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

جمع التكسير (Broken Plural)

Most Arabic nouns form plurals by changing the internal vowel pattern (not just adding a suffix). These are called broken plurals because the word's structure "breaks."

SingularPluralPattern
كِتاب (book)كُتُبفُعُل
طالِب (student)طُلّابفُعّال
مَدرَسَة (school)مَدارِسمَفاعِل
وَلَد (boy)أَولادأَفعال
بَيت (house)بُيوتفُعول

Key: Broken plurals must be memorized with each noun. Non-human plurals are treated as feminine singular for adjective agreement.

Trying to predict broken plural patterns instead of memorizing them; using plural adjectives with non-human plurals. 🇬🇧 English: English has a few irregular plurals (child→children) but Arabic's broken plurals are the norm, not the exception. 🇩🇪 German: German Umlaut plurals (Buch→Bücher) are the closest parallel to Arabic's internal vowel changes.

Common Error Patterns

Using wrong broken plural pattern

Broken plurals must be memorized: كتاب→كتب, طالب→طلاب, بيت→بيوت

Using plural adjective with non-human plural

Non-human plurals take fem. sing. adjective: كتب كثيرة (not كثيرون)

كُتُبٌ كَثيرَةٌ

Many books

كتاب → كُتُب (فُعُل pattern). Adjective كثيرة is fem. sing. for non-human plural.

الطُّلّابُ في الصَّفِّ

The students are in class

طالب → طُلّاب (فُعّال pattern). Human plural — used for male students.

المَدارِسُ قَريبَةٌ

The schools are nearby

مدرسة → مَدارِس (مَفاعِل pattern). قريبة = fem. sing. adjective for non-human plural.

أَولادٌ صِغارٌ

Small boys

ولد → أولاد (أفعال pattern). Human plural → adjective agrees: صغير → صغار.
