Adjective Agreement (Na't and Man'ut)

Understand how adjectives agree with nouns in gender, number, case, and definiteness, and identify adjective-noun pairs in the Quran.

Introduction

You’ve mastered the three-case system and understand sentence structure (nominal vs verbal). Now we turn to one of Arabic’s most elegant grammatical features: how adjectives mirror their nouns in every grammatical detail. This precision creates unambiguous, beautiful descriptions throughout the Quran.

Al-Fatiha 1:6

Word— touch a word —

ihdinā ṣ-ṣirāṭa l-mustaqīma

Guide us to the straight path

— Al-Fatiha 1:6

Notice how ٱلْمُسْتَقِيمَ (al-mustaqīma) “the straight” perfectly mirrors ٱلصِّرَٰطَ (aṣ-ṣirāṭa) “the path” in FOUR ways: both are definite (with ال), masculine, singular, and accusative (with fatha). This is the four-part agreement that makes Arabic adjectives work.

In this lesson, you will:

  • Understand the four-part agreement rule: gender, number, case, and definiteness
  • Identify adjectives (naʿt / نَعْتٌ) and their described nouns (manʿūt / مَنْعُوتٌ)
  • Distinguish between adjectives (which follow nouns) and predicates (which complete nominal sentences)
  • Analyze adjective-noun pairs in Quranic verses using i’rab analysis

Connection to previous learning: You learned subject-predicate agreement in L2.02 and understand the three cases from L2.04-06. Now you’ll apply this knowledge to adjective-noun relationships — a different grammatical pattern with stricter agreement rules.

Key distinction: An adjective DESCRIBES a noun (ٱلصِّرَٰطَ ٱلْمُسْتَقِيمَ “the straight path”), while a predicate COMPLETES a sentence (ٱلصِّرَٰطُ مُسْتَقِيمٌ “the path is straight”). Same Arabic words, completely different grammatical relationships!

Understanding Adjective Agreement

Plain English first: An adjective is a describing word that modifies a noun. In English, adjectives come BEFORE nouns (“the big house”) and don’t change form. In Arabic, adjectives come AFTER nouns and must match them in four specific ways.

English analogy: Think of adjectives like a mirror reflecting the noun. French and Spanish speakers will recognize this — “la casa grande” (the house big), where “grande” agrees with “casa” in gender. Arabic takes this further: adjectives must match in gender, number, case, AND definiteness.

Now the Arabic terminology: The adjective (naʿt / نَعْتٌ) — literally “description” — modifies the described noun (manʿūt / مَنْعُوتٌ). Together they form an adjective-noun pair.

The Four-Part Agreement Rule

Every Arabic adjective MUST agree with its noun in exactly FOUR properties:

PropertyAgreement RuleExample NounExample Adjective
1. GenderMasculine → masculine
Feminine → feminine
ٱلرَّجُلُ (the man)
ٱلْمَرْأَةُ (the woman)
ٱلْكَبِيرُ (the big [masc.])
ٱلْكَبِيرَةُ (the big [fem.])
2. NumberSingular → singular
Dual → dual
Plural → plural
ٱلْكِتَابُ (the book)
ٱلْكِتَابَانِ (the two books)
ٱلْكُتُبُ (the books)
ٱلْجَدِيدُ (the new [sing.])
ٱلْجَدِيدَانِ (the new [dual])
ٱلْجُدُدُ (the new [plural])
3. CaseNominative → nominative
Accusative → accusative
Genitive → genitive
ٱلْبَيْتُ (the house [nom.])
ٱلْبَيْتَ (the house [acc.])
ٱلْبَيْتِ (the house [gen.])
ٱلْكَبِيرُ (the big [nom.])
ٱلْكَبِيرَ (the big [acc.])
ٱلْكَبِيرِ (the big [gen.])
4. DefinitenessDefinite → definite
Indefinite → indefinite
ٱلْكِتَابُ (THE book)
كِتَابٌ (A book)
ٱلْجَدِيدُ (THE new)
جَدِيدٌ (A new)

The pattern: Adjective mirrors ALL four properties of the noun it describes.

Example showing all four agreements:

  • Noun: ٱلصِّرَٰطَ (aṣ-ṣirāṭa) — definite, masculine, singular, accusative
  • Adjective: ٱلْمُسْتَقِيمَ (al-mustaqīma) — definite, masculine, singular, accusative
  • All four match! ✓ Gender ✓ Number ✓ Case ✓ Definiteness

Word Order: Noun FIRST, Then Adjective

Critical difference from English:

  • English: ADJECTIVE + noun → “the straight path”
  • Arabic: NOUN + adjective → “ٱلصِّرَٰطَ ٱلْمُسْتَقِيمَ” (the path, the straight)

The rule: In Arabic, the noun ALWAYS comes first, followed by the adjective.

