Look at these examples. Can you spot the grammar pattern?

كِتابٌ كَبيرٌ

مَدرَسَةٌ جَديدَةٌ

A new school

الكِتابُ كَبيرٌ

The book is big

Pay attention to the highlighted parts. What do they have in common?

الصفات (Adjectives)

Arabic adjectives follow the noun and must agree in 4 properties: gender, number, definiteness, and case.

PatternExampleNote
Indef. masc.كِتابٌ كَبيرٌa big book
Def. masc.الكِتابُ الكَبيرُthe big book
Indef. fem.مَدرَسَةٌ كَبيرَةٌa big school
Def. fem.المَدرَسَةُ الكَبيرَةُthe big school

Key: If noun has ال, adjective ALSO takes ال. Feminine adjectives add ة. Adjective comes AFTER noun (opposite to English).

Forgetting to add ال to the adjective when the noun is definite (الكتاب كبير = predicate, not attribute!). 🇬🇧 English: English adjectives never change form — Arabic adjectives change for gender, definiteness, and case. 🇩🇪 German: German adjective declension is similar in complexity, but Arabic's definiteness agreement (both noun+adj get ال) is distinctive.

Common Error Patterns

Mismatching definiteness between noun and adjective

الكتاب الكبير (both ال) = the big book; الكتاب كبير (only noun) = the book IS big

Not matching adjective gender to noun

Feminine nouns need feminine adjective: مدرسة كبيرة (not كبير)

كِتابٌ كَبيرٌ

A big book

Indefinite: both noun and adjective have tanwin. No ال on either.

الكِتابُ الكَبيرُ

The big book

Definite: BOTH noun and adjective take ال. This is attributive (not predicate).

مَدرَسَةٌ جَديدَةٌ

A new school

مدرسة is feminine → adjective also feminine: جديد → جديدة (add tā marbūṭa).

الكِتابُ كَبيرٌ

The book is big

Predicate: noun has ال but adjective does NOT → this is a sentence (the book IS big).
