Brunei

According to legend, the name "Brunei" is derived from the exclamation Baru nah! meaning "that's it!" or "there", shouted by Sultan Muhammad Shah (also known as Awang Alak Betatar), the first sultan of Brunei. He uttered the declaration upon arriving at the Brunei River. In the 14th century, it was renamed Barunai, possibly deriving its name from Sanskrit वरुण (váruṇa) possibly meaning "seafarers" or "to surround" (see Borneo) or referring to Varuna, a Hindu sky, rain, and ocean deity. The Nation of Brunei, Abode of Peace is a sovereign state located on the island of Borneo in Southeast Asia.
