فَصْلٌ فِي أَصْنَافِ إِعْرَابِ الِاسْمِ: وَهِيَ تِسْعَةُ أَصْنَافٍ: الْأَوَّلُ: أَنْ يَكُونَ الرَّفْعُ بِالضَّمَّةِ، وَالنَّصْبُ بِالْفَتْحَةِ، وَالْجَرُّ بِالْكَسْرَةِ.
Translation: A section on the classes of noun case-marking. There are nine classes. In the first, the nominative takes ḍamma, the accusative takes fatḥa, and the genitive takes kasra.
This lesson covers only the first of the nine classes. We will study the other classes in the book's order in later levels.
