The negotiation of epistemic and deontic rights in child-adult interactions in colloquial Jakartan Indonesian

Discourse markers can function to mark epistemic and deontic modality. This study aims to explore how children and adults apply the discourse marker deh to signal their epistemic and deontic rights. Previous studies only dealt with how the deontic aspect of deh is used in determining future actions. There is no discussion on how the speakers use epistemic and deontic rights in interactions even though both are interrelated. Furthermore, the previous studies only dealt with adults' language. The present study explores how epistemic and deontic rights are marked by children and adults with deh by conducting a discourse analysis. The data were obtained from the CHILDES (Child Language Data Exchange System). Speakers' neglect of information offered to them reveals that they instead make decisions based on the knowledge they get from their experiences. With this knowledge, the speakers make the message they deliver when they direct others' future actions. Deh reveals speakers' expectations that others will take an action based on the speakers' requests. While children still produce indirect arguments or even, they do not make any arguments, in some cases, adults directly provide arguments to support the claims of adults' deontic rights. Adults tend to talk about hypothetical events in the future in defending their ideas. It never happens in the case of children. The speakers of deh position themselves as the ones with higher epistemic and deontic rights. When the speakers manage future actions and the others do not agree with them, they do not insist that the recipients do what they ask. They realize that the recipients also have the right to decide. Ignoring others’ rights will harm their social relationships.
