Evidence and Models of Linguistic Relations: Subgroups, Linkages, Lexical Innovations, and Borneo

Abstract

Abstract: Several recent studies place the languages of Borneo into one of two large groups, the Greater North Borneo subgroup and the Barito–Basap linkage. These same studies place both Greater North Borneo and Barito–Basap with the Western Indonesian subgroup, a large subgroup which is claimed to be a primary branch of Malayo-Polynesian. This paper demonstrates that the exclusively lexical evidence used to justify such subgroups is invalid as subgrouping evidence. Instead, it is shown that the languages of Borneo developed a small number of Bornean-only lexical items through contact, borrowing, and early innovations within the first Proto-Malayo-Polynesian-speaking settlers of the island. To support these claims, a detailed description of both the methods of lexical innovation evaluation as well as the types of linguistic relations that such lexical innovations support is undertaken in this paper. A new standard for the use of lexical evidence in subgrouping arguments is established, with wide-ranging implications for not only the classification of Bornean languages but of western Malayo-Polynesian languages in general.
