  'Have forms' are an important set in Auxiliary ( Helping) verbs. They can act independently as Main verbs and also help other main verbs.        

                                                                                                           

 How & When to use ‘have’ forms :  

1.   ‘Have forms’ are used as main verbs, independently, as substitute for the main verbs  possess, eat,               drink, get..etc. ( Simple present tense / Simple past tense )

  Ex:    I/we/you/they have a cycle .  
           I have my lunch at 1.30pm regularly

           He/ she/It has many toys.      
           He has his tea at 7am every day.

           I had my dinner at 8pm.        
          They had many books in school days.

           I shall have my lunch later. ( Simple Future)

2. As helping verb, used before V3, (Present/Past/Future Perfect Tense )         

   

   Ex : I have taken lunch just now.  
         We have received a message.

         She has just finished her work. 
         They have already got the results.

         We shall have arrived by that time.
         He will have attended the work.

·    Generally we avoid telling time in any Perfect Tense. We can use the signal words/ adverbs of time                 like just now, just then, recently, lately, already..etc.

3. As helping verb , used before  been+ ing   ( Present/Past/Future perfect continuous tenses )

         I/We/He/They had been working on that project.

        I/we/He/They will have been watching the cricket match.

•    ‘Have been’ verb form without main verb  is also used instead of the verbs   ‘ go, visit , exist ‘

                           I have been to Delhi many times.  She has been to London once.

                           He has been good.   It has been there over a long time.
