a few English words which are modern adoptions from Swiss German. The dishes müesli, and rösti have become English words, as did loess (fine grain), flysch (sandstone formation), kepi, landammann, kilch, , and putsch in a political sense. The term is sometimes explained as originating from Swiss German, while printed etymological dictionaries (e.g. the German Kluge or Knaurs Etymological Dictionary) derive it from Low German instead. Orthography History Written forms that were mostly based on the local Alemannic varieties, thus similar to Middle High German, were only gradually replaced by the forms of New High German. This replacement took from the 15th to 18th centuries to complete. In the 16th century, the Alemannic forms of writing were considered the original, truly Swiss forms, whereas the New High German forms were perceived as foreign innovations. The innovations were brought about by the printing press and were also associated with Lutheranism. An example of the language shift is the Froschauer Bible: Its first impressions after 1524 were largely written in an Alemannic language, but since 1527, the New High German forms were gradually adopted. The Alemannic forms were longest preserved in the chancelleries, with the chancellery of Bern being the last to adopt New High German in the second half of the 18th century. Today all formal writing, newspapers, books and much informal writing is done in Swiss Standard German, which is usually called (written German). Certain dialectal words are accepted regionalisms in Swiss Standard German and are also sanctioned by the Duden, e.g., (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). There are no official rules of Swiss German orthography. The orthographies used in the Swiss-German literature can be roughly divided into two systems: Those that try to stay as close to standard German spelling as possible and those that try to represent the sounds as well as possible. The so-called was developed by Eugen Dieth, but knowledge of these guidelines is limited mostly to language experts. Furthermore, the spellings originally proposed by Dieth included some special signs not found on a normal keyboard, such as instead of for or instead of for . In 1986, a revised version of the Dieth-Schreibung was published, designed to be typed with a
