This research sheds light on the phenomenon of derivation in Arabic morphology and discusses the opinions put forward by grammarians and linguists concerning its origin. The phenomenon has long been a subject of dispute. The research discusses the existing view on the origin and branch and proves that such view is incorrect. According to this research, the linguistic reality supports the claim that neither the verbal noun nor the verb is the origin of the derivatives. The research also displays various types of derivation in Arabic and explains the value each type has in enriching Arabic by providing the vocabulary and linguistic elements required to keep up with the times and adapt accordingly. The research concludes that derivatives originate from linguistic elements and the three consonants. The consonants themselves are meaningless but combining a tense gives them a specific meaning.
