The German Alphabet consists of 26 letters and 3 Umlaute (Ä, Ö, Ü) and the grapheme β.
The Eszett (β) is not used in Switzerland and Liechtenstein. In colloquial language it has many names: sharp S (scharfes s), hunch S (Buckel-S) or curly S (Ringel-S).
But where does the name "Eszett" come from? The letter  "ſ" (long s) was a additional letter in the German alphabet in medieval times, a ligation between "ſ" and "z" became todays "β". Since 2017 there is also a capital version of this letter, but I have not seen any keyboards containing this option.
