Baroque accretions and isolation

A case study of grammatical complexity in complex social situations in Solomon Islands

| Australian National University
This paper presents a case study comparing two Papuan languages of Island Melanesia, Lavukaleve and Touo, with their Oceanic neighbours, exploring differing outcomes of language contact in micro-contact situations. Social/geographic isolation has been thought to preserve or enable structural complexity, measured using a complexity index. It is shown that each of the Papuan members of the contact situations to be described is structurally more complex than its Oceanic neighbours, but of these, the structurally more complex language is the socially/geographically more isolated. Among these languages, while there is a relationship between isolation and complexity, there is a less strong relationship between being isolates and being complex. Thus, in this case at least, isolates are not necessarily more complex by virtue of being isolates.
Keywords: language isolates, Papuan languages, Oceanic languages, Solomon Islands, structural complexity
