"In summary, this grammar is an outstanding reference work, with an impressive breadth of coverage and depth of analysis. It gives the impression that every part of Hupgrammar, from phonology to morphosyntax and semantics, receives the comprehensive treatment it deserves, and it is thus a valuable source for typologists. But it is also highly recommended not only to readers interested in Amazonian languages and cultures, but to anyone who relies on, or simply enjoys, sophisticated linguistic descriptions."Frank Seifart in: Anthropoligical Linguistics 2/2009
