Distribution of the Germanic languages in Europe.
In many Swedish and Norwegian dialects, the r sound was assimilated to following dental consonants (l, n, s, t, d) to create a series of retroflex consonants. These sounds, which are produced by curling the tip of the tongue toward the hard palate, are characteristic of the dialects spoken in major urban centers such as Oslo and Stockholm.1
