Swahili is the official language of Tanzania. However, being a multilingual nation, English is widely spoken in this east African country. Other languages spoken in the country are the native languages of the various ethnic groups of the Bantu and Nilotic origin. Most of Tanzania’s population is confident in their mother tongue while the general populace has substantial knowledge of English. During the country’s British colonial era, English was commonly used in Tanzania.  English together with the Swahili language has been used as a medium of instruction in schools since Independence. As Tanzania has developed into one of the world’s most visited destinations, local people have been taking special language courses including English and other foreign languages to earn their livelihoods by guiding the tourists to the mountains, beaches and the national parks.
