What is "anderster"

Anderster, or andɐrstɐr as it says on the album cover, is a studio album by the German punk rock band Wizo, released 1 November 2004. When announcing the album, the band offered the English translation of "differenter". The band explains on the back cover of the album that the album was supposed to be different but instead turned out even "differenter".

The word anderster is an artificial construction based on the German word anders, which means "different". The word anderster does not officially exist within the German language and could be considered a neologism or a grammatically incorrect construction. Because anders is an adverb, it is not considered proper to use in a comparative describing a noun. The proper adjective form of anders is andersartig, which changes to andersartiger with the proper comparative inflection, meaning "more different".
