標準德語
Today all formal writing, newspapers, books and much informal writing is done in Swiss Standard German, which is usually called "Schriftdeutsch" (written German). Certain dialectal words are accepted regionalisms in Swiss Standard German and are also sanctioned by the Duden, e.g., "Zvieri" (afternoon snack). Swiss Standard German is virtually identical to Standard German as used in Germany, with most differences in pronunciation, vocabulary, and orthography. For example, Swiss Standard German always uses a double s ("ss") instead of the eszett ("ß").
