An Arabic predicate is the information supplied about a subject or topic. It may be a noun, an adjective, an adverbial phrase, or an entire clause. These different shapes all do the same larger job: together with the subject, they create a complete predication.
The most useful starting point is Arabic itself, not an English sentence with an imagined missing is. In a present affirmative nominal sentence, Arabic directly joins the subject to the information about it. The introductory pattern is reviewed in The Present Nominal Sentence; here we expand the range of possible predicates.
Phrase or complete predication?
Definiteness often tells you whether an adjective belongs inside a noun phrase or functions as a predicate. Compare this minimal pair:
التقرير المفصل
at-taqrīru l-mufaṣṣal
the detailed report (a noun phrase, not a complete sentence)
التقرير مفصل.
at-taqrīru mufaṣṣal.
The report is detailed. (A complete predication.)
In the phrase, both التقرير and its adjective المفصل are definite. In the sentence, definite التقرير establishes what is being discussed, while indefinite مفصل provides new information. Punctuation may show where a writer intends the sentence to end, but punctuation alone does not create predication: the grammatical relationship does.
Noun predicates identify or classify
A noun predicate places the subject in a profession, role, category, or identity. In the neutral present pattern, the initial subject is usually definite and the classifying predicate is indefinite.
نادية مهندسة معمارية.
nādiyatu muhandisatun miʿmāriyya(h).
Nadia is an architect.
هذه الغرفة مكتبة صغيرة.
hādhihi l-ghurfatu maktabatun ṣaghīra(h).
This room is a small library.
In fully inflected (formal) MSA, both the basic subject and a one-word noun predicate are nominative: ناديةُ مهندسةٌ. Ordinary formal speech often suppresses the last case ending at a pause, but the syntactic analysis remains the same.
When both sides are definite, Arabic may use a separating pronoun to prevent the second phrase from being mistaken for an adjective or apposition and to sharpen identification: نادية هي المديرة “Nadia is the director.” That focused identification is not the default for classifying someone as مهندسة.
Adjective predicates describe and agree
An adjective predicate agrees with its subject in gender and number, subject to Arabic's special rule for nonhuman plurals.
الممرضة مستعدة الآن.
al-mumarriḍatu mustaʿiddatun al-ʾān.
The nurse is ready now.
المتطوعون مستعدون للانطلاق.
al-mutaṭawwiʿūna mustaʿiddūna lil-inṭilāq.
The volunteers are ready to leave.
النوافذ مفتوحة هذا الصباح.
an-nawāfidhu maftūḥatun hādhā ṣ-ṣabāḥ.
The windows are open this morning. (Nonhuman plural with feminine-singular agreement.)
The plural النوافذ does not take مفتوحات in this meaning. Nonhuman plurals normally control feminine-singular agreement. Human plurals such as المتطوعون normally take plural agreement.
Negation introduces ليس, an overt inflecting word. A single-word predicate after it is accusative in fully inflected MSA:
القاعة ليست مزدحمة اليوم.
al-qāʿatu laysat muzdaḥimatan al-yawm.
The hall is not crowded today.
Adverbial predicates locate, date, or relate
An adverbial predicate can be a prepositional phrase such as في المكتب or a time/place expression such as غدا and أمام المبنى. The phrase as a whole predicates a location, time, possession, or relation; it is not a noun predicate with an omitted preposition.
النسخة الأصلية في الخزانة.
an-nuskhatu l-ʾaṣliyyatu fī l-khizāna(h).
The original copy is in the cabinet.
موعد التسليم بعد غد.
mawʿidu t-taslīmi baʿda ghad.
The delivery deadline is the day after tomorrow.
Arabic can reverse the neutral subject–predicate order when a location introduces something new:
أمام المبنى سيارة إسعاف.
ʾamāma l-mabnā sayyāratu ʾisʿāf.
There is an ambulance in front of the building. (Fronted predicate + delayed subject.)
