Kawi (from Sanskrit: kavi, "poet") is a literary and prose language on the islands of Java, Bali, and Lombok, based on Old Javanese, a language with a sizable vocabulary of Sanskrit loanwords. Kawi is the ancestor language of modern Javanese. The name "kawi" is derived from the root ku, which in Sanskrit means “poet”, and, in derived forms, a “wise, educated man”. The syllabic meter of Kawi poetry is sekar kawi, which means “flowers of the language”, sekar itself deriving from the Sanskrit "sekhara" (“garland”). All Javanese languages are hierarchical and stratified, with strict social conventions for appropriate language subsets to be used for one's superiors or social and cultural functions. Kawi is commonly considered the pinnacle language.
