Arabic Adjectives: Agreement, Placement, and Comparison
Arabic adjectives are one of the most fascinating — and initially tricky — parts of Arabic grammar. Unlike English adjectives, which stay the same no matter what noun they describe, Arabic adjectives change form to match the noun they modify. They adapt for gender, number, and definiteness, and they follow specific rules for placement and comparison.
Once you understand the system, it's remarkably logical and consistent. This guide will walk you through everything you need to know about Arabic descriptive words: how they agree with nouns, where they appear in a sentence, and how to form comparative and superlative expressions.
If you're just starting out with Arabic grammar, you may want to first read our Arabic Grammar Basics: A Beginner's Roadmap to Mastering the Language before diving in here.
What Are Arabic Adjectives?
An adjective is a word that describes or modifies a noun — words like big, beautiful, new, or fast. In Arabic, adjectives are called نَعْت (naʿt) or صِفَة (ṣifa), meaning "description" or "attribute."
Some common Arabic adjectives you'll encounter include:
| Arabic | Transliteration | Meaning |
|---|---|---|
| كَبِير | kabīr | big |
| صَغِير | ṣaghīr | small |
| جَدِيد | jadīd | new |
| قَدِيم | qadīm | old |
| جَمِيل | jamīl | beautiful |
| سَرِيع | sarīʿ | fast |
| بَطِيء | baṭīʾ | slow |
| طَوِيل | ṭawīl | tall/long |
| قَصِير | qaṣīr | short |
| كَرِيم | karīm | generous |
These are the masculine singular base forms. From here, Arabic adjectives must be modified to agree with the nouns they describe.

Arabic Adjective Agreement: Gender
Arabic has two grammatical genders: masculine (مُذَكَّر, mudhakkar) and feminine (مُؤَنَّث, muʾannatth). Every noun has a gender, and every adjective must match it.
Forming the Feminine Adjective
The most common way to make an adjective feminine is to add the tā' marbūṭa (ة) ending to the masculine form.
| Masculine | Feminine | Meaning |
|---|---|---|
| كَبِير (kabīr) | كَبِيرَة (kabīra) | big |
| جَمِيل (jamīl) | جَمِيلَة (jamīla) | beautiful |
| جَدِيد (jadīd) | جَدِيدَة (jadīda) | new |
| صَغِير (ṣaghīr) | صَغِيرَة (ṣaghīra) | small |
| طَوِيل (ṭawīl) | طَوِيلَة (ṭawīla) | tall/long |
Examples in context:
- بَيْتٌ كَبِيرٌ (baytun kabīrun) — a big house [masculine]
- سَيَّارَةٌ كَبِيرَةٌ (sayyāratun kabīratun) — a big car [feminine]
- رَجُلٌ جَمِيلٌ (rajulun jamīlun) — a handsome man [masculine]
- امْرَأَةٌ جَمِيلَةٌ (imraʾatun jamīlatun) — a beautiful woman [feminine]
Broken Plural Adjectives and Non-Human Plurals
An important rule in Arabic: when adjectives describe non-human plural nouns (objects, animals, things), the adjective takes the feminine singular form. This is a crucial concept for learners!
- كُتُبٌ كَثِيرَةٌ (kutubun kathīratun) — many books (kutub = books, plural of kitāb)
- بُيُوتٌ كَبِيرَةٌ (buyūtun kabīratun) — big houses
- سَيَّارَاتٌ سَرِيعَةٌ (sayyārātun sarīʿatun) — fast cars
For human plurals, adjectives take full plural forms (discussed in the next section).
Arabic Adjective Agreement: Number
Arabic adjectives also change based on whether the noun is singular, dual, or plural.
Singular
Use the base masculine or feminine form as shown above.
