The rapid spread of Indonesian as the national language of Indonesia has diminished the significance of local languages. On the island of Sumba, this shift has displaced a once vibrant tradition of ritual poetic speech, but has also given rise to new and hybrid forms of poetic expression. This book analyzes language change in relation to political marginality, revealing that political coercion or cognitive process of "style reduction" may offer a partial explanation, but equally important is the role of linguistic ideologies.
