Nominal sentence

Up until now I have been learning words, phrases and vowels. Today I am beginning to learn about sentences. The first type of sentence I am learning is called nominal sentence, or in Arabic is called الْجُملَةُ الْاِسْمِيَّةُ al jumlatu al ismiiyatu. Here are the rules of nominal sentence:

1. It always begins with a noun or pronoun.
2. It has two parts which is the subject called مُبتَدَأ mubtada and the predicate called خَبَر khabar.
3. The مُبتَدَأ must always be a noun or pronoun.
4. Generally, both the مُبتَدَأ andخَبَر are in the nominative case, that is the last huruf is a dhammah  ُor dhammatain   ٌ.

Examples of nominal sentences
The word colored in green is the مُبتَدَأ while the rest of the sentence is theخَبَر.
