Introduction
Part 1 of this lesson covered the three primary declension types — munsarif, ghayru munsarif, and mabni — which together account for about 100% of the Arabic words you will encounter at the level of individual nouns. But there is an important further distinction to make: most of those types express i'raab through a change in the vowel sign (haraka) at the end of the word. However, a number of important and frequently-used word types express their i'raab through a combination of letters and vowels — not a haraka alone.
Part 2 zooms out to give you the complete picture of all the ways i'raab is expressed, including the special cases of duals, sound plurals, and the famous five special nouns. The lesson also ends with a crucial warning about a common error: assuming that the final haraka on a word IS the i'raab. It is not — the category must always be considered first.
Finally, this lesson gives you the full roadmap of roles: 8 reasons for raf', 12 for nasb, and 2 for jarr — so you know exactly where the course is heading.
The Concept
### How i'raab is expressed — two mechanisms
The primary ways of expressing i'raab divide into two broad mechanisms:
Mechanism 1 — Haraka (vowel sign) at the end: Used by munsarif, ghayru munsarif e.g. مُسْلِمٌ / مُسْلِمًا / مُسْلِمٍ Mechanism 2 — Letter + vowel combination (suffix): Used by duals, sound plurals, and five special nouns e.g. مُسْلِمَانِ / مُسْلِمَيْنِ / مُسْلِمَيْنِ
### Special Category 1: Duals (مُثَنَّى)
The dual expresses i'raab through letter suffixes, not a single haraka:
رَفْع: ـَانِ — مُسْلِمَانِ، مُسْلِمَتَانِ نَصْب: ـَيْنِ — مُسْلِمَيْنِ، مُسْلِمَتَيْنِ جَرّ: ـَيْنِ — مُسْلِمَيْنِ، مُسْلِمَتَيْنِ
Nasb and jarr are the same for duals. The masculine and feminine dual differ only by the presence of تَاء مَرْبُوطَة in the feminine.
### Special Category 2: Sound Masculine Plural (جَمْعُ الْمُذَكَّرِ السَّالِمُ)
رَفْع: ـُونَ — مُسْلِمُونَ نَصْب: ـِينَ — مُسْلِمِينَ جَرّ: ـِينَ — مُسْلِمِينَ
Again, nasb and jarr share the same ending.
### Special Category 3: Sound Feminine Plural (جَمْعُ الْمُؤَنَّثِ السَّالِمُ)
رَفْع: ـَاتٌ — مُسْلِمَاتٌ نَصْب: ـَاتٍ — مُسْلِمَاتٍ جَرّ: ـَاتٍ — مُسْلِمَاتٍ
For the sound feminine plural, the nasb and jarr are the same (ـَاتٍ). This is one reason the Muslim pronoun table from Lesson 4 is so important — memorising it gives you mastery over all these plurals at once.
### Special Category 4: Manquus (مَنْقُوصٌ)
These are nouns with a kasra + ya at the end (e.g. قَاضٍ — a judge, وَادٍ — a valley). The ya disappears in raf' and jarr indefinite, but reappears in nasb:
رَفْع (indefinite): قَاضٍ (ya hidden) نَصْب: قَاضِيًا (ya visible, fatha returns) جَرّ (indefinite): قَاضٍ (ya hidden)
When الـ is added, the ya is always visible: الْقَاضِي (raf'), الْقَاضِيَ (nasb), الْقَاضِي (jarr).
### Special Category 5: Maqsuur (مَقْصُورٌ)
Nouns ending in alif that do not change their ending across all three i'raab:
عَصًا — عَصًا — عَصًا (a stick — same in all three) الْعَصَا — الْعَصَا — الْعَصَا (the stick — same in all three)
Similarly: دُنْيَا، بُشْرَى. This is due to phonetic constraints — the alif cannot take a haraka.
### Special Category 6: The Five Special Nouns (الْأَسْمَاءُ الْخَمْسَةُ)
These five nouns express i'raab using full letters — waw, alif, and ya — but only when they are mudaaf (in the possessive construct, studied in L10/L11):
رَفْع: وَاو — أَبُو حَامِدٍ (the father of Hamid) نَصْب: أَلِف — أَبَا حَامِدٍ جَرّ: يَاء — أَبِي حَامِدٍ
The five nouns: أَبٌ (father), أَخٌ (brother), حَمٌ (father-in-law), فُو (mouth, only in this construction), ذُو (possessor of). These are extremely common in hadith and the Quran.
### Critical warning — the haraka is NOT always the i'raab
Do NOT assume: kasra = jarr, dhamma = raf', fatha = nasb. The category MUST be checked first.
Examples that prove the rule:
| Word | Ending | Actual i'raab | Reason | |---|---|---|---| | مُسْلِمٍ | kasra | جَرّ | munsarif — haraka IS the i'raab here | | هَذِهِ | kasra | could be any | mabni — always ends in kasra | | مُسْلِمَانِ | kasra (on نِ) | رَفْع | dual raf' ends in ـَانِ | | مَسَاجِدَ | fatha | could be جَرّ | ghayru munsarif — fatha in jarr | | قَاضٍ | kasra + no ya | رَفْع or جَرّ | manquus — same in both |

Quranic Evidence
Summary
- I'raab can be expressed by a haraka (munsarif, ghayru munsarif) or by letter suffixes (duals, sound plurals, five special nouns).
- Duals use ـَانِ for raf' and ـَيْنِ for nasb/jarr. Sound masculine plurals use ـُونَ for raf' and ـِينَ for nasb/jarr. Sound feminine plurals use ـَاتٌ for raf' and ـَاتٍ for nasb/jarr.
- Manquus nouns (e.g. قَاضٍ) lose their ya in indefinite raf' and jarr. Maqsuur nouns (e.g. دُنْيَا) do not change at all.
- The five special nouns use waw (raf'), alif (nasb), and ya (jarr) as full letters — but only when in the possessive construct.
- Never assume the final haraka is the i'raab. Always identify the category first, then apply the appropriate rule.
- There are 8 reasons for raf', 12 for nasb, and only 2 for jarr — after prepositions or in the possessive.
