While the Swedish negator inte may be doubled in a final clause-external position, in both
standard Swedish and dialects, many dialects also allow a final, clause-internal particle (e, i or
ai) in negated clauses. FNPs occur in a coherent area around the Baltic Sea, and in contrast with doubling
negation, they are possible both after both inte and aldrig ‘never’. FNPs are also used in
questions and exclamations, contexts that disallow doubling negation. These particles may have developed from the former Swedish
negator ej or from the common inte. An argument for the former alternative is that other
dialectal phenomena that spread from central Sweden during the late Middle Ages have approximately the same geographic
distribution. In the final section of the paper, some typological consequences and implications are discussed. Furthermore, it is
argued that syntactic studies of non-standard varieties may reveal new insights of typological relevance.
