Some Vocatives Are Already Definite

The Vocative and Definiteness

A vocative may already be definite before it is called.

- Proper name: يَا إِبْرَاهِيمُ
- A noun introduced through أَيُّهَا or أَيَّتُهَا: يَا أَيُّهَا النَّبِيُّ / يَا أَيَّتُهَا الْعِيرُ
- Definite idafah: يَا نِسَاءَ النَّبِيِّ

These expressions do not become definite merely because يَا was added.
