In Arabic, extended nouns (الاسم الممدود) are nouns that end in an Alif followed by a Hamza (ـاء). Many plural words for groups of people follow this pattern, such as the plurals for allies (حلفاء), enemies (أعداء), and leaders (زعماء).
The Shifting Hamza
When you attach a pronoun suffix (like ـنا or ـه) to these nouns, the Hamza moves to the middle of the word. Arabic spelling rules dictate that a middle Hamza must sit on a "seat" matching its vowel.
Because grammatical case dictates the final vowel of a noun, the seat of the Hamza physically changes based on the noun's role in the sentence!
Nominative Case: Hamza on Waw (ـؤُ)
When the noun is in the nominative case—for instance, when it is the subject performing the action—it takes a Damma vowel. The Damma requires the Hamza to sit on a Waw.
| Our allies founded a strong coalition. | أسس حلفاؤنا ائتلافا قويا.assasa hulafâ'unâ i'tilâfan qawiyyan. |
Accusative Case: Hamza on the Line (ـءَ)
When the noun is in the accusative case—such as when it is the direct object receiving the action, or when it directly follows particles like إن—it takes a Fatha vowel. The Fatha causes the Hamza to sit directly on the line.
| We observed our enemies in the new coalition. | راقبنا أعداءنا في الائتلاف الجديد.râqabnâ a'dâ'anâ fî al-i'tilâfi al-jadîdi |
| The minister said that our leaders sided with the new bloc. | قالت الوزيرة إن زعماءنا انحازوا إلى التكتل الجديد.qâlati al-wazîratu inna zu'amâ'anâ in'hâzû ilâ at-takattuli al-jadîd. |
Genitive Case: Hamza on Yaa (ـئِ)
When the noun is in the genitive case—most commonly because it follows a preposition or is the second part of a possessive construction—it takes a Kasra vowel. The Kasra requires the Hamza to sit on a dotless Yaa (often called a "tooth" or "chair").
| No one dominates our allies in this bloc. | لا أحد يهيمن على حلفائنا في هذا التكتل.lâ 'ahada yuhayminu 'alâ hulafâ'inâ fî hâdhâ at-takattuli |
Recognizing Case Through Spelling
Paying attention to the Hamza's seat is crucial when reading, as it instantly reveals who is doing the action and who is receiving it.
Notice the visual contrast in the following sentence between the nominative subject (حلفاؤه) and the accusative direct object (وزراءه):
| His allies opposed the decision, therefore the president opposed his ministers. | عارض حلفاؤه القرار، لذلك عارض الرئيس وزراءه.âraḍa ḥulafâ'uhu al-qarâra, lidhâlika âraḍa ar-ra'îsu wuzarâ'ahu |