Dual
For dual nouns (referring to exactly two of something), adjectives also take a dual ending:
- Masculine dual adjective: add -ān (ـَانِ) in nominative, -ayn (ـَيْنِ) in other cases
- Feminine dual adjective: add -atān (ـَتَانِ) nominative
Examples:
- رَجُلَانِ طَوِيلَانِ (rajulāni ṭawīlāni) — two tall men
- امْرَأَتَانِ جَمِيلَتَانِ (imraʾatāni jamīlatāni) — two beautiful women
Human Plural
For human plural nouns, adjectives take specific plural forms. Many Arabic adjectives form their plural using a broken plural pattern (an internal vowel change), while others simply take a sound plural suffix.
Sound masculine plural: add -ūn (ـُونَ) nominative / -īn (ـِينَ) other
- مُعَلِّمُونَ مَاهِرُونَ (muʿallimūna māhirūna) — skilled teachers (male)
Sound feminine plural: add -āt (ـَاتٌ)
- مُعَلِّمَاتٌ مَاهِرَاتٌ (muʿallimātun māhirātun) — skilled teachers (female)
Non-human plural: Always uses feminine singular adjective form (as mentioned above).
Arabic Adjective Agreement: Definiteness
One of the unique features of Arabic adjective agreement is definiteness. If the noun has the definite article الـ (al-, meaning "the"), the adjective must also carry الـ.
| Noun | Adjective | Translation |
|---|---|---|
| بَيْتٌ (indefinite) | كَبِيرٌ | a big house |
| الْبَيْتُ (definite) | الْكَبِيرُ | the big house |
| سَيَّارَةٌ (indefinite) | جَدِيدَةٌ | a new car |
| السَّيَّارَةُ (definite) | الْجَدِيدَةُ | the new car |
Important: If the noun has al- but the adjective does not, the structure becomes a predicate sentence ("The house is big") rather than an adjective phrase. More on this below.
Placement of Arabic Adjectives
In Arabic, adjectives come after the noun they describe — the opposite of English. This is one of the first rules learners notice.
English: a beautiful city
Arabic: مَدِينَةٌ جَمِيلَةٌ (madīnatun jamīlatun) — literally "a city beautiful"
English: the new teacher
Arabic: الْمُعَلِّمُ الْجَدِيدُ (al-muʿallimu al-jadīdu) — literally "the teacher the new"
Adjective vs. Predicate Position
Here's where definiteness and placement interact in an important way:
Adjective phrase (noun + matching adjective): Both have al- → describes the noun
- الْكِتَابُ الْجَدِيدُ = the new book
Predicate sentence (noun is definite, adjective is indefinite): Creates a complete sentence meaning "The X is Y"
- الْكِتَابُ جَدِيدٌ = The book is new.
This distinction is fundamental to Arabic sentence construction. For a deeper look at how Arabic sentences work, see our guide on Arabic Sentence Structure: How to Build Sentences.
Multiple Adjectives
When multiple adjectives modify a single noun, they all follow the noun in sequence, each agreeing in gender, number, and definiteness:
بَيْتٌ كَبِيرٌ جَدِيدٌ جَمِيلٌ
baytun kabīrun jadīdun jamīlun
a big, new, beautiful houseالْبَيْتُ الْكَبِيرُ الْجَدِيدُ الْجَمِيلُ
al-baytu al-kabīru al-jadīdu al-jamīlu
the big, new, beautiful house
The Arabic Comparative: Comparing Two Things
To say something is "more" than something else — bigger, faster, more beautiful — Arabic uses a specific form called أَفْعَل (afʿal), known as the elative form.
