This paper looks at negation in Finnish dialects from a typological perspective. The focus is on standard negation, i.e. the negation of declarative verbal main clauses. The dialectal variation that Finnish shows in its negative construction is examined in the light of current typological knowledge of the expression of negation. Developmental trends connected to the micro-typological variation are also discussed, Finnish dialects are compared with related and neighbouring languages, and relevant theoretical and methodological issues relating to the meeting point of typology and dialectology are addressed.
