letters take ḍamma, while the penultimate stem vowel becomes kasra: taʿallama→tuʿullima.
18. Form VI Past Passive
تَقَابَلَ ← تُقُوبِلَ
Form VI can be represented morphologically as taqābala→tuqūbila; whether a particular lexeme naturally forms a personal passive depends on its transitivity.
19. Why Two Initial Ḍammas?
The extra tāʾ is retained. The two ḍammas belong to the passive vowel pattern; they do not indicate a new root.
20. Passive of Waṣl-Hamza Forms
اِسْتَخْرَجَ ← اُسْتُخْرِجَ
Form X past passive: istakhraja→ustukhrija. The first pronounced vowel and third letter are ḍamma, with penultimate kasra.
21. Pronunciation of Hamzat al-Waṣl
اُسْتُخْرِجَ — وَاسْتُخْرِجَ
At the start, hamzat al-waṣl is pronounced with ḍamma; in connected reading its onset drops, while the stem tāʾ retains its ḍamma.
22. Form VIII Past Passive
اِخْتَبَرَ ← اُخْتُبِرَ
This is a transitive Form VIII verb: ikhtabara becomes ukhtubira; in ukhtubira al-ṭālibu the student is nominative proxy subject.
23. Three Past-Passive Families
Family 1: first ḍamma/penultimate kasra. Family 2: first two ḍammas. Family 3: first and third ḍammas. All use a penultimate kasra in the regular past patterns.
24. Worked Pattern Contrast
كُتِبَ — تُعُلِّمَ — اُسْتُخْرِجَ
Compare the exact location of ḍammas in the three past-passive formation families.
25. Imperfect Passive: General Pattern
يَفْعَلُ ← يُفْعَلُ
The normal imperfect passive begins with ḍamma on the imperfect prefix and a fatḥa before the last consonant: yaktubu→yuktabu.
26. Present-Tense Voice Contrast
يَكْتُبُ الطَّالِبُ الدَّرْسَ ← يُكْتَبُ الدَّرْسُ
The imperfect passive yuktabu marks passive voice internally. Al-darsu is a nominative proxy subject.
27. Voice versus Mood
Voice (passive) and mood (indicative/subjunctive/jussive) are independent: yuktabu is passive indicative; lan yuktaba is passive subjunctive.
28. Passive under a Jussive Particle
لَمْ يُكْتَبْ الدَّرْسُ
Lam governs the passive imperfect and makes it jussive; voice remains passive while its mood changes.
29. Form IV: Voice Marked Internally
يُكْرِمُ ← يُكْرَمُ
Both Form IV imperfect forms start with yu-. Compare the penultimate vowels: yukrimu active, yukramu passive.
30. Form II: Imperfect Passive
يُعَلِّمُ ← يُعَلَّمُ
Form II: yuʿallimu is active; yuʿallamu is passive. The vowel of the doubled consonant differentiates the two.
31. Form III: Imperfect Passive
يُحَاسِبُ ← يُحَاسَبُ
Form III: yuḥāsibu (active) changes to yuḥāsabu (passive), and the former object becomes nominative.
32. Quadriliteral: Imperfect Passive
يُدَحْرِجُ ← يُدَحْرَجُ
Quadriliteral imperfect has yu- in both voices. Its penultimate vowel is kasra in active and fatḥa in passive.
33. The Author’s Important Exception
In Forms III, IV, II and the quadriliteral, yu- occurs in both voices. Consequently the penultimate kasra/fatḥa contrast is the diagnostic.
34. What the Exception Does Not Mean
The exception does not remove the ḍamma from passive forms. It means that initial ḍamma alone does not differentiate active from passive in these forms.
35. Form X Imperfect Passive
يَسْتَخْرِجُ ← يُسْتَخْرَجُ
Form X changes both the initial imperfect-prefix vowel and penultimate vowel: yastakhriju→yustakhraju.
36. Four Imperfect Voice Pairs
Four pairs: yaftaḥu/yuftaḥu, yukrimu/yukramu, yuʿallimu/yuʿallamu, yastakhriju/yustakhraju. In each pair active precedes passive.
