Definition / Explanation
Perfect passive forms combine the idea of completion with passive focus. They are used when we want to show that something has already been done to a person or thing, often before another point in time. The main forms are has/have been + past participle and had been + past participle. These forms are useful in formal writing, reports, and explanations where results matter more than the agent. They help speakers describe completed processes while keeping attention on the object, result, or affected subject.
Key Rules
- Present perfect passive: has/have been + past participle.
- Past perfect passive: had been + past participle.
- Use it when the action is completed and the receiver remains the focus.
- Add the agent with by only if it is important.
- Do not confuse has been doing with has been done. One is active continuous, the other is passive perfect.
Examples