Wrong order:

  • ٱلْمُسْتَقِيمَ ٱلصِّرَٰطَ (the straight the path) — grammatically incorrect!

Correct order:

  • ٱلصِّرَٰطَ ٱلْمُسْتَقِيمَ (the path the straight) — adjective follows noun

Exception to be aware of: When two definite nouns appear together (both with ال), they could be either:

  1. Adjective-noun pair (both describe the same thing)
  2. Iḍāfah (possessive) construction (X OF Y relationship)

Context determines which! We’ll see examples of this distinction below.

Adjective vs. Predicate: The Key Distinction

This is crucial: the SAME Arabic word can function as either an adjective OR a predicate, depending on sentence structure.

As Adjective (naʿt):

  • ٱلصِّرَٰطَ ٱلْمُسْتَقِيمَ (aṣ-ṣirāṭa l-mustaqīma) — “the straight path”
  • Function: ٱلْمُسْتَقِيمَ is an ADJECTIVE describing ٱلصِّرَٰطَ
  • Structure: One phrase (noun + adjective)
  • Meaning: A modified noun

As Predicate (khabar):

  • ٱلصِّرَٰطُ مُسْتَقِيمٌ (aṣ-ṣirāṭu mustaqīmun) — “the path is straight”
  • Function: مُسْتَقِيمٌ is a PREDICATE completing a nominal sentence
  • Structure: Complete sentence (subject + predicate)
  • Meaning: A statement about the subject

How to tell the difference:

  1. Check definiteness: If BOTH have ال (definite), it’s an adjective. If one is definite and one indefinite, it’s likely a predicate.
  2. Check meaning: Does it describe (adjective) or make a statement (predicate)?
  3. Check structure: Is it a phrase (adjective) or a complete thought (predicate)?

Examples from the Quran

Let’s examine adjective-noun pairs from Surah Al-Fatiha, analyzing the four-part agreement in each case.

Example 1: Definite Masculine Singular Accusative

Al-Fatiha 1:6

Word— touch a word —
Meaning
Transliteration

ihdinā ṣ-ṣirāṭa l-mustaqīma

Guide us to the straight path

— Al-Fatiha 1:6

Complete grammatical analysis (iʿrāb):

  • ٱهْدِنَا (ihdinā) — Command verb with attached pronoun — “guide us”

    • ٱهْدِ (ihdi): Imperative verb “guide”
    • نَا (nā): Attached object pronoun “us” (accusative)
    • Function: Command addressing Allah
    • Hidden subject: أَنْتَ (You — Allah) in nominative
  • ٱلصِّرَٰطَ (aṣ-ṣirāṭa) — Direct object (manʿūt) — “the path”

    • Function: Direct object of the verb ٱهْدِنَا
    • Case marker: Accusative with fatha (ـَ)
    • Reason: Direct objects take accusative case
    • Described noun (manʿūt): The noun being modified
    • Properties: Definite (ال), masculine, singular, accusative
  • ٱلْمُسْتَقِيمَ (al-mustaqīma) — Adjective (naʿt) — “the straight”

    • Function: Adjective describing ٱلصِّرَٰطَ
    • Case marker: Accusative with fatha (ـَ)
    • Reason: Adjectives match their nouns in ALL four properties
    • Agreement check:
      • ✓ Definiteness: Both have ال (definite)
      • ✓ Gender: Both masculine
      • ✓ Number: Both singular
      • ✓ Case: Both accusative (ـَ)

Word-by-word morphological breakdown of ٱلْمُسْتَقِيمَ:

ٱلْمُسْتَقِيمَ (al-mustaqīma):

  • Root: ق-و-م (qāf-wāw-mīm), meaning “to stand, be upright, straighten”
  • Form: Active participle from Form X (اِسْتَفْعَلَ istafʿala pattern)
  • Meaning: “The one that is straight, the upright, the established”
  • Definiteness: Definite with ال article
  • Gender: Masculine (no tāʾ marbūṭah)
  • Number: Singular
  • Case: Accusative (matches ٱلصِّرَٰطَ)

Structural insight: The phrase ٱلصِّرَٰطَ ٱلْمُسْتَقِيمَ forms a tight adjective-noun unit. You can’t separate them — together they mean “the straight path” as a single concept.

