Matching the Article on Adjectives
To say 'the big house,' both 'house' and 'big' need the definite article al- (الـ). If only the noun has it, you've made a sentence: 'The house is big.'
How It Works
In Modern Standard Arabic, adjectives are not just words that describe; they are grammatical 'followers' (tābi‘). One of the most important ways they follow is in definiteness.
- The Double 'Al-' Rule: When you want to form a phrase like 'the new book,' you must apply the definite article al- to both words: الكتاب الجديد (al-kitāb al-jadīd).
- Indefinite Phrases: If the noun is indefinite (meaning 'a' or 'some'), the adjective remains indefinite: كتاب جديد (kitāb jadīd - a new book).
- Hidden Definiteness: A noun can be definite without the al- prefix. This happens if it has a possessive suffix (like 'my') or is a proper name (like 'London'). In these cases, the adjective still requires the al- prefix to show it is describing that specific noun.
- The Sentence Trap: If you put al- on the noun but leave the adjective indefinite, you have created a complete sentence. For example, البيت كبير means 'The house [is] big,' not 'the big house.'
Examples (4)
- البيتُ الكبيرُ جميلٌ.
The big house is beautiful.
Word by Word: The-house the-big beautiful.
Here, 'the big house' is a phrase where both the noun and adjective take 'al-' to match.
- سكنتُ في مدينةٍ قديمةٍ.
I lived in an old city.
Word by Word: I-lived in city old.
Since 'city' is indefinite (a city), the adjective 'old' also remains indefinite.
- سيارتي الجديدةُ سريعةٌ.
My new car is fast.
Word by Word: Car-my the-new fast.
The noun 'car' is definite because of the 'my' suffix. Therefore, the adjective 'new' must take 'al-' to match it.
- قابلتُ محمداً الكريمَ.
I met the generous Muhammad.
Word by Word: I-met Muhammad the-generous.
Proper names are definite by nature. The adjective 'generous' needs 'al-' to correctly describe Muhammad.
Common Mistakes
Writing a sentence when 'the tall boy' is meant.
Different Meaningالولد طويلالولد الطويل'الولد طويل' means 'The boy is tall' (a sentence). To say 'the tall boy' (a phrase), you must repeat the 'al-' on the adjective.
Writing 'my book is new' when 'my new book' is meant.
Different Meaningكتابي جديدكتابي الجديدIf you mean 'my new book,' you need 'al-' on the adjective because 'my book' is already definite. Without 'al-', it means 'My book is new.'
How It Connects
Learn This First
To understand how adjectives match nouns in definiteness, you first need to know how the definite article (Al-) works and the basic rule that adjectives follow the noun in Arabic. Additionally, understanding the Subject-Comment structure is crucial because the presence or absence of the definite article on the adjective is what distinguishes a phrase (the big house) from a complete sentence (the house is big).

Understanding the basic concept of adjectives following nouns is necessary before learning specific rules of agreement like definiteness.
