Leaving Out the Subject
In Arabic, the subject of a sentence can be left out if the context makes it obvious or if the grammar follows a specific idiomatic pattern. This is known as Hadhf al-Mubtada’.
How It Works
1. Optional Omission (Jawāzan):
This occurs most frequently in daily conversation and journalism to avoid redundancy. The most common triggers are:
- Answers to Questions: When asked 'How are you?', the response 'Fine' (بخير) implies 'I am fine.' The subject 'I' (أنا) is omitted.
- Titles and Headings: In books or articles, a title like 'The Subject' (المبتدأ) implies 'This is the subject' (هذا المبتدأ).
- After 'Qawl' (Saying): In reporting, if the topic is already known, the subject is dropped (e.g., 'They said: [It is] a lie').
- After the 'Fa' of Response: Often seen in conditional results, e.g., 'Whoever does good, [it is] for himself.'
2. Obligatory Omission (Wujūban):
In high-register MSA and classical texts, the subject must be omitted in specific structures:
- Verbal Nouns as Predicates (Masdar Nā’ib ‘an Fi’lihi): When a verbal noun replaces its verb to provide stability and emphasis, it acts as the predicate for a hidden subject (e.g., 'Beautiful patience' implying 'My course of action is...').
- Explicit Oaths (Al-Qasam al-Sarīḥ): When the predicate is a phrase like 'In my conscience' (في ذمتي) used as an oath, the subject 'oath' (يمين) is obligatorily hidden.
- After 'La Siyyama': When the noun following 'La Siyyama' is nominative, it is treated as a predicate for a mandatory hidden subject.
- Praise and Blame: In structures like Ni‘ma and Bi’sa, the specific person being praised (Makhsus) is often parsed as a predicate for a hidden subject.
- The Severed Adjective (Na‘t Maqṭū‘): When an adjective unexpectedly takes the nominative case instead of matching its noun, it signals a hidden subject used for praise, blame, or pity.
Examples (6)
- كيف حالُكَ؟ بخيرٍ والحمدُ لله.
How are you? [I am] fine, praise be to God.
Word by Word: How condition-your? In-good and-the-praise to-God.
The subject 'I' (أنا) is optionally omitted in the answer because it is understood from the context of the question.
- مَنْ عَمِلَ صالِحاً فَلِنَفْسِهِ.
Whoever does good, [it is] for himself.
Word by Word: Who worked good so-for-self-his.
After the 'Fa' of response in a conditional sentence, the subject is often omitted. Here, it implies 'so [his work] is for himself'.
- مَرَرْتُ بالرجلِ الكريمُ.
I passed by the man, [he is] the generous one.
Word by Word: I-passed by-the-man the-generous.
This is a 'Severed Adjective' (Na‘t Maqṭū‘). By putting 'the generous' in the nominative case instead of matching the preceding noun, it becomes a predicate for a hidden subject 'He' (هو) used for praise.
- فَصَبْرٌ جَميلٌ.
[My course of action is] beautiful patience.
Word by Word: So-patience beautiful.
This is an obligatory omission where a verbal noun replaces the verb for emphasis, acting as the predicate for a hidden subject like 'my course of action'.
- نِعْمَ القائدُ خالدٌ.
What a great leader Khalid is!
Word by Word: Excellent the-leader Khalid.
In praise and blame structures, one valid parsing is that 'Khalid' is the predicate of an omitted subject 'He' (هو).
- أحبُّ الفواكهَ ولا سيما العنبُ.
I love fruits, especially grapes.
Word by Word: I-love the-fruits and-not like-what the-grapes.
After 'La Siyyama', if the following noun is in the nominative case, it is parsed as the predicate of an obligatorily omitted subject.
Common Mistakes
Confusing subject omission with predicate omission after 'Lawla'.
لولا المطرُ موجودٌ لذهبنا.لولا المطرُ لذهبنا.After لولا, it is the predicate that is usually omitted, not the subject. In 'Hadhf al-Mubtada', the subject is the part that goes missing.
Thinking the genitive adjective is a mistake.
Different Meaningمررتُ بالرجلِ المسكينِ.مررتُ بالرجلِ المسكينُ.Both are correct. The genitive المسكينِ is a plain description. The nominative المسكينُ is a "cut" adjective that starts a new phrase ("the poor man") and adds pity.
How It Connects
Learn This First
To understand the omission of the subject (حذف المبتدأ), you must first be comfortable with the standard structure of an Arabic nominal sentence, which consists of a subject (mubtada') and a comment (khabar). Since this omission often occurs in response to questions or in situational contexts where a pronoun is implied, you should also be familiar with basic personal pronouns and how sentences function without a verb.
- Subject and Comment
Understanding the basic structure of the nominal sentence (Subject and Comment) is essential before learning when the subject can be omitted.
Level 1 - أنا / أنت / هوPersonal Pronouns (Singular)
Omitted subjects are often personal pronouns that are understood from context, so familiarity with these pronouns is required.

Level 1 - Leaving Out the Verb
The counterpart to subject omission, where the verb is left out instead of the nominal subject.
Level 5 - لولاIf It Were Not for
Often confused with subject omission because it involves a mandatory deletion of the predicate.
Level 5 - نِعْمَ / بِئْسَPraise and Blame
A formal structure that frequently triggers the obligatory omission of the subject.
Level 4 - The Subject Ending
The nominative case is the primary indicator that a word is a predicate for an omitted subject.
