The Western Malayo-Polynesian languages, also known as the Hesperonesian languages, are those Malayo-Polynesian languages which are not in the Central-Eastern branch. Since there are no features which define these languages positively as a group, many recent classifications have abandoned it. In Wouk et al. some of its languages have been split off in an "Outer" group as a primary branch of Malayo-Polynesian, and the rest retained in an "Inner" group within a Nuclear Malayo-Polynesian branch. These Inner and Outer groups may also be called the Borneo-Philippines languages and Sunda-Sulawesi languages, after their geographic spread.
