dinheiro. Nadëb and Nïkâk, on the other hand, have polysyllabic roots. Nïkâk allows a single prefix per word, whereas Nadëb, which lies outside the Vaupés language area, is heavily prefixing and polysynthetic: Up to nine prefixes per word (which is highly unusual for the Amazon), with incorporation of nouns, prepositions, and adverbs. Genetic relations Rivet (from 1920), Kaufman (1994) and Pozzobon (1997) include Puinave within the family. However, many of the claimed cognate sets are spurious. Henley, Mattéi-Müller and Reid (1996) present evidence that the Hodï language (also known as Yuwana) is related. Puinavean forms part of a hypothetical Macro-Puinavean family along with the Arutani–Sape families and the Máku language. Macro-Puinavean is included in Joseph Greenberg's larger Macro-Tucanoan stock, but this is universally rejected. Another spurious larger grouping is Morris Swadesh's Macro-Makú. Vocabulary Loukotka (1968) lists the following basic vocabulary items for the Macú languages.
