Kamayo (Kinamayo or alternatively spelled Camayo), also called Kadi, Kinadi, or Mandaya, is a minor Austronesian language of the central eastern coast of Mindanao in the Philippines.
Kamayo is a language widely used by the Mandayas in the Davao Oriental areas. It is closely related to Tandaganon and Surigaonon. Dialect variations are caused by mixed dialect communications such as the Cebuano language in barangays Mangagoy and Pob. Bislig. The towns of Barobo, Hinatuan, and Lingig has a distinct version spoken. A suffix is usually added to most adjectives in the superlative form; for example, the word gamay in Cebuano ('small') is gamayay while the word dako ('big') is spoken as dako-ay in Bislig.
Kamayo dialects can be classified as North Kamayo and South Kamayo.[2]
