● In Arabic, when the subject (mubtadaʾ) is dual, referring to two, the predicate (khabar) must also be dual.
● In earlier lessons, we learned that the nominative (marfūʿ) form of the dual is shown by the ending "ـَانِ".
● Masculine dual example:
○ Zayd and Ḥāmid are righteous. -> زَيْدٌ وَحَامِدٌ صَالِحَانِ
■ Here, the subject contains two masculine nouns, so the predicate is also masculine dual: صَالِحَانِ.
● Feminine dual example:
○ Maryam and Zaynab are righteous. -> مَرْيَمُ وَزَيْنَبُ صَالِحَتَانِ
■ Here, the subject contains two feminine nouns, so the predicate is also feminine dual: صَالِحَتَانِ.
