Arkansas ( ; ) is a state located in the southern region of the United States. Arkansas shares a border with six states, with its eastern border largely defined by the Mississippi River. Its diverse geography ranges from the mountainous regions of the Ozarks and the Ouachita Mountains, which make up the U.S. Interior Highlands, to the eastern lowlands along the Mississippi River. The capital and most populous city is Little Rock, located in the central portion of the state.

Name

The name Arkansas derives from the same root as the name for the State of Kansas. The Kansas tribe of American Indians are closely associated with the Sioux tribes. The word is a French pronunciation of a Quapaw (a related "Kaw" tribe) word meaning "land of downriver people" or "people of the south wind". The pronunciation of Arkansas was made official by an act of the state legislature in 1881 after a dispute between the two U.S. Senators from Arkansas. One wanted to pronounce the name and the other wanted .The name Arkansas has been pronounced and spelled in a variety of fashions. The region was organized as the Territory of Arkansaw on July 4, 1819, but the territory was admitted to the Union as the State of Arkansas on June 15, 1836. The name was historically , and several other variants. In 1881, the Arkansas General Assembly passed the following concurrent resolution (Arkansas Statutes, Title 1, Chapter 4, Section 105):

Whereas, confusion of practice has arisen in the pronunciation of the name of our state and it is deemed important that the true pronunciation should be determined for use in oral official proceedings.

And, whereas, the matter has been thoroughly investigated by the State Historical Society and the Eclectic Society of Little Rock, which have agreed upon the correct pronunciation as derived from history, and the early usage of the American immigrants.

Be it therefore resolved by both houses of the General Assembly, that the only true pronunciation of the name of the state, in the opinion of this body, is that received by the French from the native Indians and committed to writing in the French word representing the sound. It should be pronounced in three (3) syllables, with the final "s" silent, the "a" in each syllable with the Italian sound, and the accent on the first and last syllables. The pronunciation with the accent on the second syllable with the sound of "a" in "man" and the sounding of the terminal "s" is an innovation to be discouraged.

Geography

The Mississippi River forms most of Arkansas's eastern border, except in Clay and Greene counties where the St. Francis River forms the western boundary of the Missouri Bootheel, and in dozens of places where the current channel of the Mississippi has meandered from where it had last been legally specified. Arkansas shares its southern border with Louisiana, its northern border with Missouri, its eastern border with Tennessee and Mississippi, and its western border with Texas and Oklahoma.
