Wao Terero, the Waorani (Huaorani) language, earlier also known as Sabela and Awishiri3 (also Wao, Huao, Auishiri, Aushiri, Ssabela; pejorative: "Auka", "Auca"3), is a language isolate spoken by the Waorani people, an Indigenous people living in the Amazon rainforest between the Napo and Curaray Rivers in Ecuador. It is considered Vulnerable by the UNESCO Atlas of the World's Languages in Danger.4 A small number of speakers among uncontacted groups may live in Peru.

Classification

Wao Terero is not known to be related to any other language.3 However, it forms part of Terrence Kaufman's (2007) Yaguan branch of his Záparo-Yaguan proposal.5 Marcelo Jolkesky (2016) also identifies a number of lexical similarities with Yaruro.6

Status

Multiilingalism is more common among the younger generations; monolinguals in Wao Terero tend to be elderly, and the number of Spanish monolinguals is increasing, as is bilingualism in Spanish, Shuar, and Lowland Kichwa.3 Wao Terero is considered endangered due to growing bilingualism in Kichwa and Spanish and diminishing Wao Terero usage among youth.17

Geographical distribution

Wao Terero is primarily spoken in the Waorani Ethnic Reserve, which is the largest indigenous reserve in Ecuador. Other areas where it is spoken include Pastaza and Napo provinces (including the towns of Puyo and Coca), Yasuní National Park, and the Taromenani Tagaeri Intangible Zone.3: 1191 

Dialects

The Taromenani ‘people living at the end of the path’ are viewed as "culturally and linguistically “similar but different” from the Waorani". Speakers of the language distinguish variation across communitnes, such as variation in the realization of nasal spreading.3: 1193 

Phonology

Phonotactics

The syllable structure of Wao Terero is (C)V, with frequent vowel sequences.3

Consonants

The alveolar tap [ɾ] is an allophone of /d/, though written separately, and the palatal stop [ɟ] is an allophone of /j/. Nasal consonants are considered "semi-phonemic", as nasalization is, in some instances, clearly allophonic due to progressive, or rightward, nasalization.3

Nasal (m ) (n) (ɲ ⟨ñ⟩) (ŋ ⟨ng⟩)
Approximant w ɟ~j ⟨y⟩

Vowels

Wao Terero distinguishes oral and nasal vowels, which are sometimes written using a diaeresis. Phonetic vowel length occurs, and appears contrastive, but is analyzed as sequences of two of the same vowel, sometimes thought to be due to consonant elision between vowels. Creaky-voiced or laryngeal vowels also occur at word and phrase boundaries, but their phonemic status is uncertain.3

Suprasegmentals

Stress in Wao Terero is predictable, as in CVV syllables (where C is a wildcard symbol for any consonant and V is a wildcard for any vowel), stress falls on the final syllable, but in CV syllables, it falls on the penultimate syllable.3

Morphology

Pronouns

Wao Terero distinguishes inclusive pronouns and singular, dual, and plural number.
