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.

ٱهْدِنَا guide us
ٱلصِّرَٰطَ the path
ٱلْمُسْتَقِيمَ the straight

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

ٱهْدِنَا guide us
ٱلصِّرَٰطَ the path
ٱلْمُسْتَقِيمَ the straight

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

صِرَٰطَ path of
ٱلَّذِينَ those who
أَنْعَمْتَ You bestowed favor
عَلَيْهِمْ upon them
غَيْرِ not of
ٱلْمَغْضُوبِ those angered
عَلَيْهِمْ upon them
وَلَا and not
ٱلضَّآلِّينَ the astray

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

بِسْمِ in the name of
ٱللَّهِ Allah
ٱلرَّحْمَٰنِ the Most Gracious
ٱلرَّحِيمِ the Most Merciful

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)

ٱلصِّرَٰطَ the path
ٱلْمُسْتَقِيمَ the straight

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

ٱلْحَمْدُ the praise
لِلَّهِ for Allah
رَبِّ Lord
ٱلْعَٰلَمِينَ the worlds

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'
