This book investigates the historical development and classification of the Oceanic languages, a vast subgroup of the Austronesian language family spoken across the Pacific Ocean. Malcolm Ross, a distinguished linguist with extensive experience in Austronesian languages, presents a comprehensive analysis based on comparative reconstruction and lexicostatistical data. The work aims to establish the internal relationships within the Oceanic subgroup and its position within the broader Austronesian family, detailing the evidence for proposed subgroupings and historical sound changes.

This book is recognized as a foundational text in the study of Oceanic linguistics, drawing on decades of research by leading scholars in the field. Its detailed comparative work and rigorous methodology have made it an indispensable resource for linguists specializing in Austronesian languages and the history of the Pacific. The work is noted for its thoroughness and its contribution to understanding the complex linguistic landscape of Oceania.
