The floor of a building, cave, tomb.
The floor of a traditional house, baluy, consists of floor planks about 5 cm. thick and from about 20 - 30 cm. wide. Planks run parallel with the house front and are divided into two sections by a center floor beam, gawa''an, with about ten planks to a side. The outside ends of the planks rest in grooves in the outside floor beams, mundīlig, and the other ends in grooves in the center floor beam so that the floor is level with the beams. The floors of other dwellings vary, depending on permanence of the structure. A hut, ābung, may have a flagstone, da'da'; cane, bilāu; wooden or an earthen floor; a pile hut, inappal, has either a wooden or cane floor; temporary shelters, such as a daytime shelter at the homesite, abadyaw, or daytime shelter away from the homesite, allung, usually have earthen floors, while a nighttime shelter away from the homesite, bāwi, or an evacuation shelter, bakwit, might have either an earthen or cane floor. A tomb, lūbu', has an earthen floor.
