Charol. See how shiny it is?
One branch of the Taitano clan is called Charot.
Charol is a Spanish word with several meanings. It can be either lacquer/varnish, patent leather or, in some Spanish-speaking countries, a tray. The root meaning is something that is permanently shiny or varnished. In that sense, a patent leather shoe is a zapato de charol in Spanish.
Family lore says that an ancestor of this branch of Taitanos was given a gift of shoes, zapatos de charol. Chamorros could not pronounce final L, so it became charot.
