Kota Kinabalu is named after Mount Kinabalu, about 90 kilometres east-northeast of the city. The meaning and origin of the name "Kinabalu" is uncertain. One theory suggests it means "Chinese widow", where "Kina" meaning "Chinese" (person) in Kadazandusun language, and "balu" meaning "widow" in Malay language. This theory derives from a folk tale about a Chinese prince who came to the mountain in search of a giant pearl which was guarded by a dragon at the top of the mountain. While he was here, he married a local woman but later returned to China and left the woman heartbroken. Alternatively, it is also argued that "Kinabalu" or "Akinabalu" is the name of the dragon which guards the giant pearl itself. Another theory suggests that the term is derived from the name "Aki Nabalu" meaning the "revered place of the dead", in which, "Aki" means "ancestors" or "grandfather", and "Nabalu" being a name for the mountain in the Dusun language. Finally there is also a source claiming that the term originated from "Ki Nabalu", where "Ki" meaning "have" or "exist", and "Nabalu" meaning "spirit of the dead".