Example 2: Definite Masculine Singular Genitive

Al-Fatiha 1:7

Word— touch a word —

Transliteration

ṣirāṭa lladhīna anʿamta ʿalayhim ghayri l-maghḍūbi ʿalayhim wa lā ḍ-ḍāllīna

The path of those upon whom You have bestowed favor, not of those who have earned anger nor of those who are astray

— Al-Fatiha 1:7

Complete grammatical analysis (iʿrāb) — focusing on adjective:

  • غَيْرِ (ghayri) — Exception/negative attribute — “not of”

    • Function: Genitive noun meaning “other than, not”
    • Case marker: Genitive with kasra (ـِ)
    • Reason: Appositive/descriptive addition to the path
    • First part of iḍāfah
  • ٱلْمَغْضُوبِ (al-maghḍūbi) — Passive participle (second in iḍāfah) — “those angered”

    • Function: Second term in iḍāfah (“other than THE angered-upon”)
    • Case marker: Genitive with kasra (ـِ)
    • Reason: Second noun in possessive construction
    • Form: Passive participle from Form I
  • عَلَيْهِمْ (ʿalayhim) — Prepositional phrase — “upon them”

    • Function: Completes the passive participle (angered-upon THEM)
    • Structure: عَلَىْٰ (preposition “upon”) + هِمْ (pronoun “them”)

Advanced note on participles as adjectives:

The word ٱلْمَغْضُوبِ (al-maghḍūbi) “the angered-upon ones” is a passive participle functioning as a noun/adjective. It describes a state or characteristic. While it’s technically part of an iḍāfah here, passive and active participles frequently serve as adjectives in Arabic.

Example 3: Multiple Attributes of Allah

Al-Fatiha 1:1

Word— touch a word —
Meaning
Transliteration

bismi llāhi r-raḥmāni r-raḥīmi

In the name of Allah, the Most Gracious, the Most Merciful

— Al-Fatiha 1:1

Complete grammatical analysis (iʿrāb):

  • بِسْمِ (bismi) — Prepositional phrase — “in the name of”

    • بِ (bi): Preposition “in/with/by”
    • ٱسْمِ (ismi): Genitive with kasra (ـِ) after preposition
    • First part of iḍāfah
  • ٱللَّهِ (allāhi) — Possessive (manʿūt for adjectives) — “Allah”

    • Function: Second term in iḍāfah (“name OF Allah”)
    • Case marker: Genitive with kasra (ـِ)
    • Reason: Second noun in possessive construction
    • Described noun: The noun being modified by following adjectives
  • ٱلرَّحْمَٰنِ (ar-raḥmāni) — First adjective (naʿt) — “the Most Gracious”

    • Function: Adjective describing ٱللَّهِ
    • Case marker: Genitive with kasra (ـِ)
    • Reason: Adjectives match their nouns in case
    • Agreement check with ٱللَّهِ:
      • ✓ Definiteness: Both definite (proper name / ال)
      • ✓ Gender: Both masculine
      • ✓ Number: Both singular
      • ✓ Case: Both genitive (ـِ)
  • ٱلرَّحِيمِ (ar-raḥīmi) — Second adjective (naʿt) — “the Most Merciful”

    • Function: Second adjective describing ٱللَّهِ
    • Case marker: Genitive with kasra (ـِ)
    • Reason: Adjectives match their nouns in case
    • Agreement check with ٱللَّهِ:
      • ✓ All four properties match (same as first adjective)

Multiple adjectives pattern: You can stack multiple adjectives describing the same noun. Each adjective independently agrees with the noun in all four properties. Here, both ٱلرَّحْمَٰنِ and ٱلرَّحِيمِ describe ٱللَّهِ.

Word-by-word morphological breakdown:

ٱلرَّحْمَٰنِ (ar-raḥmāni):

  • Root: ر-ح-م (rāʾ-ḥāʾ-mīm), meaning “to have mercy, show compassion”
  • Form: Intensive form (فَعْلَانُ faʿlānu pattern) emphasizing abundance
  • Meaning: “The Most Gracious” (intensive mercy to ALL creation)
  • Case: Genitive matching ٱللَّهِ

ٱلرَّحِيمِ (ar-raḥīmi):

  • Root: ر-ح-م (same root as ٱلرَّحْمَٰنِ)
  • Form: Active participle (فَعِيلٌ faʿīlun pattern)
  • Meaning: “The Most Merciful” (continuous mercy, especially to believers)
  • Case: Genitive matching ٱللَّهِ

Theological precision through grammar: Both attributes share the same root (ر-ح-م mercy) but use different patterns to convey distinct theological nuances. Grammar enables precision in describing Divine attributes.

