A place name is tautological if two differently sounding parts of it are synonymous.
Tautological place names are systematically generated in languages such as English and Russian, where the type of the feature is systematically added to a name regardless of whether it contains it already.
For example, in Russian, the format "Ozero X-ozero" (i.e. "Lake X-lake") is used.
Examples include the Outerbridge Crossing named after Eugenius Harvey Outerbridge, the Hall Building of Concordia University named after Henry Foss Hall, and Alice Keck Park Memorial Gardens in Santa Barbara named after Alice Keck Park.
Asterisks (*) indicate examples that are also commonly referred to without the inclusion of one of the tautological elements.
