Most locals will be happy to teach you a few Norwegian words and phrases over a few beers at one of the many pubs and bars. Use them with care down below the Arctic Circle, as the local lingo is peppered with colourful profanities.
The University (http://www.uit.no) offers several Master programs in English, including the Peace Studies, Visual Anthropology, the International course of linguistics, Indigenous studies etc. Check if your university has some kind of co-operation with or recognition of the University of Tromsø.
Norwegian classes are hard to come by. Immigrants receive basic education at Voksenopplæringen i Tromsø kommune. The University organizes classes for its international staff. Foreigners who just want a quick introduction, have few or no options. Neither is there anything on offer for short term visitors who would like to learn Sami.
