Rotwelsch

Also, in some southwestern and western locales in Germany, where travelling peoples were settled, many Rotwelsch terms have entered the vocabulary of the vernacular, for instance in the municipalities of Schillingsfürst and Schopfloch.

Some Rotwelsch- and Yenish-speaking vagrant communities also exist in Switzerland due the country's neutral status during World War Two.

[6] Josef Ludwig Blum from Lützenhardt (Black Forest) wrote from war prison: "[E]s grüßt Dich nun recht herzlich Dein Mann, viele Grüße an Schofel und Bock.

They were instead code words, Schofel ("bad") and Bock ("hunger"), which hid the message that the prisoners weren't doing well, and that they were starving.

[8] An example of Rotwelsch is found in Gustav Meyrink's Der Golem and reads as follows: An Beindel von Eisen recht alt.
