Austronesian is the largest well-established family in the world in terms of the number of languages, while also covering a huge area of the globe. It includes some very large as well as many very small languages, and many are poorly documented. Despite the internal diversity, a substantial amount of phonological, lexical, and morphosyntactic reconstruction has been achieved, and we have a much more solid idea about subgrouping than we do for many more diffuse language families. The linguistic and archeological evidence points to a Proto-Austronesian origin about 5000 years ago in the area of Taiwan.
