Al-muqaddimah Al-ajurrumiyyah [on the Science of Arabic Grammar]
The Chapter on the MUNĀDĀ
The Munādā is of five types:
Mufrad ‘Alam (singular proper noun)
Nakirah Maqṣūdah (intended indefinite noun)
Nakirah Ghayr Maqṣūdah (unintended indefinite noun)
Muḍāf (annexed noun)
Mushabbahah bi al-Muḍāf (what resembles the annexed noun)
As for the Mufrad ‘Alam and the Nakirah Maqṣūdah, they are Mabniyy (indeclinable with or built) on the Ḍammah without Tanwīn, like:
يازيدُ ويارجلُ (OZayd and OMan )[^83]
The remaining three are Manṣūb and nothing else[^84] .