Here أمام المبنى is the predicate even though it comes first, and سيارة إسعاف is the delayed subject. Arabic has no dummy equivalent of English there. The first phrase is therefore not automatically the subject.
A whole clause can be the predicate
The comment about a topic may itself be a verbal or nominal clause. Arabic normally makes the link back to the topic visible through agreement or a resumptive pronoun.
الأطفال يلعبون في الحديقة.
al-ʾaṭfālu yalʿabūna fī l-ḥadīqa(h).
The children are playing in the garden. (Verbal-clause predicate.)
المشروع ميزانيته محدودة.
al-mashrūʿu mīzāniyyatuhu maḥdūda(h).
As for the project, its budget is limited. (Nominal-clause predicate with a resumptive possessive pronoun.)
In the first sentence, يلعبون agrees with الأطفال and forms the predicate clause. In the second, the attached ـه in ميزانيته links the internal clause “its budget is limited” back to المشروع. English often says “The project's budget is limited”; Arabic topic–comment structure makes the two-layer analysis especially clear.
Present, past, and future frames
The zero-copula pattern is a present affirmative construction. Past and future relations normally need كان or سيكون, and a simple noun or adjective predicate becomes accusative.
كان المكتب هادئا في الصباح.
kāna l-maktabu hādiʾan fī ṣ-ṣabāḥ.
The office was quiet in the morning.
سيكون الاجتماع في القاعة الكبرى.
sa-yakūnu l-ijtimāʿu fī l-qāʿati l-kubrā.
The meeting will be in the main hall.
The locative predicate في القاعة الكبرى does not acquire an accusative ending as a unit; the preposition continues to govern its noun. Tense support changes the clause frame, not the internal grammar of a prepositional phrase.
A short exchange
هل العرض جاهز؟
hali l-ʿarḍu jāhiz?
Is the presentation ready?
ليس بعد، لكن النسخة الأولى عند المدير.
laysa baʿdu, lakini n-nuskhatu l-ʾūlā ʿinda l-mudīr.
Not yet, but the first draft is with the director.
The response contains an understood answer after ليس بعد and then a complete nominal sentence whose predicate is عند المدير.
Common Mistakes
Inserting present-tense “be”
❌ التقرير يكون جاهزا للاجتماع الآن.
Incorrect for the neutral present meaning—yakūnu is not a required equivalent of English ‘is.’
✅ التقرير جاهز الآن.
at-taqrīru jāhizun al-ʾān.
The report is ready now.
Adding a dummy “there” or “it”
❌ هو أمام المبنى سيارة إسعاف.
Incorrect—huwa must refer to a real masculine entity; it cannot be a dummy existential subject.
✅ أمام المبنى سيارة إسعاف تنتظر.
ʾamāma l-mabnā sayyāratu ʾisʿāfin tantaẓir.
There is an ambulance waiting in front of the building.
Treating every initial noun as the inner subject
❌ المشروع هو فاعل ميزانيته محدودة.
Incorrect analysis—the project is the outer topic, while mīzāniyyatuhu is the subject inside the predicate clause.
✅ المشروع ميزانيته محدودة جدا.
al-mashrūʿu mīzāniyyatuhu maḥdūdatun jiddan.
As for the project, its budget is very limited.
Importing an English comma into a short predicate chain
❌ الغرفة واسعة، ومضيئة.
Poor punctuation in a short coordinated predicate—Arabic does not require an English-style comma before wa-.
✅ الغرفة واسعة ومضيئة أيضا.
al-ghurfatu wāsiʿatun wa-muḍīʾatun ʾayḍan.
The room is spacious and bright as well.
Key Takeaways
- A predicate may be a noun, adjective, adverbial phrase, or complete clause.
- Present affirmative predication needs no form of be; ليس handles ordinary present negation, while كان and سيكون support past and future frames.
- Noun and adjective predicates show case and agreement; phrase predicates retain their own internal government.
- A clause predicate must link back to its topic through agreement or resumption.
- Word order reflects information structure: a fronted location may be the predicate, not the subject.
