Starckdeutsch
Starckdeutsch is an imagined language created by Matthias Koeppel, a German painter and poet and self-proclaimed Sprachkünstler. It exaggerates stereotypical traits of older stages of German and some modern dialects in an impressionistic way, rather than in a rigorously systematic fashion.
Matthias Koeppel started to write humorous poems in "Starckdeutsch" in 1972. A collection of them was published as Starckdeutsch. Sämtliche Gedichte in 1981.
