What is Austronesian Language Family

First of all, this chapter surveys sociolinguistic features with a special emphasis on Japanese on Nauru Island. Second, it considers factors affecting the stability of the Nauruan language and Pidgin English. The cline theory helps to explain the degree of language decline. Both geographical and socio-political factors may account for them. In particular, the living environment is the most influential factor in a decline. This chapter concludes that the cline showing language decline is a valid argument. In Nauru, the Nauruan language on the island is one of the most stable languages today. Pidgin English is positioned in the middle of a continuum. Due to the linguistic dissimilarities between the indigenous language and Pidgin English, both languages can be maintained. The hierarchy of languages in Nauru today should be sustained in order to ensure the maintenance of the indigenous language and Pidgin English.
