Swedish is a pluricentric language in the sense that it has official status in more than one nation. Swedish is the main language of Sweden but spoken by a minority of 5.4% in Finland. Because of national differentiation, the varieties of Swedish differ from each other in certain respects. Variation in pronunciation, lexis and syntax are well documented. However, differences in pragmatic aspects of language use, such as expressions of politeness, intimacy and formality, have not been researched systematically to date. This paper has its background in a project which aims to fill this research gap. It presents the general societal background for Swedish in Finland and some of its characteristic differences from the Swedish standard. In addition, two studies which explore the pragmatic differences are presented: a study of speaker attitudes to forms of address and a conversation analytic study of expressions of criticism in teacher-student encounters.
