Bahamians are people originating or having roots from The Commonwealth of The Bahamas. One can also become a Bahamian by acquiring citizenship. The Bahamas is an island country within the Lucayan Archipelago of the West Indies in the North Atlantic. The name Bahamas is derived from the Lucayan name Bahama ('large upper middle island'), used by the indigenous Taíno people for the island of Grand Bahama. Tourist guides often state that the name comes from the Spanish baja mar ('shallow sea'). Wolfgang Ahrens of York University argues that this is a folk etymology. Alternatively, it may originate from Guanahani, a local name of unclear meaning.
