Classic analyses of propositional attitude reports (building on Hintikka
1969) assume that attitude verbs compose with a clausal argument that
denotes a proposition. I use original fieldwork data to demonstrate that
Amahuaca (Panoan; Peru) attitude reports involve high adjunct
switch-reference clauses rather than clausal complements to an attitude
verb. This structure raises issues for the traditionally assumed
compositional semantics of attitude reports. I argue that the approaches of
Kratzer (2006) and Moulton (2015), which do not assume that attitude verbs
compose directly with propositional internal arguments, can be extended to
account for the Amahuaca data. Amahuaca therefore provides novel empirical
support for this approach to the semantics of attitude reports.
