From the introduction: "The purpose of this study is to present some of the major morphosyntactic characteristics of eight Arawakan languages spoken in Brazil. [...] The five areas of morphosyntax which are treated in tern in the following sections are: word order, case marking, verb morphology, coordination, and subordination. As will be seen in section 3, much of the morphosyntactic complexity of these languages is found in the verb, and certain phenomena that in other languages would be dealt with in other parts of the syntax are treated in that section, including: valence-changing devices such as causatives, passives and reflexives; negation; and gender agreement; for each of these, the discussion is extended to cover related aspects of the syntax, wherever the sources provide material for this."