Forming the Comparative (أَفْعَل Pattern)
The comparative is formed by placing the root letters of the adjective into the pattern أَفْعَل:
| Base Adjective | Root | Comparative | Meaning |
|---|---|---|---|
| كَبِير (kabīr) | ك-ب-ر | أَكْبَر (akbar) | bigger |
| صَغِير (ṣaghīr) | ص-غ-ر | أَصْغَر (aṣghar) | smaller |
| كَثِير (kathīr) | ك-ث-ر | أَكْثَر (akthar) | more |
| قَلِيل (qalīl) | ق-ل-ل | أَقَلّ (aqall) | less/fewer |
| جَمِيل (jamīl) | ج-م-ل | أَجْمَل (ajmal) | more beautiful |
| سَرِيع (sarīʿ) | س-ر-ع | أَسْرَع (asraʿ) | faster |
| طَوِيل (ṭawīl) | ط-و-ل | أَطْوَل (aṭwal) | taller/longer |
| قَصِير (qaṣīr) | ق-ص-ر | أَقْصَر (aqṣar) | shorter |

Using the Comparative in a Sentence
To compare two things, use the structure:
[Subject] + أَفْعَل + مِنْ + [compared noun]
The word مِنْ (min) means "than" in comparative sentences.
Examples:
هَذَا الْبَيْتُ أَكْبَرُ مِنْ ذَلِكَ الْبَيْتِ
Hādhā al-baytu akbaru min dhālika al-bayti
This house is bigger than that house.مُحَمَّدٌ أَطْوَلُ مِنْ عَلِيٍّ
Muḥammadun aṭwalu min ʿAliyyin
Muhammad is taller than Ali.هَذِهِ السَّيَّارَةُ أَسْرَعُ مِنْ تِلْكَ
Hādhihi al-sayyāratu asraʿu min tilka
This car is faster than that one.
An Important Rule: The Comparative Doesn't Change for Gender
Unlike regular adjectives, the أَفْعَل comparative form does not change for gender or number when used in a direct comparison with مِنْ. It remains in its base masculine form:
- فَاطِمَةُ أَجْمَلُ مِنْ سَارَة (Fāṭimatu ajmalu min Sāra) — Fatima is more beautiful than Sara. (ajmal stays masculine even though the subject is female)
The Arabic Superlative: The Most
Interestingly, Arabic uses the same أَفْعَل form for both comparative and superlative meanings — the difference lies in sentence structure and context.
Expressing the Superlative
The most common superlative structure is:
الأَفْعَل + [definite noun] or أَفْعَل + [indefinite noun in genitive]
Examples:
هَذَا هُوَ الْأَكْبَرُ
Hādhā huwa al-akbaru
This is the biggest one.هِيَ أَجْمَلُ فَتَاةٍ
Hiya ajmalu fatātin
She is the most beautiful girl.هُوَ أَذْكَى طَالِبٍ فِي الْفَصْلِ
Huwa adhkā ṭālibin fī al-faṣli
He is the smartest student in the class.
In the second and third examples, the superlative (ajmalu, adhkā) is followed by an indefinite singular noun in the genitive — a classic superlative construction in Arabic.
Common Patterns and Exceptions
Colors and Physical Defects: The أَفْعَل/فَعْلَاء Pattern
Colors and adjectives describing physical traits follow a special pattern:
- Masculine: أَفْعَل (afʿal)
- Feminine: فَعْلَاء (faʿlāʾ)
- Plural (non-human): فُعْل (fuʿl)
| Masculine | Feminine | Plural | Meaning |
|---|---|---|---|
| أَحْمَر (aḥmar) | حَمْرَاء (ḥamrāʾ) | حُمْر (ḥumr) | red |
| أَبْيَض (abyaḍ) | بَيْضَاء (bayḍāʾ) | بِيض (bīḍ) | white |
| أَسْوَد (aswad) | سَوْدَاء (sawdāʾ) | سُود (sūd) | black |
| أَخْضَر (akhḍar) | خَضْرَاء (khaḍrāʾ) | خُضْر (khuḍr) | green |
| أَزْرَق (azraq) | زَرْقَاء (zarqāʾ) | زُرْق (zurq) | blue |
Examples:
- سَيَّارَةٌ حَمْرَاءُ (sayyāratun ḥamrāʾu) — a red car
- عَيْنَانِ زَرْقَاوَانِ (ʿaynāni zarqāwāni) — two blue eyes
Adjectives Derived from Nouns (Nisba Adjectives)
Arabic can create adjectives from nouns by adding the suffix ـِيّ (-iyy) for masculine or ـِيَّة (-iyya) for feminine. These are called nisba adjectives:
- عَرَبِيّ (ʿArabiyy) — Arab/Arabic (masculine)
- عَرَبِيَّة (ʿArabiyya) — Arab/Arabic (feminine)
- مِصْرِيّ (Miṣriyy) — Egyptian (masculine)
- إِسْلَامِيّ (Islāmiyy) — Islamic
You'll encounter many of these in everyday Arabic, especially for nationalities and origins.
