Now by ordinary German word building rules, 'kölnisch' means 'belonging to Cologne', 'related to Cologne', 'in Cologne', 'from Cologne'—as in 'kölnisch Wasser' ("Eau de Cologne"). The word 'kölnisch', or 'köllesch', shortened to 'kölsch' in local tongue, became a shorthand noun for the local beer and the local language, or dialect.
