Kanamarí language
Kanamarí, or Katukina-Kanamari, is a Katukinan language spoken by about 650 individuals in Amazonas, Brazil. It is considered endangered. The two principal varieties, Kanamari (Canamarí) and Katukina (Catuquina), are mutually intelligible, and have both been confused with neighboring languages with the same or similar names. Synonyms and dialect names include "Tshom-djapa, Tsohon-djapa, Wiri-dyapá, Pidá-dyapá, Kutiá-dyapá (Kadiu-diapa, Cutiadapa), Tucun-diapa, Bendiapa, Parawa." Etymology. The term "Katukina" is derived from the Proto-Purus term *ka-tukanɨ, meaning ‘speaker of an indigenous language’. As a result, it is used to refer to a few  different unrelated languages belonging to separate language families, including Panoan and Arawakan: Phonology. Consonants.

Grammar. The syntax of Kanamarí is characterized by ergative–absolutive alignment. The absolutive argument (i.e. the subject of intransitive verbs and the object of transitive verbs) is unmarked for  case, and usually appears following the verb phrase. If the absolutive argument is a pronoun it is represented by its free from. The ergative argument (i.e. the agent of transitive verbs) is marked for genitive case. If the agent is a pronoun, it is represented by a genitive prefix (as in "no-ti paiko" 'you killed grandfather' above). If the agent is a full noun, it is linked to the verb with the case marker "na", which phonologically attaches to the verb:
