names for the Davao River, a major waterway emptying into Davao Gulf near the city. The Obos, who inhabit the hinterlands of the region, called the river Davah (with a gentle vowel ending, although later pronunciation is with a hard v or b); the Klata (or Giangan/Diangan) called it Dawaw, and the Tagabawas called it Dabo. To the Obos, davah also means "a place beyond the high grounds" (alluding to settlements at the mouth of the river surrounded by high, rolling hills).
