German is an official language in Austria, Belgium, Germany, Liechtenstein, Luxembourg and Switzerland. German is also spoken in the Italian province Bolzano-Bozen, the Czech Republic, Denmark, Hungary, Namibia, Romania and Slovakia. Germany accounts for a large part of the native German speaking community followed by Austria and Switzerland; people in the German part of Switzerland communicate using standard German with a significant number of exceptions called Helvetisms. Helvetisms are distinct characteristics of Swiss German that are not to be confused with dialects, which only span certain geographic areas.
Helvetisms manifest themselves in vocabulary and pronunciation, yet sometimes the deviation of Standard German is reflected in syntax and orthography as well. The most significant difference of Swiss German versus Standard German is the lack of “ß” (Eszett) in the official alphabet; instead “ss” is used such as in grüßen (to greet), which you find as grüssen in Swiss Standard German — the blend of standard German and Helvetisms.
