Oklahoma
Oklahoma is a state in the South Central region of the United States, bordered by the state of Texas on the south and west, Kansas on the north, Missouri on the northeast, Arkansas on the east, New Mexico on the west, and Colorado on the northwest
It is the 20th-most extensive and the 28th-most populous of the 50 United States. The state's name is derived from the Choctaw words okla and humma, meaning 'red people'. It is also known informally by its nickname, 'The Sooner State', in reference to the non-Native settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of Congress that opened the door to homestead settlement.
