Formal Arabic can turn an event or proposition into a unit that occupies a noun phrase's position. It can use a lexical maṣdar such as تأجيل المشروع “postponement of the project,” light أنْ + subjunctive such as أن يتأجل المشروع “for the project to be postponed,” or heavy أنَّ + proposition such as أنَّ المشروعَ تأجّل “that the project was postponed.” All three can be called “nominalized” in a broad sense, but their internal grammar and communicative effects differ.
English often hides this choice behind -ing, to, and that. Arabic makes a more useful distinction: a maṣdar presents an event as a noun-like object; light أنْ retains a finite, person-marked event; heavy أنَّ embeds a proposition whose truth, report, or evaluation is at issue. This page focuses on building dense C1 prose without losing track of who did what to whom.
For the morphology and basic distribution behind this synthesis, review choosing a maṣdar or أنْ-clause and content clauses with أنَّ.
Three packages, three internal grammars
| Package | Internal structure | What stays visible | Typical use |
|---|---|---|---|
| lexical maṣdar | declined noun + nominal complements | case, definiteness, iḍāfa; no person or tense | named process, policy, institutional action |
| أَنْ + imperfect | finite subjunctive clause | subject agreement, voice, negation, relative time | projected, desired, possible, or evaluated event |
| أَنَّ + proposition | accusative noun + predicate | a complete fact-like claim | knowledge, report, evidence, conclusion |
The governor outside the package determines its external role. In ناقشت اللجنةُ تأجيلَ المشروعِ, the whole maṣdar phrase is the accusative object of ناقشت. In أثار تأجيلُ الوزارةِ إطلاقَ المشروعِ أسئلةً, it is the nominative subject of أثار. The event noun can therefore govern participants internally while receiving a different case from the larger sentence.
أثار تأجيل الوزارة إطلاق المشروع أسئلة قانونية.
ʾathāra taʾjīlu l-wizārati ʾiṭlāqa l-mashrūʿi ʾasʾilatan qānūniyya.
The ministry's postponement of the project's launch raised legal questions. (Formal; fully parsed maṣdar phrase.)
Here تأجيلُ is nominative as the subject of أثار; الوزارةِ is its genitive agent in iḍāfa; إطلاقَ is the accusative object governed by تأجيل; and المشروعِ completes a second iḍāfa. The chain is grammatical, but it makes the reader hold several relations in memory.
أخرت الوزارة إطلاق المشروع، فأثار القرار أسئلة قانونية.
ʾakhkharati l-wizāratu ʾiṭlāqa l-mashrūʿi, fa-ʾathāra l-qarāru ʾasʾilatan qānūniyya.
The ministry postponed the project's launch, and the decision raised legal questions. (Clearer finite paraphrase.)
Realizing the maṣdar's arguments
An active transitive maṣdar can retain verbal argument structure. A following genitive in iḍāfa commonly names its agent, while a retained direct object is accusative: مراجعةُ اللجنةِ الخطةَ “the committee's review of the plan.” If only one genitive follows, meaning and lexical knowledge must identify its role: إغلاقُ المصنعِ can mean “the factory's closing” or “the closure of the factory.”
أوصت الهيئة بمراجعة اللجنة الخطة قبل اعتمادها.
ʾawṣati l-hayʾatu bi-murājaʿati l-lajnati l-khuṭṭata qabla ʿtimādihā.
The authority recommended that the committee review the plan before approving it. (Formal; اللجنةِ is agent, الخطةَ is object.)
Contemporary prose often uses a prepositional complement to reduce ambiguity: مراجعة اللجنة للخطة. That version makes الخطة visibly genitive after لـ and prevents a long run of adjacent nouns from looking like one undifferentiated iḍāfa.
رحب الخبراء بمراجعة مستقلة للبيانات قبل نشر النتائج.
raḥḥaba l-khubarāʾu bi-murājaʿatin mustaqillatin lil-bayānāti qabla nashri n-natāʾij.
The experts welcomed an independent review of the data before publication of the results. (Formal/academic; explicit لـ complement.)
An attached pronoun can identify an agent or affected participant, but not by form alone. تقييمهم may mean “their evaluation” or “evaluating them.” Add a following object, a preposition, or a finite clause when the intended roles would otherwise remain genuinely ambiguous.
Maṣdar versus light أنْ
Light أنْ governs an imperfect subjunctive. Because the verb still agrees with its subject, it is often the better choice when participants differ, negation matters, or the event has an internal time structure.
طلبت المديرة من القسم إعداد الميزانية الجديدة.
ṭalabati l-mudīratu mina l-qismi ʾiʿdāda l-mīzāniyyati l-jadīda.
The director requested the preparation of the new budget by the department. (Compact administrative style.)
طلبت المديرة من القسم أن يعد الميزانية الجديدة قبل الجمعة.
ṭalabati l-mudīratu mina l-qismi ʾan yuʿidda l-mīzāniyyata l-jadīdata qabla l-jumuʿa.
The director asked the department to prepare the new budget before Friday. (The clause exposes the actor and deadline.)
The first version treats preparation as the requested institutional product. The second makes القسم the understood subject of subjunctive يعدَّ. Neither is intrinsically more correct; the clause simply carries more event structure.
