history: · branch of knowledge dealing with past events · aggregate of past events
köken: From พงศ์ (pong, “family; genealogy”) + อวตาร (à-wá-dtaan, “avatar: divine descent to the earth”); ultimately from वंश (vaṃśa, “family; dynasty; genealogy”) + अवतार (avatāra, “avatar”); literally "avatar of (royal) family", based on the old belief that royals were gods incarnate. Cognate with Khmer ពង្សាវតារ (pɔɔngsaawtaa).