37. Parsing an Imperfect Passive
يُفْتَحُ الْبَابُ
The prefix ḍamma contributes to passive voice; final ḍamma marks indicative mood. Al-bābu is nominative proxy subject.
38. Hollow Verbs Need Special Treatment
A hollow verb has wāw or yāʾ as its middle root letter, e.g., q-w-l and b-y-ʿ. Its passive requires weak-letter adjustments.
39. Passive of Qāla
قَالَ ← قِيلَ
The normal hollow past passive is qīla, with the weak radical altered; qīla al-ḥaqqu means “the truth was stated.”
40. Passive of Bāʿa
بَاعَ ← بِيعَ
Bāʿa becomes bīʿa in the ordinary hollow passive. Al-kitābu is the nominative proxy subject.
41. Traditional Alternative Hollow Readings
The author records three traditional realizations: standard qīla/bīʿa; ishmām (a mixed phonetic quality); and less common wāw forms qūla/būʿa. Teach the standard form first.
42. Ishmām Is Mainly Phonetic
In this traditional context ishmām describes a modified vowel articulation. It is not necessarily represented by a separate unambiguous written spelling.
43. Hollow Augmented Patterns
The author extends the hollow-verb discussion to augmented forms corresponding to ukhtīra and unqīda, with details treated in morphology.
44. Why Some Similar Forms Differ
The author excludes uqīma and ustukhīra from the full analogy with the preceding hollow forms. Detailed causation belongs to morphology.
45. Hollow Imperfect Passive
يَقُولُ ← يُقَالُ
Yaqūlu becomes yuqālu in the imperfect passive. The middle weak radical appears as alif.
46. Hollow Imperfect of Bāʿa
يَبِيعُ ← يُبَاعُ
Yabīʿu becomes yubāʿu; the object of the active becomes nominative proxy subject in the passive.
47. Hollow Tenses Side by Side
قَالَ / قِيلَ — يَقُولُ / يُقَالُ
Hollow passive formation differs by tense: qāla/qīla in the past, yaqūlu/yuqālu in the imperfect.
48. Feminine Proxy Subject
فُتِحَتْ نَافِذَةٌ
Futiḥat nāfidhatun: feminine passive verb agrees with the following feminine proxy subject.
49. Dual Proxy Subject
فُتِحَ الْبَابَانِ
The postverbal dual proxy subject uses alif for the nominative. The preceding finite verb normally stays singular.
50. Plural Proxy Subject
كُتِبَتِ الرَّسَائِلُ
Non-human broken plural often takes feminine-singular agreement. The joining kasra on tāʾ is phonetic, not an inflectional sign.
51. Topic versus Postverbal Proxy Subject
الْبَابُ فُتِحَ
Al-bābu is a fronted topic, not a postverbal nāʾib al-fāʿil. The passive verb contains an understood proxy-subject pronoun referring back to al-bāb.
52. Why Is It Nominative?
Both the agent of an active and the proxy subject of a passive are nominative. Voice determines which grammatical label applies.
53. Conversion Must Change Both Parts
Correct conversion changes the verb’s voice and raises the former object. Leaving bāban accusative in this one-object passive is incorrect.
54. Proxy-Subject Case Signs
Nāʾib al-fāʿil is nominative, but its sign varies by noun class: ḍamma, dual alif, sound-masculine plural wāw and sound-feminine plural ḍamma.
55. Recognize Passive Past Quickly
A consolidated diagnostic of the six morphological patterns and irregular hollow forms.
56. Recognize Passive Imperfect Quickly
A consolidated recognition list across the principal imperfect passive families.
57. Passive with Negation and Jussive
لَمْ يُفْتَحِ الْبَابُ
Lam makes the passive imperfect jussive. The connected kasra before al- is phonetic; the verb remains jussive.
58. Transform Three Active Sentences
Three active-to-passive conversions. Note the feminine imperfect of risālah in pair 2, the raised objects, and the omission of each agent.
59. Chapter Summary
Core takeaways: agent omitted, former object promoted, past passive vowel families, imperfect voice independent of mood, and hollow verb exceptions.
