practice of abusing and murdering disobedient wives is detailed. Language There are five main languages spoken on Tanna: the southern language of Kwamera and the South-Western language adjacent to the slopes of Tokosmera, of which there are many dialects spoken by very small groupings, constitute two of the languages. The remaining majority of Tanna islanders speak four dialects, being North Tanna in the northwest, Lénakel in the west-central area near Lénakel, and the middle bush dialect in the central plateau of the island, which is very close to Lenakel Whitesands in the northeast near Whitesands. These are generally grouped into the Tanna languages family, which is a subgroup of the South Vanuatu languages, an Austronesian language branch. According to Ethnologue, each is spoken by a few thousand, and Lénakel, with about 16,000 speakers, is one of the languages of Vanuatu with the most speakers. Many people on Tanna also speak Bislama, which is one of Vanuatu's three official languages (together with English and French). Economy The island is one of the most fertile in Vanuatu and produces kava, coffee, coconut, copra, and other fruits and vegetables. Recently, tourism has become more important, as tourists are attracted to the volcano and traditional culture. To help preserve the integrity of culture as a tourism asset, only local people are permitted to act as guides. There are various types of accommodation on the island. Cultural references Five men from Tanna's Prince Philip Movement cargo cult, which considers Prince Philip, Duke of Edinburgh a god, were brought to the United Kingdom as part of the Channel 4 reality show Meet the Natives in 2007. Part of their itinerary included an off-screen meeting with the prince. In An Idiot Abroad, Series 2, Episode 1, Karl Pilkington visited Tanna and discussed the Prince Philip Movement and met those who visited Windsor Castle. In 2009 the Travel Channel aired Meet the Natives: USA, which brought five men from another group from Tanna to the United States. Their tribe reveres Tom Navy, an American World War II sailor who generations ago had taught the inhabitants to live in peace. The Tanna ambassadors were taken across, visiting five states, and eventually meeting former United States Secretary of State Colin Powell and verifying with him that the spirit of peace taught by Tom Navy lives on in then US President, Barack Obama.
