The etymology of the name "Badjao" is uncertain. Some believe it comes from the Malay "bajau" or "bajo" meaning "sea nomad" or "sea gypsy". In Malaysia and Singapore they are called "Orang Laut", which means "Sea People". The Sama call themselves "Sama", which means "those who travel the seas".
The Sama originated in the southern Philippines and have lived throughout the Sulu Archipelago for the past 1000 years. They lived mostly in the waters of Tawi-Tawi, Sulu, Basilan and Zamboanga. It is believed that they moved on from there after the arrival of the Spanish and are currently distributed in the coastal areas of Sabah and Sarawak in Malaysia, the Riau Archipelago and Kalimantan in Indonesia and some parts of Brunei.
The Sama are Austronesian people, and their language, Sama, belongs to the Sama–Bajau languages of the Malayo-Polynesian branch of the Austronesian language family. This language is the primary language of the Sama people, but their spoken language is influenced by the languages of the surrounding region.
