The Oceanic languages, a subgroup within the Austronesian language family, comprise at least 450 languages in the geographical area encompassing Melanesia, Micronesia and Polynesia. The articles in this book deal with morphosyntactic properties related to sentence types and nominal expressions in under-explored and endangered Oceanic languages. These properties may vary within the family, they give rise to new empirical generalizations, and they illustrate properties that are relevant for theoretical developments in modern linguistic theory.
