Lahad Datu
The Ida'an language has been described as having three dialects: Ida'an "proper" (spoken in Sagama and several villages west of Lahad Datu), Begak (spoken in Ulu Tungku and several villages east of Lahad Datu), and Subpan (spoken in the districts of Kinabatangan and Sandakan). These dialects correspond to three ethnic groups who originally formed a single group.
