How do you change imperative sentences (commands) from active to passive?

In one line

The rule

To change an imperative sentence from active to passive, use "Let" + object + be + past participle (V3) + (by + agent).

Formula: Let + object + be + V3 + (by + agent)

• V3 means the third form of the verb (past participle), like "done", "eaten", "opened".

Let's understand it simply

Imagine your mother says, "Shut the window." This is a command (imperative sentence). In active voice, you are told to do the action. In passive voice, the focus shifts to the window — what should happen to it. So, it becomes, "Let the window be shut." Now, it does not matter who shuts it, just that it should be done.

How it works

1. Find the object (the thing the action is done to).
2. Start the passive sentence with "Let".
3. Add the object after "Let".
4. Use "be" + past participle (V3) of the verb.
5. If you want to say who should do it, add "by" + person (optional).

The story behind it

English teachers and grammarians noticed that commands (imperatives) are special. They often do not mention who should do the action. To make them passive, a special way was needed. The "Let...be..." form became the standard, making it clear what should happen, not who should do it.

Where you see it in real life

• Classroom instructions: "Open your books." → "Let the books be opened."
• Kitchen: "Boil the water." → "Let the water be boiled."
• Cricket coach: "Catch the ball!" → "Let the ball be caught!"
• Notice board: "Submit your forms." → "Let the forms be submitted."
• Exam hall: "Write your name." → "Let your name be written."
• Home: "Clean the room." → "Let the room be cleaned."

Why it matters

• Used in formal instructions and notices.
• Helps you understand and write clear rules or guidelines.
• Important for exams and official writing.
• Makes your English sound more polished and correct.

Worked example

Let's change "Close the door." to passive:

Given: Active imperative = Close the door.
Step 1: Find the object      the door
Step 2: Start with "Let"     Let the door
Step 3: Add "be" + V3        Let the door be closed.
Step 4: (Agent, if needed)   Let the door be closed by you. (usually not needed)
Answer: Let the door be closed.

Common mistakes

• Forgetting to use "Let": Passive imperatives almost always start with "Let".
• Using the wrong verb form: Always use the past participle (V3), not present or past.
• Adding unnecessary agents: Usually, you do not need to say "by you"; only add it if it is important.

Remember it

To change a command to passive, start with "Let", then the object, then "be" + V3.
