Nevada is a state located in the western region of the United States. The capital is Carson City and the largest city is Las Vegas. The state's nickname is Silver State, due to the large number of silver deposits that were discovered and mined there. "Sagebrush State" and "Battle Born State" are its alternative nicknames. In 1864, Nevada became the 36th state to enter the union, and the phrase "Battle Born" on the state flag reflects the state's entry on the Union side during the American Civil War. Its first nonnative settlement was called Mormon Station.

Nevada is the seventh-largest state in area, and geographically covers the Mojave Desert in the south to the Great Basin in the north. It is the most arid state in the Union. Approximately 86% of the state's land is owned by the U.S federal government under various jurisdictions both civilian and military. As of 2008, there were about 2.6 million residents, with over 85% of the population residing in the metropolitan areas of Las Vegas and Reno. The state is well known for its easy marriage and divorce proceedings, entertainment, legalized gambling and, in eight out of its 16 counties, legalized active brothels.

The name "Nevada" comes from the Spanish Nevada [ne??aða], meaning "snowfall",[6] after the Sierra Nevada ("snow-covered mountains") mountain range.

The second syllable of "Nevada" is correctly pronounced with the /æ/ vowel of "bad". Many people from outside the Western United States pronounce the name /n??v??d?/, with the /??/ vowel of "father"; this is closer to the Spanish pronunciation of 'a', but is considered incorrect by locals. Notably, George W. Bush made this faux pas during his campaign for the 2004 US Presidential Election. Vindication later came when President Bush campaigned at the Reno-Sparks Convention Center on June 18, 2004. The president opened his talk by proclaiming that "It's great to be here in /n???væd?/," emphasizing the correct 'a' – the crowd roared its approval when he light-heartedly noted "You didn't think I'd get it right, did ya?". President Bush subsequently carried the state in the election.

Nevada is made up of mostly desert and semiarid climate regions, daytime summer temperatures sometimes may rise as high as 125 °F (52 °C) and nighttime winter temperatures may reach as low as ?50 °F (?45.6 °C). The winter season in the southern part of the state, however, tends to be of short duration and mild. Most parts of Nevada receive scarce precipitation during the year. Most rain falls on the lee side (east and northeast slopes) of the Sierra Nevada Range. The average annual rainfall per year is about 7 inches (18 cm); the wettest parts get around 40 inches (102 cm).
