So far we 
              have learned the present imperative forms  
              ख़रीदो(familiar), and 
               
              ख़रीदिये (polite). 
              When we want to ask someone to do something in the future, then 
              we may use the future imperative forms: 
             
              A. Familiar future imperative = infinitive, e.g:  
              ख़रीदना, आना 
            
              
                 
                  |  
                      
                      तुम मेरे घर 
                      कल आना।  | 
                   
                     Come 
                      to my house tomorrow:  | 
                 
              
             
             
                
            B. Polite 
              future imperative = regular polite imperative +third person sing 
              future ending, e.g.:  
              ख़रीदियेगा, 
              आइयेगा 
            
              
                 
                  |  
                      
                      आप मेरे घर 
                      कल आइयेगा।  | 
                   
                     Please 
                      come to my house tomorrow.  | 
                 
              
             
            Note: Both 
              future imperatives are always masculine third person singular; 
              they never change under any condition.
