This article describes the language. For the beer see Bönnsch (beer).
Bönnsch is the Ripuarian dialect spoken in central Bonn, Germany. Bönnsch (also called Bönnsch Platt) is closely related to Kölsch, but it has a different melody and a slightly different vocabulary. Bönnsch is described as having a more singsong sound than Kölsch. An obvious phonologic distinction between the two is that Kölsch contrasting to Standard German uses [ʃ] in most places where German has [ç], while Bönnsch is using [ç] in most places where German has [ʃ].
