The word "orangutan" appears, in its older form "urangutan", in a variety of premodern sources in the Old Javanese language. The earliest of these is the Kakawin Ramayana, a ninth-century or early tenth-century Javanese adaption of the Sanskrit Ramayana. In these Old Javanese sources, the word "urangutan" refers only to apes and not to forest-dwelling human beings. The word was not originally Javanese, but was borrowed from an early Malayic language at least a thousand years ago. Hence the ultimate origin of the term "orangutan" as denoting the "Pongo" ape was most likely Old Malay.
