• Passive Causatives: Have

• 
• We can also use have with the passive causative. 

  
  

  subject + have + object + past participle

  - Sara has her groceries delivered.
  

  (Sara doesn't deliver the groceries, someone else does it for her.)

  
  

  Be careful! In a normal sentence, the subject does the action. In the causative, someone else does the action.

  -Sara delivers groceries. = Sara performs the action.

  -Sara has her groceries delivered. = Someone else performs the action.
