Usage notes

 * The expression is rare in actual usage. Even in thick Ripuarian dialect one generally uses the plain and simple word ("cheese sandwich"). However, Halve Hahn is occasionally used as a shibboleth among Rhineland people and can be found on the menus of traditional Colognian pubs (as a humorous knowledge test for foreigners).
 * The term is either uninflected, e.g. (accusative) den Halve Hahn, or the first part behaves like a normal German adjective, thus den Halven Hahn, and so on.
