When an Arabic transitive verb becomes passive, its active agent is suppressed and an affected argument is promoted. Traditional grammar calls this promoted argument نَائِبُ الْفَاعِلِ “the deputy of the agent.” It is nominative and controls verbal agreement, but it is not the semantic agent: in كُسِرَ الزجاجُ “the glass was broken,” the glass did not perform the breaking.
English calls the promoted phrase the passive subject. That is a useful syntactic comparison, but Arabic's term preserves an important insight: the phrase has taken over the grammatical position left by the absent active subject. The internal-passive overview explains the voice contrast; this page focuses on the promoted phrase itself.
From object to nominative نائب الفاعل
Compare the case roles in a fully inflected active–passive pair:
| Clause | Agent | Affected argument |
|---|---|---|
| رَاجَعَ الْمُدِيرُ التَّقْرِيرَ | الْمُدِيرُ nominative فاعل | التَّقْرِيرَ accusative object |
| رُوجِعَ التَّقْرِيرُ | suppressed | التَّقْرِيرُ nominative نائب الفاعل |
راجع المدير التقرير قبل الاجتماع.
rājaʿa l-mudīru t-taqrīra qabla l-ijtimāʿ.
The director reviewed the report before the meeting. (Active: التقرير is accusative.)
روجع التقرير قبل الاجتماع.
rūjiʿa t-taqrīru qabla l-ijtimāʿ.
The report was reviewed before the meeting. (Passive: التقرير is nominative.)
In ordinary unvocalized writing, التقرير looks unchanged. Case becomes audible and analytically important in the spoken form: active object at-taqrīra, passive promoted argument at-taqrīru. A learner who relies only on the consonantal spelling can miss the syntactic reorganization.
Nominative forms across number and gender
Promotion selects the nominative member of the noun's own case paradigm. A singular normally shows -u/-un when full case is pronounced. A dual uses -āni, a sound masculine plural -ūna, and a sound feminine plural -ātu.
| Promoted argument | Nominative form | Verb-first passive |
|---|---|---|
| one male researcher | الْبَاحِثُ | دُعِيَ الْبَاحِثُ |
| two male researchers | الْبَاحِثَانِ | دُعِيَ الْبَاحِثَانِ |
| male engineers | الْمُهَنْدِسُونَ | كُرِّمَ الْمُهَنْدِسُونَ |
| female engineers | الْمُهَنْدِسَاتُ | كُرِّمَتِ الْمُهَنْدِسَاتُ |
دعي الباحثان إلى تقديم ورقة مشتركة.
duʿiya l-bāḥithāni ʾilā taqdīmi waraqatin mushtaraka.
The two male researchers were invited to present a joint paper. (Dual nominative -āni.)
كرمت المهندسات في ختام المشروع.
kurrimati l-muhandisātu fī khitāmi l-mashrūʿ.
The female engineers were honored at the conclusion of the project. (Feminine-plural nominative -ātu.)
The noun ending and the verb's number agreement are separate. الباحثان is unmistakably dual and nominative, even though the preceding verb دُعي is singular. Arabic has not turned the dual noun into a singular; it uses the normal formal VSO agreement pattern.
Verb-first order: singular verb, gender preserved
In neutral formal verb-first order, an overt human dual or plural promoted argument normally follows a singular verb. Masculine referents select masculine singular; feminine referents select feminine singular.
كرم المهندسون بعد نجاح الاختبار.
kurrima l-muhandisūna baʿda najāḥi l-ikhtibār.
The male engineers were honored after the test succeeded. (Verb-first masculine singular.)
كرمت الباحثتان بجائزة دولية.
kurrimati l-bāḥithatāni bijāʾizatin dawliyya.
The two female researchers were honored with an international prize. (Verb-first feminine singular.)
This asymmetry is strongest in controlled formal MSA. It is not an optional stylistic trick to make the verb shorter; it is the ordinary agreement pattern when the finite verb precedes its overt nominal subject or نائب الفاعل.
Subject-first order: full human agreement
When a human dual or plural promoted argument comes first as the topic, the following verb normally shows full number and gender agreement.
الباحثان دعيا إلى تقديم ورقة مشتركة.
al-bāḥithāni duʿiyā ʾilā taqdīmi waraqatin mushtaraka.
The two male researchers were invited to present a joint paper. (Subject-first dual agreement.)
الباحثتان كرمتا بجائزة دولية.
al-bāḥithatāni kurrimatā bijāʾizatin dawliyya.
The two female researchers were honored with an international prize. (Subject-first feminine dual.)
المهندسون كرموا بعد نجاح الاختبار.
al-muhandisūna kurrimū baʿda najāḥi l-ikhtibār.
The male engineers were honored after the test succeeded. (Subject-first masculine plural.)
المهندسات كرمن في ختام المشروع.
al-muhandisātu kurrimna fī khitāmi l-mashrūʿ.
The female engineers were honored at the conclusion of the project. (Subject-first feminine plural.)
Verb-first order is natural when reporting that an event occurred; subject-first order makes the promoted argument the discourse topic. Both can translate the same English passive, whose fixed subject-before-verb order does not show this Arabic information-structure choice.
Nonhuman plurals take feminine singular agreement
A nonhuman plural promoted argument conventionally triggers feminine singular agreement in formal MSA, whether it follows or precedes the verb. Its noun remains plural and nominative; only the agreement is feminine singular.

