The human category nouns
In Modern Standard Arabic (MSA) there are two sentence types: the verbal sentence and the nominal sentence. Each type of sentence consists of two parts. Arab grammarians differentiate between the subject of a verbal sentence and the subject of nominal sentences is given in Arabic terms. The important difference between the verbal and nominal sentence is the position of the subject is that the subject never comes before the verb in a verbal sentence and the subject most often comes before the predicate in a nominal sentence. In its most basic form, a verbal clause consists of a verb and an implied subject indicated by an embedded subject marker. If necessary, an explicit standalone subject follows the verb and its embedded subject marker. No Arabic verb exists without a subject. Thus any instance of a verb marks a verbal clause. The subject of a verb is either embedded, or else it follows the verb as an overt subject.
