morphology and syntax, and since then she has published a number of papers on Karitana syntax (2003, 2008, 2012, 2013, 2014). Subsequently, a number of studies on the language has continued to be published, covering a wide array of topics. Ana Müller, for example has published papers on Karitiana semantics (2006, 2009, 2010, 2012). Ivan Rocha da Silva has produced a variety of works on Karitiana syntax (Rocha 2014), including two extensive descriptions on syntactical topics (2011, 2016). Ethnographically, Felipe Ferreira Vander Velden has documented a number of social aspects of the Karitiana people, specifically researching about the relations between indigenous peoples and animals. He has published a book about domestic animals among the Kartitiana (2012). Phonology Vowels Karitiana vowels can be distinguished by the features [high], [back], and [round], and can be short, long, oral or nasal. Consonants Karitiana also presents [͡tʃ] and [ʔ], but according to Luciana Storto (1999), the occurrence of the glottal stop is predictable, and [͡tʃ] is extremely rare, though it occurs in Karitiana's personal pronouns. The nasals are prestopped if they are preceded by an oral vowel, and poststopped if they are followed by one. The velar nasal is denasalized to before oral vowels in unstressed syllables, poststopped to before oral vowels in stressed syllables, and prestopped after oral vowels. are nasalized when surrounded by nasal vowels. Morphology In his PhD thesis, Caleb Everett (2006) listed six word classes for Karitiana. In general, Karitiana follows the general trend in Tupi languages of presenting little dependent-marking or nominal morphology, though it has a robust system of agglutinative verbal affixes. Valence-related verbal prefixes occur closer to the verb root than other prefixes, and according to Everett, the most crucial valency distinction in Karitiana is the distinction between semantically monovalent and polyvalent verbs as this plays an important role in verbal inflections and clausal constructions, such as the formation of imperative, interrogative and negative clauses, as well as in the establishment of grammatical relations. Karitiana presents a binary future/non-future tense suffix system and a number of aspect suffixes. It also presents desiderative inflection, an optional evidentiality suffix, a verb-focus system among other constructions. Karitiana presents a nominalizer suffix that is attached to verbs in order to derive nouns. In general, nouns serving as core arguments for a verb are left unmarked for case, but non-core arguments can receive allative and oblique case markers. Pronouns Only epicene pronouns