Example 4: Adjective vs. Predicate Contrast

Let’s compare two similar-looking structures to understand the adjective-predicate distinction:

Structure 1: Adjective (naʿt)

Al-Fatiha 1:6

Word— touch a word —
Meaning
Transliteration

aṣ-ṣirāṭa l-mustaqīma

the straight path

— Al-Fatiha 1:6

Analysis:

  • Both words definite (both have ال)
  • Both accusative (both end with fatha ـَ)
  • ٱلْمُسْتَقِيمَ is an ADJECTIVE modifying ٱلصِّرَٰطَ
  • Structure: Noun + Adjective (a phrase, not a sentence)
  • Meaning: “the straight path” (one concept)

Structure 2: Predicate (khabar) — hypothetical contrast

If we restructured this as a nominal sentence:

ٱلصِّرَٰطُ مُسْتَقِيمٌ (aṣ-ṣirāṭu mustaqīmun) — “The path is straight”

Analysis:

  • First word definite (ٱلصِّرَٰطُ with ال)
  • Second word indefinite (مُسْتَقِيمٌ no ال, has tanwīn ـٌ)
  • Different cases: nominative + nominative
  • مُسْتَقِيمٌ is a PREDICATE completing a sentence
  • Structure: Subject + Predicate (a complete sentence)
  • Meaning: “The path is straight” (a statement)

How to tell them apart:

FeatureAdjective (Naʿt)Predicate (Khabar)
DefinitenessBoth definite OR both indefiniteUsually: definite noun + indefinite predicate
CaseBoth match the sentence functionBoth nominative (in basic nominal sentences)
StructurePhrase (part of larger sentence)Complete sentence
MeaningModifies/describesMakes a statement
PositionAlways follows noun directlySeparated from subject (can have words between)

Example showing the difference:

  1. Adjective: رَأَيْتُ ٱلرَّجُلَ ٱلْكَبِيرَ (raʾaytu r-rajula l-kabīra)

    • “I saw THE BIG man”
    • Both definite (ال + ال)
    • Both accusative (ـَ + ـَ)
    • ٱلْكَبِيرَ is adjective
  2. Predicate: ٱلرَّجُلُ كَبِيرٌ (ar-rajulu kabīrun)

    • “The man IS big”
    • Definite + indefinite (ال + tanwīn)
    • Both nominative (ـُ + ـٌ)
    • كَبِيرٌ is predicate

Example 5: Feminine Adjective Agreement

Al-Fatiha 1:2

Word— touch a word —
Meaning
Transliteration

al-ḥamdu lillāhi rabbi l-ʿālamīna

All praise is for Allah, Lord of the worlds

— Al-Fatiha 1:2

While this verse doesn’t contain a feminine adjective example, let’s examine how feminine agreement works:

Feminine noun + feminine adjective pattern:

ٱلْمَرْأَةُ ٱلْكَرِيمَةُ (al-marʾatu l-karīmatu) — “the generous woman”

Agreement analysis:

  • ٱلْمَرْأَةُ (al-marʾatu): Noun

    • Definiteness: Definite (ال)
    • Gender: Feminine (inherent)
    • Number: Singular
    • Case: Nominative (ـُ)
  • ٱلْكَرِيمَةُ (al-karīmatu): Adjective

    • Definiteness: Definite (ال) ✓ matches
    • Gender: Feminine (tāʾ marbūṭah ة) ✓ matches
    • Number: Singular ✓ matches
    • Case: Nominative (ـُ) ✓ matches

Key marker: The tāʾ marbūṭah (ة) at the end of the adjective signals feminine gender agreement. If the noun is feminine, the adjective MUST have ة (with rare exceptions for inherently feminine words).

The Rule

Practice

Exercise 1: Identify the adjective-noun pair in this phrase and verify all four agreements: ٱلصِّرَٰطَ ٱلْمُسْتَقِيمَ (aṣ-ṣirāṭa l-mustaqīma) — 'the straight path' [Al-Fatiha 1:6]

Exercise 2: Explain the difference between these two phrases: (a) ٱلْكِتَابُ ٱلْجَدِيدُ and (b) ٱلْكِتَابُ جَدِيدٌ. Which is adjective, which is predicate?

Exercise 3: Add the correct adjective form of كَبِيرٌ (big) to each noun, ensuring all four agreements: (a) ٱلْبَيْتُ ___ (nominative), (b) رَأَيْتُ ٱلْبَيْتَ ___ (accusative), (c) فِى ٱلْبَيْتِ ___ (genitive)

Exercise 4: Advanced — Analyze this phrase from Al-Fatiha and identify which words are adjectives and which are predicates: بِسْمِ ٱللَّهِ ٱلرَّحْمَٰنِ ٱلرَّحِيمِ (bismi llāhi r-raḥmāni r-raḥīmi) — 'In the name of Allah, the Most Gracious, the Most Merciful'
