The previous lesson used مُوسَىٰ. Its final alif maqṣūra does not visibly carry ḍamma, fatḥa, or kasra, so its case ending is estimated.
This lesson's زَيْدٌ، دَلْوٌ، ظَبْيٌ، رِجَالٌ show their case signs on the final letter. Their case marking is visible.
Principle
A final wāw or yāʾ does not automatically make every case ending estimated. The book explicitly classifies دَلْو and ظَبْي as treated like sound-final nouns.
