* In common language 
                          the Genitive of the substantival possessive pronoun is 
                          not used. There is another form of a possessive that 
                          could be used (der deinige, die deinige, das deinige), 
                          but it sounds really antiquated. If you want to form 
                          a Genitive of deine 
                          it is mostly done like in English.  
                        
                          
                            
                                
                                    |
