Klata (also known as Clata, Giangan, Bagobo, Jangan) is an Austronesian language of the southern Philippines. It is spoken on the eastern slopes of Mount Apo in Davao del Sur Province, as well as in Davao City (Ethnologue) in an area stretching from Catalunan to Calinan.

The nearby Tagabawa language is also known as Bagobo, and is not to be confused with Giangan.


Klata is usually classified as one of the South Mindanao languages. Zorc (2019) proposes that it is not included among the South Mindanao languages, but only more distantly related to them within a wider subgroup of the Philippine languages which he calls "Southern Philippine".[2]


Traditional Klata (Giangan) population centers included the following barangays (see also Districts of Davao City).[3][better source needed][4][better source needed]

It is also spoken in Biao Joaquin, Calinan District[5] and in various parts of Baguio District.[6]

The Lipadas River separated the traditional Tagabawa and Clata territories, while the Talomo River (Ikawayanlinan) was the boundary separating the Tagabawas, Clatas, and Obos. The Davao River separated the traditional Bagobo and Clata territories.[3]


Klata has a five-vowel system consisting of the vowels /a, ɛ, ɔ, i, u/. It also has consonantal geminates. Consonantal phonemes are /p, b, t, d, k, g, ʔ, m, n, ŋ, s, h, l, j, w/.[7]
