A particle "-nya", which is recently shown, has a clitic nature. Its function is expanded in a variety of morphological or syntactic forms. In the grammar books of Dutch and English scholars, they explain that the particle "-nya" is used as the abbreviation of the third person singular pronoun, or that it has a function of nominalization in adjectives or intransitive verbs and a function of stress word. However, in a modern Indonesian based on Melayu, we have seen that its function and role of the particle "-nya" expand and develop the following forms with respect to morphological features: 1. The particle "-nya" represents the third person singular. It is also used as the plural pronoun which represents a singular and a plural numbers of people, animals, or things. 2. It is used as a nominal suffix of adjectives and verbs (intransitive and transitive), and makes noun phrases with combination of transitive verbs. 3. It is used as a suffix with adverbial function. 4. It is used as a determiner or a demonstrative. 5. It makes a sentence of possession relationship, which has a clitic nature. 6. It has a function of allowing double subject constructions or topik-komen. This study has shown that languages have changed and developed in a steady manner. In Indonesian, which is structurally different from Korean, double subject constructions are only explained in "topik-komen" structures, and now they are used as the same structures with the particle "-nya" function.
