Dialects of Norwegian

The Norwegian dialects are commonly divided into 4 main groups, 'Northern Norwegian' (nordnorsk), 'Central Norwegian' (trøndersk), 'Western Norwegian' (vestlandsk), and 'Eastern Norwegian' (østnorsk). Sometimes 'Midland Norwegian' (midlandsmål) and/or 'South Norwegian' (sørlandsk) are considered fifth or sixth groups.

The dialects are generally mutually intelligible, but differ significantly with regards to accent, grammar, syntax, and vocabulary. If not accustomed to a particular dialect, even a native Norwegian speaker may have difficulty understanding it. Dialects can be as local as farm clusters, but many linguists note an ongoing regionalization, diminishing or even elimination of local variations.

Normalized speech, following the written languages Bokmål and Nynorsk or the more conservative Riksmål and Høgnorsk, is not in common use, except in parts of Finnmark (where the original Sami population learned Norwegian as a second language), in certain social groups in the major urban areas of Norway, in national broadcasting, and in courts and official decrees.

Owing to geography and climate, Norwegian communities were often isolated from each other until the early 20th century. As a result, local dialects had a tendency to be influenced by each other in singular ways while developing their own idiosyncrasies. The community of Oppdal, for example, has characteristics in common with coastal dialects to the west, the dialects of northern Gudbrandsdalen to the south, and other dialects in Sør-Trøndelag from the north. The linguist Einar Haugen documented the particulars of the Oppdal dialect, and the writer Inge Krokann used it as a literary device. Other transitional dialects include the dialects of Romsdal and Arendal.
