Structure and Role of Grammatical Subjects in Old Javanese

Historically, Old Javanese (OJ) language has been considered a dialect of the past and was developed rapidly from the IX - XV centuries. At that time, it was believed to be the language of communication and instruction for state administration. Although the language has evolved over the ages, it turns out that it has inherited several others. Therefore, OJ is suitable as a material for linguistic studies, and judging from its internal structure, it has many structural variations in forming its clauses. The grammatical subject should be described in detail and properly studied. The result shows that tentatively, the grammatical subjects in OJ can have different roles. By applying linguistic principles, this approach serves as a study model.
