Approximately 10 % of Tanzanians speak Swahili as a first language , and up to 90 % speak it as a second language . Most Tanzanians thus speak both Swahili and a local language ; many educated Tanzanians are trilingual ; also speaking English . The widespread use and promotion of Swahili is contributing to the decline of smaller languages in the country .
