The Clause Acting as a Noun
The المصدر المؤول (Interpreted Infinitive) is a grammatical unit where a subordinating particle like أنْ (an) or أنَّ (anna) combines with a following clause to act as a single noun. It allows you to express specific actions ('that you go') rather than abstract concepts ('going').
How It Works
The المصدر المؤول (Interpreted Verbal Noun) is a clause that functions as a single noun. In standard Arabic grammar, the المصدر المؤول is inherently definite (معرفة), which allows it to serve as a مبتدأ (subject). To become proficient in this structure, you must recognize these specific particles:
- أنْ + Verb: This particle creates a masdar clause with both present and past verbs. When followed by a present verb, it triggers the subjunctive mood.
- أنّ + Noun + Predicate: A nominal clause following the rules of إنّ and its sisters. Crucially, only the version with the fatha on the hamza (أنّ) creates a Masdar Mu'awwal; the version with the kasra (إنّ) does not.
- ما + Verb: Can be temporal or non-temporal, as seen in ما المصدرية.
- لو + Verb: Used primarily after verbs of wishing or liking.
- كي + Present Verb: Functions as a masdar particle when preceded by the preposition لـ.
- همزة التسوية (أ): Used after words like سواء to turn the following sentence into a noun phrase.
Syntactically, the entire clause occupies a 'place' (maḥall) in the sentence, such as the direct object, the doer, or the pro-agent. A standard method to determine the case is to mentally convert it into an explicit verbal noun. For example, 'أريد أن أذهب' becomes 'أريد الذهاب'.
Advanced Conversion Rules:
1. The Verbal Predicate Rule: If the predicate of أنّ is a verb, convert it using the verbal noun of that specific verb. Example: 'أيقنتُ أنّك تنجحُ' becomes 'أيقنتُ نجاحَك'.
2. The 'Being' (Kawn) Rule: When أنّ is followed by a solid noun (not a derived adjective), use كون. Example: 'أيقنتُ أنّ الرجلَ أسدٌ' becomes 'أيقنتُ كونَ الرجلِ أسداً'.
3. The 'Existence' (Wujud) Rule: If the predicate is a phrase (prepositional or adverbial), use وجود (existence). Example: 'سرّني أنّ الكتابَ هناك' becomes 'سرّني وجودُ الكتابِ هناك'.
4. The 'Negation' (Adam) Rule: To convert a negative clause, use عدم (lack/non-existence) to preserve the meaning. Example: 'يجب أن لا تهملَ' becomes 'يجب عدمُ الإهمالِ'.

- يجب أن تذهبَ.
You must go.
Word by Word: Must that you-go.
A standard 'an' + subjunctive clause acting as the subject of 'yajibu'.
- يسعدني أنك بخير.
It makes me happy that you are well.
Word by Word: Makes-happy-me that-you with-good.
The 'anna' clause here acts as the subject (fāʿil) of the verb 'yas'uduni', showing it is not limited to verbs of reporting.
- سأظل مجتهداً ما دمتُ حياً.
I will remain hardworking as long as I am alive.
Word by Word: I-will-remain hardworking as-long-as I-remained alive.
This is 'mā al-maṣdariyya al-zamaniyya', which turns the clause into a noun indicating duration (the duration of my life).
- اجتهد كي تنجحَ.
Strive so that you succeed.
Word by Word: Strive so-that you-succeed.
The particle 'kay' forms a noun clause expressing purpose, which can be interpreted as 'for your success'.
- ودوا لو ينجحون.
They wished that they would succeed.
Word by Word: Wished-they if they-succeed.
The particle 'law' (if) acts as an interpreting particle after verbs of wishing, forming a noun clause that serves as the object.
- سواءٌ عليهم أأنذرتهم أم لم تنذرهم.
It is the same for them whether you warn them or do not warn them.
Word by Word: Same on them whether you-warned-them or not you-warn-them.
The 'hamzat al-taswiya' (the 'a' of equality) turns the following clause into a noun phrase after the word 'sawāʾ' (same).
Common Mistakes
Using the indicative mood instead of the subjunctive after 'an'.
أريدُ أنْ أذهبُ.أريدُ أنْ أذهبَ.The particle 'an' (أنْ) always requires the following present tense verb to be in the subjunctive (manṣūb), usually ending in a fatḥa.
Confusing 'an' (أنْ) with 'anna' (أنَّ).
أريدُ أنَّ أذهبَ.أريدُ أنْ أذهبَ.Use 'an' (أنْ) before verbs. Use 'anna' (أنَّ) before nouns or attached pronouns.
Failing to put the noun after 'anna' in the accusative case.
أعرفُ أنَّ الجوُّ حارٌ.أعرفُ أنَّ الجوَّ حارٌ.The noun following 'anna' must be in the accusative case (manṣūb) because 'anna' is one of the 'sisters of inna'.
How It Connects
Learn This First
To understand 'المصدر المؤول' (The Interpreted Infinitive), you first need to be comfortable with the particle 'أن' and how it affects the following verb. You also need to understand the concept of the 'Masdar' (Verbal Noun), as this clause acts as a substitute for one. Finally, a grasp of basic sentence roles (I'rab) is necessary to see how this entire clause can function as a subject or object.
- أن + Subjunctive VerbWanting to Do Something
The pattern 'المصدر المؤول' is primarily constructed using 'أن' followed by a present tense verb in the subjunctive mood.

Understanding the concept of the verbal noun (masdar) is essential because the 'المصدر المؤول' functions as a grammatical equivalent to a single verbal noun.
