فَـ«عَبْدُ اللَّهِ» مُنْصَرِفٌ، وَ«مَعْدِيكَرِب» غَيْرُ مُنْصَرِفٍ، وَ«شَابَ قَرْنَاهَا» مَبْنِيٌّ.
Translation: ʿAbd Allāh is fully declinable, Maʿdīkarib is diptote, and Shāba Qarnāhā is indeclinable.
These three different outcomes are the point of the lesson: not every compound is declined in the same way.
