rengga

Could you clarify what you mean by "rengga"? The term can refer to different things in different contexts (for example a linguistic or cultural sense in Indonesian languages, a geographic place name, or a personal name). To write a precise, neutral wiki-style article, please specify which sense you want me to cover. If you’d like, I can provide a general neutral stub that surveys possible senses without committing to a specific interpretation, then expand once you indicate the focus.