Dual nouns are not treated as plurals for this rule. Subject-first الوثيقتان نُشرتا has feminine dual agreement; verb-first نُشرت الوثيقتان has the ordinary preceding feminine singular verb.
الوثيقتان نشرتا بعد رفع السرية عنهما.
al-wathīqatāni nushiratā baʿda rafʿi s-sirriyyati ʿanhumā.

Ditransitives: one argument is promoted
With a verb that takes two objects, one object becomes نائب الفاعل and the other normally remains in its original complement role. مَنَحَتِ الجامعةُ الطالبةَ منحةً “the university granted the student a scholarship” can become مُنِحَتِ الطالبةُ منحةً “the student was granted a scholarship.”
منحت الطالبة منحة كاملة لإكمال دراستها.
muniḥati ṭ-ṭālibatu minḥatan kāmilatan li-ʾikmāli dirāsatihā.
The female student was granted a full scholarship to complete her studies.
Here الطالبةُ is nominative نائب الفاعل; منحةً remains accusative. Do not promote both. Which object is promoted depends on the verb's construction and established usage, not on the English word order alone.
Aspect and mood belong to the verb, not the noun
The promoted argument remains nominative with a perfect or imperfect passive. Mood particles change the imperfect ending, not its nominative argument: يُفحصُ الطلبُ, لن يُفحصَ الطلبُ, لم يُفحصِ الطلبُ in connected speech before the article.
لن يفحص الطلب قبل دفع الرسوم.
lan yufḥaṣa ṭ-ṭalabu qabla dafʿi r-rusūm.
The application will not be examined before the fees are paid. (Passive subjunctive; الطلب remains nominative.)
Weak and geminate passive stems may look irregular—دُعِيَ الباحثُ, رُدَّ الطلبُ, لم يُقَلْ شيءٌ—but the promoted phrase still follows the same case and agreement principles. Do not “repair” دُعي to a sound-root pattern or treat رُدَّ as active merely because its shadda hides two radicals.
What نائب الفاعل is not
- It is not the hidden person who performed the action.
- It is not automatically the first noun after any passive-looking form; case, valency, and agreement must support the analysis.
- It is not an accusative direct object left unchanged after passivization.
- It is not every prepositional phrase in an agentless clause. Formal Arabic also has impersonal passives with no overt nominative noun, a construction treated separately.
The semantic role may be patient, theme, recipient, experiencer, or another argument licensed by the verb. “Deputy of the agent” names a grammatical function, not a claim that the promoted entity somehow acts.
Common Mistakes
Keeping accusative case after promotion
❌ روجع التقرير النهائي قبل الاجتماع.
rūjiʿa t-taqrīra n-nihāʾiyya qabla l-ijtimāʿ
Incorrect case—the promoted التقرير is nominative, and its adjective must follow it: التقريرُ النهائيُّ.
✅ روجع التقرير النهائي قبل اجتماع اللجنة.
rūjiʿa t-taqrīru n-nihāʾiyyu qabla jtimāʿi l-lajna.
The final report was reviewed before the committee meeting.
Giving a preceding verb full plural agreement
❌ كرموا المهندسون بعد نجاح المشروع.
Incorrect neutral formal VSO—the passive verb preceding the overt masculine plural is singular: كُرِّمَ.
✅ كرم المهندسون بعد نجاح المشروع.
kurrima l-muhandisūna baʿda najāḥi l-mashrūʿ.
The engineers were honored after the project's success.
Using masculine agreement with a preceding feminine subject
❌ كرم الباحثتان بجائزة دولية.
Incorrect gender agreement—the preceding verb must be feminine singular: كُرِّمت.
✅ كرمت الباحثتان بجائزة دولية تقديرا لعملهما.
kurrimati l-bāḥithatāni bijāʾizatin dawliyyatin taqdīran liʿamalihimā.
The two female researchers were honored with an international prize in recognition of their work.
Giving a nonhuman plural human plural agreement
❌ الوثائق نشرن على الموقع.
Incorrect—nonhuman plural الوثائق takes feminine singular نُشرت, not feminine plural نُشرن.
✅ الوثائق نشرت على الموقع صباح اليوم.
al-wathāʾiqu nushirat ʿalā l-mawqiʿi ṣabāḥa l-yawm.
The documents were published on the website this morning.
Calling the promoted entity the doer
❌ الزجاج فاعل لأنه جاء بعد كسر.
Incorrect analysis—in كُسر الزجاجُ, the glass is affected and functions as نائب الفاعل, not semantic agent.
✅ كسر الزجاج أثناء نقل الصندوق.
kusira z-zujāju ʾathnāʾa naqli ṣ-ṣundūq.
The glass was broken while the box was being moved.
Key Takeaways
- نائب الفاعل is the nominative argument promoted when the active agent is suppressed; it is not the semantic doer.
- Promotion changes case: active التقريرَ becomes passive التقريرُ.
- Verb-first human duals and plurals normally follow a singular verb with gender agreement; subject-first human phrases trigger full agreement.
- Nonhuman plurals take feminine singular agreement, while duals retain dual agreement when subject-first.
- With ditransitives, one argument is promoted and another complement can remain accusative: مُنحت الطالبةُ منحةً.
