A German Gentleman is referred to as 'HERR' in German, which is a four letter word. HERR is a title of respect used in German-speaking countries, equivalent to the English Mr. It is used for men of all ages and is also used to address someone formally. The title is often combined with a surname, a middle name, or a title of nobility. In some cases, it is used as a courtesy title for a man who has no other title.
