Linguistically, Alemannic is divided into Low, High and Highest Alemannic, varieties all of which are spoken both inside and outside Switzerland. The only exception within German-speaking Switzerland is the municipality of Samnaun where a Bavarian dialect is spoken. The reason "Swiss German" dialects constitute a special group is their almost unrestricted use as a spoken language in practically all situations of daily life, whereas the use of the Alemannic dialects in other countries is restricted or even endangered.[citation needed]
