Murakkab — Compound Phrases
A murakkab is a phrase made of two or more words that together form a single meaning unit. Arabic has three main types, and understanding them is essential for parsing Quranic sentences correctly.
1. Murakkab Idaafi (المركّب الإضافي) — Possessive Compound
The most common type in the Quran. Two nouns are placed together where the second noun "possesses" or specifies the first. The first noun (mudaf) loses its tanwin, and the second noun (mudaf ilayhi) is always in the jarr case.
Rule
Mudaf (مُضاف) — no "al", no tanwin + Mudaf Ilayhi (مُضاف إليه) — always majrur (jarr case)
Quranic Examples
بِسْمِ اللَّهِ
bismi-llahi — In the name of Allah
اسم is mudaf (no tanwin), الله is mudaf ilayhi (jarr)
كِتَابُ اللَّهِ
kitabu-llahi — The book of Allah
كتاب has no tanwin (it's mudaf), الله is in jarr
يَوْمِ الدِّينِ
yawmi-d-dini — Day of Judgment
يوم (mudaf) + الدين (mudaf ilayhi, jarr)
2. Murakkab Wasfi (المركّب الوصفي) — Descriptive Compound
A noun followed by an adjective (or participle) that describes it. In Arabic, the adjective must match the noun in four things: gender, number, definiteness, and case (i'rab).
Quranic Examples
صِرَاطٍ مُّسْتَقِيمٍ
a straight path
Both are indefinite (tanwin), both in jarr — agreement!
الرَّحْمَنِ الرَّحِيمِ
The Most Gracious, The Most Merciful
Both definite (al-), both in jarr — two adjectives describing Allah
عَذَابٌ عَظِيمٌ
a great punishment
Both indefinite, both in raf' — full agreement
How to tell idaafi from wasfi: In idaafi, the first word has no "al" and no tanwin. In wasfi, both words agree in definiteness — both have "al" or both have tanwin.
3. Murakkab Mazji (المركّب المزجي) — Blended Compound
Two words fused into a single proper noun. This is rare in Quranic Arabic but appears in some proper names. The two parts lose their individual i'rab and are treated as one indeclinable (mabni) word.
Examples from classical Arabic: بَعْلَبَكّ (Baalbek), حَضْرَمَوْت (Hadramawt). These compound names function as single nouns.
Key Takeaways
- 1. Idaafi (possessive) is the most important compound type — the second noun is always in jarr.
- 2. Wasfi (descriptive) requires the adjective to match the noun in gender, number, definiteness, and case.
- 3. The key test: if the first word has no "al" and no tanwin, it's probably idaafi.
