Highest Alemannic German in the context of "Zermatt"

The German-speaking part of Switzerland (German: Deutschschweiz [ˈdɔʏtʃ.ʃvaɪts] ; French: Suisse alémanique; Italian: Svizzera tedesca; Romansh: Svizra tudestga) comprises about 65 percent of Switzerland (North Western Switzerland, Eastern Switzerland, Central Switzerland, most of the Swiss Plateau and the greater part of the Swiss Alps).

The variety of the German language spoken in Switzerland is called Swiss German which refers to any of the Alemannic dialects and which are divided into Low, High and Highest Alemannic. The only exception within German-speaking Switzerland is the municipality of Samnaun where an Austro-Bavarian dialect is spoken.

Swiss German (Standard German: Schweizerdeutsch, Alemannic German: Schwiizerdütsch, Schwyzerdütsch, Schwiizertüütsch, Schwizertitsch Mundart, and others; Romansh: tudestg svizzer) is any of the Alemannic dialects spoken in the German-speaking part of Switzerland, and in some Alpine communities in Northern Italy bordering Switzerland. Occasionally, the Alemannic dialects spoken in other countries are grouped together with Swiss German as well, especially the dialects of Liechtenstein and Austrian Vorarlberg, which are closely associated to Switzerland's.

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.

Walser German (German: Walserdeutsch) and Walliser German (Walliserdeutsch, locally Wallisertiitsch) are a group of Highest Alemannic dialects spoken in parts of Switzerland (Valais, Ticino, Grisons), Italy (Piedmont, Aosta Valley), Liechtenstein (Triesenberg, Planken), and Austria (Vorarlberg).

Usage of the terms Walser and Walliser has come to reflect a difference of geography, rather than language. The term Walser refers to those speakers whose ancestors migrated into other Alpine valleys in medieval times, whereas Walliser refers only to a speaker from Upper Valais – that is, the upper Rhone valley. In a series of migrations during the Late Middle Ages, people migrated out of the Upper Valais, across the higher valleys of the Alps.
