Austronesian Lights the Way: The Origins of the Words for ‘Sun’ and Other Celestial Voca bulary in Old Ryukyuan

This paper examines the evidence for historical contacts between Ryukyuans and Austronesians and uses this as a starting point to explore the borrowing of celestial vocabulary from Austronesian languages into Proto or Old Ryukyuan. The previous hypotheses for the etymology of Proto-Ryukyuan *tenda ‘sun’ are discussed in detail, and this is followed by discussions on Old Ryukyuan words meaning ‘sun’, ‘sun, light’, ‘heaven’ and ‘moon’. In all of these cases it is argued the most plausible source languages are Austronesian, based on strong phonetic and semantic correspondences, geographic proximity to the Ryukyus or the Old Ryukyuan trade route, shared celestial worship, as well as the lack of cognates in Japanese.
