Kwadi is an extinct "click language" once spoken in the southwest corner of Angola. It became extinct around 1960. There were only fifty Kwadi in the 1950s, of whom only 4–5 were competent speakers of the language. Three partial speakers were known in 1965, but in 1981 no speakers could be found. Salvage work was carried out in 2014 with two rememberers who had acquired the language from an old speaker while they were children.
Although Kwadi is poorly attested, there is enough data to show that it is a divergent member of the Khoe family, or perhaps cognate with the Khoe languages in a Khoe–Kwadi family. It preserved elements of proto-Khoe that were lost in the western Khoe languages under the influence of Kxʼa languages in Botswana, and other elements that were lost in the eastern Khoe languages.
Kwadi was alternatively known by varieties of the words Koroka (Ba-koroka, Curoca, Ma-koroko, Mu-coroca) and Cuanhoca.
Zorotua, or Vasorontu, was apparently a dialect.
Phonology
Vowels
Kwadi is tentatively reconstructed as having the seven oral vowels the three nasal vowels . Diphthongs seem to have been and . The status of /ao/ is not certain, and /oa/, /ua/ may have been allophones.
In disyllabic words, the second consonant is predominantly /m/, /n/, /l/, /d/, /b/, and it is possible those were the only consonants allowed within morphemes in native words, as would be typical for the area. 1st person plural may have distinguished clusivity. Object pronouns are suffixed with -le/-de, except for the first person dual object pronoun, which is just mu. Possessive pronouns are the same as the subject form, except for the first person singular possessive pronoun, which is tʃi. Third person pronouns are simply the demonstratives, which are formed with a demonstrative base ha- followed by a gender/number suffix.

The known possessive pronouns are tʃi 'my' and ha 'his'. From the Khoe languages, it's not expected that all pronouns had distinctive possessive forms.
Nouns
Kwadi nouns distinguished three genders (masculine, feminine, and common), as well as three numbers (singular, dual, and plural). Some nouns form their plural with suppletion. For example: tçe "woman" vs. tala kwaʼe "women". The attested paradigm of nominal suffixes for masculine and feminine nouns is given below.
