The origins of ancient Sardinian, also known as Paleo-Sardinian, are currently unknown. Research has attempted to discover obscure, indigenous, pre-Romance roots. The root "s(a)rd", indicating many place names as well as the island's people, is reportedly either associated with or originating from the Sherden, one of the Sea Peoples. Other sources trace instead the root "s(a)rd" from , a legendary woman from the Anatolian Kingdom of Lydia, or from the Libyan mythological figure of the Sardus Pater "Babai" ("Sardinian Father" or "Father of the Sardinians").
