What is "manisch"

Manisch refers either to a dialect of rotwelsch (especially in the vicinity of greater Gießen, Germany) or a speaker thereof (plural: Manische or Manen). The term Manisch however, is also understood primarily throughout much of the German state of Hesse and parts of the Rhineland-Palatinate to refer to the Manisch/ Jenisch (alternatively "gypsy") elements of their vernacular. Several words are recognisably derived from Yiddish (e.g. malocho, work) or Romany (e.g. pani, water).
