This dissertation constitutes the first attempt at describing the grammar of Wampis (Spanish: Huambisa), a language spoken in the Peruvian Amazon. Wampis belongs to the so-called Jivaroan family of languages and is closely related to sister languages Awajun, Shuar, Shiwiar and Achuar. The grammar introduces the Wampis people and some aspects of their culture and history before analyzing the major aspects of the language from a grammatical perspective. Wampis possesses a complex prosodic system that mixes features of tone and stress. Vowel elision processes pervade most morphophonological processes. Nasalization is also present and spreads rightward and leftward through continuants and vowels. Every word in Wampis needs at least one high tone, but more can occur in a word. Morphologically, Wampis is a very rich language. Nouns and especially verbs have very robust morphology. Affixes and enclitics contribute different meanings to words. Some morphemes codify semantic categories that are not grammatically codified in many other languages, such as sudden realization, apprehensive and mirative modalities. An outstanding feature of Wampis is the pattern of argument indexation on the verb, which follows an uncommon pattern in which the verb agrees with the object (and not with the subject) if the object is a Plural Speech Act participant. Parallel to this pattern of argument indexation is the typologically uncommon pattern of object marking in Wampis, whereby a third person object noun phrase is not marked as an object if the subject is a first plural, second singular or second plural person. Wampis exhibits a nominative-accusative alignment. All notional objects (direct, indirect, object of applicative) are treated identically in the syntax. The preferred order is A P V. Wampis also possesses a sophisticated system of participant tracking, which is instantiated in the grammar via switch-reference markers. Another typologically uncommon feature of Wampis is the presence of a sub-system of switch-reference markers that track a participant that is not a subject. Throughout the twenty-one chapters of this grammar, other issues of Wampis related to different areas of phonology, morphology and syntax are also addressed and described from a functional and a typological perspective.

El cashibo-cacataibo es una lengua Pano hablada en la Amazonía peruana. Esta lengua presenta, pese a su número relativamente reducido de hablantes, una rica diversidad dialectal. Aunque la dialectología de este idioma ya ha sido documentada previamente por G. Tessmann y L. WistrandRobinson, entre otros, en el presente artículo, nos proponemos ofrecer una aproximación a la diversidad dialectal del cashibo-cacataibo a partir de datos obtenidos de primera mano y poniendo especial énfasis en la documentación de los aspectos fonológicos que determinan las isoglosas que separan los dialectos cashibo-cacataibo, ello sin dejar de lado aspectos relevantes en los planos léxico y morfosintáctico. Nuestras conclusiones, derivadas de los datos que hemos recogido, convergen con los resultados planteados previamente: el cashibo-cacataibo constaría de cuatro dialectos (más uno probablemente extinto) con diversos grados de similitud entre los mismos. / Cashibo-Cacataibo is a Panoan language spoken in the Peruvian Amazon. Despite its relatively small number of speakers this language features a rich dialectal diversity. Although this dialectal situation has previously been documented by G. Tessmann and L. Wistrand, among others, in this article we aim to offer an approach to the dialectology of this language from firsthand data and with an emphasis on the documentation of the phonological aspects that determine the isoglosses separating the Cashibo-Cacataibo dialects. The paper also include references to lexical and morphosyntactic aspects. The conclusions from the data we have collected converge with the results obtained by other scholars: the Cashibo-Cacataibo language consists of four extant dialects (plus an extinct one) with varying degrees of similarity between them.
