● A broken plural shows its grammatical case through tanwīn vowel marks, just like a singular noun:
○ nominative: two ḍammahs (ٌ) on the final letter, as in رِجَالٌ (many men).
○ accusative: two fatḥahs (ً) with an added alif, as in رِجَالًا.
○ genitive: two kasrahs (ٍ) beneath the final letter, as in رِجَالٍ.
● Note: A broken plural ending in round tāʾ, such as أَلْسِنَةٌ, does not take a final alif in the accusative.
