In Arabic, default kind of sentence is called a nominal sentence. It looks something like this:
- Ahmad is rich
- The masjid is big
- I am a Muslim
It has two parts–the mubtada (the subject — eg. Ahmad), and the khabr (the predicate–information about the mubtada — eg. rich, big, a Muslim).
What are the rules of grammar as they apply to the mubtada and the khabr? There are three:
- Match: The khabr must match the mubtada in number (eg. singular, plural) and in gender.
- Definite: The mubtada cannot be indefinite–it must be definite.
- Dumma: The mubtada must take dumma (single dumma, too, because it’s definite) — and, when dissecting complex sentences of any type, this is how you locate the mubtada!

Over my head~
But MashaAllah, thanks for sharing the knowledge.
the mubtada can be indefinit in some limited cases
please list them or this will not be complete
for example
mubtada can be nakirah(indefinit)if there was a dameer(pronoun)in the khabar that refres to it
and what else….?
