Local Native Americans, the Kumeyaay, called this location mat kulaaxuuy (mat kəlaːxuːj), land of holes (mat = ). The topographic feature that gave rise to the name "holes" is uncertain; it probably refers to sea-level caves located on the north-facing bluffs, which are visible from La Jolla Shores. It is suggested that the Kumeyaay name for the area was transcribed by the Spanish settlers as La Jolla. Another suggestion for the origin of the name is that it is an alternative spelling of the Spanish phrase la joya, which means . Despite being disputed by scholars, this derivation of the name has been widely cited in popular culture. This supposed origin gave rise to the nickname "The Jewel". The name may also come from the Spanish La Hoya, meaning a geographic hollow. Different spelling conventions over the years would permit this to be written as La Jolla.
