Arabic plural
Exercise where I have to rewrite sentences in the plural form:
أنظر إلى الربابة قديمة في المتحف الشعبيّ.
ننظر إلى الربابات قديمةٍ في المتاحف الشعبيةٍ.
Would anyone care to explain why 'popular' becomes female in the plural form?
Another thing I don't understand is that in my lessons I've been told that before an external plural form, the verb stays in the singular. In this sentence, the keys show the following:
.يزور معلّماً خزائراً
Plural:
يزورون معلّمين جزائرين
According to the lesson, the verb should remain the same. What am I missing?
Thank you in advance.
