Nevada [SEP] Etymology and pronunciation
The name "Nevada" comes from the Spanish "nevada" , meaning "snow-covered". Nevadans pronounce the second syllable with the "a" as in "trap" () while some people from outside of the state can pronounce it with the "a" as in "palm" (). Although the latter pronunciation is closer to the Spanish pronunciation, it is not the pronunciation used by Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternate (quasi-Spanish) pronunciation of Nevada, though the bill was not supported by most legislators and never received a vote. The Nevadan pronunciation is the one used by the state legislature. At one time, the state's official tourism organization, TravelNevada, stylized the name of the state as "Nevăda", with a breve over the "a" indicating the locally preferred pronunciation, which was also available as a license plate design until 2007.
