Daakaka [ⁿdaːkaka] (also known as Dakaka, South Ambrym and Baiap) is a native language of Ambrym, Vanuatu. It is spoken by about one thousand speakers in the south-western corner of the island.

Most children in the region still acquire Daakaka as a first language, but it is under threat by significant socio-economic changes and the dominant use of Vanuatu's official languages, Bislama, English and French, in education and in official contexts.

The system of consonantal phonemes is fairly typical for the region. Voiced stops are prenasalized. The difference between bilabial consonants with and without a labio-velar release is relevant only before front vowels.

There are seven phonemically distinct vowel qualities, with one long and one short vowel phoneme for each variety, plus a marginally phonemic ə [ə]. The distinction between mid and open-mid vowels is only phonemic after alveolar consonants, as in tee [tɛː] "axe" vs. téé [teː] "see".

The four major word classes are nouns, verbs, adjectives and adverbs. Only nouns can stand in argument position, only verbs and some adjectives can be used as predicates without the copula i, only adjectives can be used as attributes to nouns without further modification. The two biggest word classes by far are nouns and verbs.

There are three subclasses of nouns. The biggest subclass consists of 'general nouns' such as em "house" or myaop "volcano"; in contrast to the other two classes, these nouns do not need to specify a possessor, they cannot be inflected and they cannot be directly followed by another noun phrase. 'Inflected nouns' always indicate their possessor by a person-number ending:

kus-uk
