Chamacoco is classified as a Zamucoan language, along with Ayoreo. Both languages are considered endangered.4 There is relatively little information about the Zamucoan family.
Chamacoco speakers live in the northeastern part of the Chaco Boreal at the origin of the Río Verde in Paraguay.5 Four dialects of Chamacoco have been identified: Héiwo, in the Fuerte Olimpo area; Ebidóso and Hório, spoken in the Bahía Negra region; and Tomaráho, in the Alto Paraná Atlantic forests.6
The speakers of Hório and Ebidóso were estimated to be 800 in 1970. Fewer than 200 people spoke Tomaráho then. Back in 1930, over 2000 people were estimated to speak Chamacoco.7
Verb inflection is based on personal prefixes and the language is tenseless.8 For example, chɨpɨrme teu dosh means "the kingfisher eats fish", while chɨpɨra teu wichɨ dosht means "the kingfisher will eat fish." Nouns can be divided into possessable and non-possessable. Possessable nouns are characterized by a prefixation whereby the noun agrees with the possessor or genitival modifier.9 There is no difference between nouns and adjectives in suffixation.10 The syntax is characterized by the presence of para-hypotactical structures.11 The comparison of inflectional morphology has shown remarkable similarities with Ayoreo and Ancient Zamuco.12
An Ɨshɨr (Chamacoco) Living Dictionary is currently[as of?] under construction,13 spearheaded by Living Tongues Institute for Endangered Languages. This project is being curated in close collaboration with Ɨshɨr language activists such as Andres Ozuna Ortiz.
All vowels except for /ɑ, ə/ have nasalized forms.15
