The research methode that was used is decriptive qualitative method. To gain the data the researchers used literature review in which the data gained from dictionary.Every morpheme can be classified as either free or bound. Bound morphemes can be further classified as derivational or inflectional. These categories are mutually exclusive, and as such, a given morpheme will belong to exactly one of them.
