Nominal vs Verbal Sentences: How Arabic Builds Every Sentence
Every sentence you will ever read in Modern Standard Arabic belongs to one of two families. If it opens with a noun or pronoun, it is a nominal sentence (الجُمْلَة الاسْمِيَّة, al-jumla al-ismiyya). If it opens with a verb, it is a verbal sentence (الجُمْلَة الفِعْلِيَّة, al-jumla al-fi'liyya). That single opening word decides the structure, the agreement rules, and even the emphasis of everything that follows.
This split is the first big idea in Arabic grammar, and it explains things that puzzle English speakers from day one: why 'The book is new' has no word for 'is', and why 'The boys went' can use a singular verb. Once you see the two patterns clearly, most beginner Arabic sentences stop looking mysterious.
In this guide we break down both sentence types, the subject and predicate of the nominal sentence (mubtada' and khabar), the verb-subject-object order of the verbal sentence, and the agreement rule that changes depending on which comes first.
The Two Sentence Types at a Glance
Arabic classifies sentences by their first word, not by whether they contain a verb somewhere. A nominal sentence starts with a noun or pronoun and makes a statement about it. A verbal sentence starts with a verb and reports an action.
Both types are fully grammatical and extremely common in Modern Standard Arabic. Verbal sentences dominate narration and news writing, while nominal sentences dominate descriptions, definitions, and everyday statements about states and qualities.
- Nominal sentence (جُمْلَة اسْمِيَّة): begins with a noun or pronoun, e.g. 'The book is new'
- Verbal sentence (جُمْلَة فِعْلِيَّة): begins with a verb, e.g. 'The student wrote the lesson'
- The choice between them changes agreement rules and emphasis, not correctness
Inside the Nominal Sentence: Mubtada' and Khabar
A nominal sentence has two parts. The مُبْتَدَأ (mubtada') is the subject: a noun or pronoun, almost always definite, carrying the nominative case ending -u. The خَبَر (khabar) is the predicate: the information given about the subject, usually indefinite, also in the nominative case with -un.
The most striking feature for English speakers is that there is no verb 'to be' in the present tense. Arabic simply places the subject next to the predicate: الطَّالِبُ ذَكِيٌّ literally reads 'the-student smart', and that is a complete, correct sentence meaning 'The student is smart'.
The khabar does not have to be an adjective. It can be another noun, a prepositional phrase such as 'in the house', or even a whole embedded sentence.
The Definiteness Trick: Sentence or Phrase?
Because there is no visible 'is', Arabic uses definiteness to tell a sentence apart from a mere description. If the second word is indefinite, you have a sentence. If both words are definite, you have a phrase, not a sentence.
Compare المُعَلِّمُ جَدِيدٌ (al-mu'allimu jadīdun), 'The teacher is new', with المُعَلِّمُ الجَدِيدُ (al-mu'allimu al-jadīdu), 'the new teacher'. The only difference is the definite article on the second word, yet one is a complete statement and the other is just a noun phrase waiting for more.
This tiny rule does a huge amount of work in reading comprehension, and it is one of the first things to check when a sentence refuses to make sense.
Inside the Verbal Sentence: VSO Word Order
Verbal sentences follow the order verb + subject + object: فِعْل (fi'l) + فَاعِل (fā'il) + مَفْعُول بِهِ (maf'ūl bihi). This VSO order is the default in Modern Standard Arabic, the opposite of English SVO.
The subject of a verbal sentence takes the nominative case, and the direct object takes the accusative case, marked with -a. In كَتَبَ الطَّالِبُ الدَّرْسَ, the subject aṭ-ṭālibu ends in -u and the object ad-darsa ends in -a. The case endings, not the position, tell you who did what to whom.
The Agreement Rule That Surprises Everyone
Here is the rule that separates careful learners from confused ones. When the verb comes before the subject, it agrees in gender only and stays singular, no matter how many people are doing the action. That is why 'The boys went' is ذَهَبَ الأَوْلَادُ with a singular verb, never ذَهَبُوا الأَوْلَادُ.
When the subject comes first, the sentence technically becomes a nominal sentence with a verbal predicate, and now the verb agrees fully in both gender and number: المُعَلِّمُونَ جَاؤُوا, 'The teachers came', uses the plural verb because the subject came first.
Keep the pair جَاءَ المُعَلِّمُونَ and المُعَلِّمُونَ جَاؤُوا in mind as your reference. Same meaning, different order, different agreement.
- Verb first (VSO): verb agrees in gender only and stays singular
- Subject first (SVO): verb agrees in gender and number
- This applies to duals too: نَامَتِ الطِّفْلَتَانِ but الطِّفْلَتَانِ نَامَتَا
Which Order Should You Choose?
Both structures are correct, so the choice is about emphasis. Starting with the verb highlights the action, which suits storytelling and reporting: سَافَرَ أَحْمَدُ إِلَى لُنْدُن focuses on the traveling. Starting with the subject highlights the doer or topic: أَحْمَدُ سَافَرَ إِلَى لُنْدُن answers the question 'What did Ahmad do?'.
As a practical rule for learners, default to verb-first when narrating events and noun-first when describing people, places, and states. Then listen for how native texts flip the order to shift focus.

Frequently asked questions
Why is there no word for 'is' in Arabic sentences like 'The book is new'?
Arabic nominal sentences do not use a verb in the present tense. Placing a definite subject next to an indefinite predicate, as in al-kitābu jadīdun, already forms a complete sentence. A verb (kāna) appears only when you shift to the past or future.
Is Arabic a VSO or SVO language?
Modern Standard Arabic uses VSO as the default order in verbal sentences, but subject-first order is also fully grammatical and common. The two orders differ in emphasis and in verb agreement, not in correctness.
Why does Arabic use a singular verb with a plural subject?
When the verb precedes its subject, it agrees in gender only and remains singular: dhahaba al-awlādu, 'the boys went'. Full number agreement applies only when the subject comes before the verb: al-awlādu dhahabū.
How can I tell 'the new teacher' from 'The teacher is new'?
Check the definiteness of the second word. If it carries the definite article (al-mu'allimu al-jadīdu), it is a descriptive phrase. If it is indefinite (al-mu'allimu jadīdun), it is a complete sentence meaning 'The teacher is new'.
