Missouri ( ) is a state in the Midwest region of the United States bordered by Iowa, Illinois, Kentucky, Tennessee, Arkansas, Oklahoma, Kansas and Nebraska. Missouri is the 18th most populous state. It comprises 114 counties and one independent city. Missouri's capital is Jefferson City. The four largest urban areas are, in descending order, St. Louis, Kansas City, Springfield, and Columbia. Missouri was originally acquired from France as part of the Louisiana Purchase and became defined as the Missouri Territory. Part of the Missouri Territory was admitted into the union as the 24th state in August 10, 1821.

Missouri mirrors the demographic, economic and political makeup of the nation with a mix of urban and rural culture. It has long been considered a political bellwether state. With the exception of the 1956 and 2008 presidential elections, Missouri's election results have accurately predicted the next President of the United States since United States presidential election, 1904. It has both Midwestern and Southern cultural influences, reflecting its history as a border state. It is also a transition between the eastern and western United States, as St. Louis is often called the "western-most eastern city" and Kansas City the "eastern-most western city." Missouri's geography is highly varied. The northern part of the state lies in dissected till plains while the southern part lies in the Ozark Mountains a (dissected plateau), with the Missouri River dividing the two. The confluence of the Mississippi and Missouri rivers is located near St. Louis.

Etymology and pronunciation

The state is named after the Missouri River which in turn is named after the Siouan Indian tribe whose Illinois name, ouemessourita (wimihsoorita), means "those who have dugout canoes". The etymology lies behind Bob Dyer's tribute song, "River of the Big Canoes".

The pronunciation of the final syllable of "Missouri" is a matter of some controversy, with some insisting on a relatively tense vowel (as in "meet"), while others prefer a lax vowel ("mitt" or "mutt"). The most thorough study of the question was done by dialectologist Donald Max Lance. From a linguistic point of view, there is no correct pronunciation, but rather, there are simply patterns of variation, diachronic as well as synchronic, according to such divisions as geography, age, education, and/or rural vs. urban location. In general, the schwa vowel correlates with proximity to Kansas City, with older speakers (born before 1945), with lower levels of formal education and rural location. Lance notes less controversial but also systematic variations in pronunciation: the second consonant is most often voiced ("misery") but unvoiced by some speakers ("missive"), and the medial vowel is variously raised and unrounded ("lurk") or rounded ("lure").