نخشى ألا تكشف المراجعة سبب الخلل في الوقت المتاح.
nakhshā ʾallā takshifa l-murājaʿatu sababa l-khalali fī l-waqti l-mutāḥ.
We fear that the review may not reveal the cause of the fault in the available time. (Formal; negation remains inside the event clause.)
A nominal equivalent such as نخشى عدم كشف المراجعة سبب الخلل is possible (formal/administrative), but its nested arguments are harder to process. عدم + maṣdar is productive, not automatically elegant.
Maṣdar versus heavy أنَّ
Heavy أنَّ introduces a proposition. Its noun is accusative, while its predicate follows the syntax appropriate to a nominal clause. It does not govern the mood of a following verb.
أكد التقرير انخفاض التكاليف خلال الربع الأخير.
ʾakkada t-taqrīru nkhifāḍa t-takālīfi khilāla r-rubʿi l-ʾakhīr.
The report confirmed the decline in costs during the last quarter. (The decline is packaged as a measured phenomenon.)
أكد التقرير أن التكاليف انخفضت خلال الربع الأخير.
ʾakkada t-taqrīru ʾanna t-takālīfa nkhafaḍat khilāla r-rubʿi l-ʾakhīr.
The report confirmed that costs fell during the last quarter. (The full proposition is asserted.)
This is a minimal information-structure contrast, not a tense contrast. The maṣdar foregrounds الانخفاض as a phenomenon; the أنَّ clause foregrounds the claim that a fall occurred. With complex polarity, attribution, or contrast, the clausal version is usually clearer.
Register: density has a cost
Maṣdar-heavy wording is productive in legal, administrative, journalistic, and academic Arabic (formal/academic). It can suppress an irrelevant agent and align several processes: جمع البيانات وتحليلها ونشرها. It can also create opaque “noun stacks” that force readers to reconstruct several hidden predicates.
يهدف البرنامج إلى توسيع خدمات الرعاية وتحسين توزيعها من دون أن تتحمل الأسر تكاليف إضافية.
yahdifu l-barnāmaju ʾilā tawsīʿi khidmāti r-riʿāyati wa-taḥsīni tawzīʿihā min dūni ʾan tataḥammala l-ʾusaru takālīfa ʾiḍāfiyya.
The program aims to expand care services and improve their distribution without families bearing additional costs. (Formal policy prose.)
The two coordinated maṣdars efficiently name policy goals. The final أنْ clause is clearer than another nominalization because it identifies الأسر as the bearer of the cost. Formal style is strongest when density is selective.
Common Mistakes
Assigning case by English order
❌ أثار تأجيل الوزارة إطلاق المشروع أسئلة، وتأجيل منصوب لأنه يأتي بعد الفعل.
Incorrect analysis—تأجيل is the subject of أثار and is nominative; the immediately postverbal position does not make it an object.
✅ أثار تأجيل الوزارة إطلاق المشروع اعتراضات جديدة.
ʾathāra taʾjīlu l-wizārati ʾiṭlāqa l-mashrūʿi ʿtirāḍātin jadīda.
The ministry's postponement of the project's launch raised new objections.
Making the maṣdar's object genitive by adjacency
❌ أوصت الهيئة بمراجعة اللجنة الخطة على أن الخطة مجرورة بالإضافة.
Incorrect analysis—اللجنةِ fills the iḍāfa slot as agent; retained object الخطةَ is accusative.
✅ دعمت الهيئة مراجعة اللجنة الخطة بصورة مستقلة.
daʿamati l-hayʾatu murājaʿata l-lajnati l-khuṭṭata bi-ṣūratin mustaqilla.
The authority supported the committee's independent review of the plan.
Merging the governors of أنْ and أنَّ
❌ توقعت اللجنة أن النتائج تنخفض بسرعة.
Incorrect hybrid—either use light أنْ with subjunctive تنخفضَ and a nominative following subject, or heavy أنّ with accusative النتائجَ and indicative تنخفضُ.
✅ توقعت اللجنة أن تنخفض النتائج تدريجيا.
tawaqqaʿati l-lajnatu ʾan tankhafiḍa n-natāʾiju tadrījiyyan.
The committee expected the results to decline gradually.
Treating maximum nominal density as neutral style
❌ تم إجراء دراسة إمكانية تنفيذ عملية إعادة تنظيم توزيع الموارد.
Grammatically recoverable but needlessly opaque—the stacked nominalizations hide the decision, action, and participants.
✅ درست الإدارة إمكان أن تعيد توزيع الموارد بين الفروع.
darasati l-ʾidāratu ʾimkāna ʾan tuʿīda tawzīʿa l-mawāridi bayna l-furūʿ.
The administration studied the possibility of redistributing resources among the branches. (Clear formal MSA.)
Key Takeaways
- A lexical maṣdar is a declined noun with potentially verb-like argument structure; its external case and internal participants must be analyzed separately.
- Light أنْ keeps a finite subjunctive event, while heavy أنَّ embeds a proposition with an accusative noun.
- Use clauses when subject identity, polarity, voice, or relative time matters; use maṣdars when treating an event as a named process genuinely improves the discourse.
- Formal MSA values compact nominal style, but a chain is not sophisticated if readers cannot recover its governors and participant roles.
