Unhappy with the policy of using English as the medium of instruction in secondary schools in Tanzania which left his students bewildered, a Norwegian volunteer teacher in Ipinda, Tukuyu, south western region of Tanzania decided that his students would probably cope with the foreign language only after they were grounded first in the structure of their own languages - Nyakyusa and Swahili. As a trilingual dictionary was not available, he set out to compile one and this well producced dictionary is the product. Words, examples and usages are included.
