Kenya (pron.: /ˈkɛnjə/ or /ˈkiːnjə/), officially the Republic of Kenya, is a country in East Africa that lies on the equator. With the Indian Ocean to its south-east, it is bordered by Tanzania to the south, Uganda to the west, South Sudan to the north-west, Ethiopia to the north and Somalia to the north-east. Kenya has a land area of 580,000 km2 and a population of a little over 43 million residents. The country is named after Mount Kenya, a significant landmark and second among Africa's highest mountain peaks. Its capital and largest city is Nairobi. Modern day Mt. Kenya was originally referred to as "Mt. Kirinyaga" by the indigenous people. "Kirinyaga or Kerenyaga, meaning 'mountain of whiteness' because of its snow capped peak"; The name was subsequently changed to Mt.Kenya due to the inability of the British to pronounce "Kirinyaga" correctly.
