Describing a Noun Through Something Attached To It

Level 5

The Causal Adjective (النعت السببي) is a sophisticated way to describe a noun through a related attribute. Instead of saying 'the beautiful garden,' you say 'the garden whose trees are beautiful.' It functions like a condensed relative clause.

How It Works

The النعت السببي (Al-Na't al-Sababi) is a hallmark of high-register Modern Standard Arabic. Unlike a True Adjective, which describes a noun directly, the Causal Adjective describes a noun (the man'ut) via a second noun (the sabab) that is connected to it by a possessive pronoun.

Grammatical Rules:

  • Agreement with the Preceding Noun: The adjective must match the first noun in Case and Definiteness.
  • Agreement with the Following Noun: The adjective must match the second noun in Gender.
  • Number Fixity: The adjective is always singular, even if the nouns it connects are dual or plural.
  • The Attached Pronoun: The pronoun attached to the second noun must match the first noun in gender and number.

Syntactic Function:
The adjective is usually a derivative like an Active Participle, Passive Participle, or Quality Adjective. The noun following it is grammatically the Subject (Fa'il) if the adjective is active, or the Pro-agent (Na'ib Fa'il) if the adjective is passive. This structure is more concise than using a Relative Pronoun clause.

Examples (4)

  1. هذا بيتٌ واسعةٌ غُرَفُهُ

    This is a house whose rooms are spacious.

    Word by Word: This house spacious rooms-its.

    'واسعة' (spacious) matches 'بيت' (house) in case (nominative) and indefiniteness, but matches 'غرف' (rooms) in gender (feminine).

  2. رأيتُ الولدَ المكسورةَ يدُهُ

    I saw the boy whose hand is broken.

    Word by Word: I saw the boy the broken hand-his.

    'المكسورة' matches 'الولد' in case (accusative) and definiteness, but matches 'يد' (hand) in gender (feminine).

  3. مررتُ برجلٍ كريمٍ أبوهُ

    I passed by a man whose father is generous.

    Word by Word: I passed by a man generous father-his.

    'كريم' matches 'رجل' in case (genitive) and matches 'أب' (father) in gender (masculine).

  4. هؤلاءِ طلابٌ ناجحٌ أخوهم

    These are students whose brother is successful.

    Word by Word: These students successful brother-their.

    Note that 'ناجح' remains singular even though 'طلاب' (students) is plural.

Common Mistakes

  • Making the adjective plural to match a plural first noun.

    هؤلاءِ رجالٌ كرامٌ آباؤهم
    هؤلاءِ رجالٌ كريمٌ آباؤهم

    The Causal Adjective must always remain singular, regardless of the number of the nouns it describes.

  • Matching the adjective's gender to the first noun instead of the second.

    رأيتُ البنتَ الناجحةَ أخوها
    رأيتُ البنتَ الناجحَ أخوها

    The adjective must match the gender of the noun that follows it (the brother), not the noun that precedes it (the girl).