Quick Reference: Adjective Agreement Summary
Here is a handy summary of all agreement rules for Arabic adjectives:
| Category | Rule |
|---|---|
| Gender | Masculine noun → masculine adjective; Feminine noun → add ة |
| Definiteness | Definite noun → adjective takes الـ |
| Singular human | Adjective matches gender (masc/fem singular) |
| Dual human | Adjective takes dual ending |
| Plural human (masc) | Sound masculine plural (-ūn/-īn) |
| Plural human (fem) | Sound feminine plural (-āt) |
| Plural non-human | Always use feminine singular adjective |
| Placement | Adjective comes after the noun |
| Comparative | Use أَفْعَل + مِنْ (does not change for gender) |
| Superlative | Use الأَفْعَل or أَفْعَل + indefinite genitive noun |
Practice Examples
Let's put it all together with some full sentences:
- الْوَلَدُ الطَّوِيلُ (al-waladu al-ṭawīlu) — the tall boy
- الْبِنْتُ الطَّوِيلَةُ (al-bintu al-ṭawīlatu) — the tall girl
- أَوْلَادٌ طِوَالٌ (awlādun ṭiwālun) — tall boys (human plural, broken plural adjective)
- أَشْجَارٌ طَوِيلَةٌ (ashjārun ṭawīlatun) — tall trees (non-human plural → fem. singular adjective)
- هَذِهِ الْمَدِينَةُ أَكْبَرُ مِنْ تِلْكَ — This city is bigger than that one.
- هِيَ أَجْمَلُ امْرَأَةٍ رَأَيْتُهَا — She is the most beautiful woman I have seen.

Tips for Mastering Arabic Adjectives
1. Learn adjectives in pairs
Study masculine and feminine forms together (كَبِير / كَبِيرَة) from the start rather than memorizing them separately.
2. Remember the non-human plural rule
This is the rule that trips up most learners. Drill it with many examples: cars, books, houses, animals — all take feminine singular adjectives in the plural.
3. Practice definiteness contrast
Make sentence pairs to feel the difference:
- بَيْتٌ كَبِيرٌ = a big house
- الْبَيْتُ الْكَبِيرُ = the big house
- الْبَيْتُ كَبِيرٌ = The house is big.
4. Use the أَفْعَل pattern actively
Once you know the 3-letter root of an adjective, you can almost always form the comparative. Practice this with adjectives you already know.
5. Immerse in authentic Arabic
Readings, videos, and conversations expose you to adjectives in natural context. Check out our strategies in How to Learn Arabic Fast: 10 Proven Strategies.
Conclusion
Arabic adjectives follow a beautifully systematic set of rules. Once you internalize gender and number agreement, the definite article requirement, post-noun placement, and the elegant أَفْعَل comparative/superlative pattern, you'll find that Arabic adjectives become one of the more predictable — and rewarding — parts of the language.
The key is consistent practice. Start with common adjectives from our Arabic vocabulary listing, form sentences, and pay attention to how adjectives behave in the Arabic texts and conversations you encounter.
Arabic grammar builds on itself: solid knowledge of adjectives will support you as you explore more advanced structures. Keep building, keep practicing, and the language will open up in remarkable ways.
