Describing a Noun Through Something Attached To It
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)
- 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).
- 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).
- 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).
- 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 آباؤهمهؤلاءِ رجالٌ كريمٌ آباؤهمThe 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 أخوهارأيتُ البنتَ الناجحَ أخوهاThe adjective must match the gender of the noun that follows it (the brother), not the noun that precedes it (the girl).
How It Connects
Learn This First
To understand the causal adjective (النعت السببي), you must first be comfortable with standard adjectives and how they match nouns. You also need to understand how possessive pronouns link nouns together and how gender agreement works between a quality and the specific person or thing it belongs to.
- Adjectives Follow the Noun
The learner must first understand the basic concept of a real adjective (النعت الحقيقي) and how it follows a noun before learning the more complex 'causal' adjective.
Level 1 - Possessive Endings on Nouns
The causal adjective pattern requires a noun that contains a possessive pronoun referring back to the original described noun (e.g., أبوه).
Level 1 - The Verb Agrees in Gender
The causal adjective matches the gender of the noun following it (the 'sabab'), which functions similarly to a subject-verb gender agreement rule.
Level 2
Related Patterns
- الذي / التيWhich and Who
Causal adjectives are often used as a more formal, concise alternative to relative clauses.
Level 3 - Lasting Qualities
This type of adjective is frequently used in the Causal Adjective construction to describe lasting qualities.
Level 4 - The Doer of the Verb
The noun following an active causal adjective is grammatically parsed as its subject (Fa'il).
Level 2 - The Subject of a Passive Verb
If the causal adjective is a passive participle, the following noun acts as the Na'ib Fa'il.
Level 3 - Matching the Article on Adjectives
The Causal Adjective still follows the rule of matching the first noun's definiteness.
