✅I want to assure you that the package will arrive.
💡'ensure' means to make something certain; 'assure' means to remove someone's doubts by telling them something is true.
❌Please ensure me that the doors are locked.
✅Please ensure that the doors are locked.
💡'ensure' does not take an indirect object. The thing made certain, not the person, is the direct object.
