How to answer negative questions in English without confusing people

For these common questions, practise the answer that matches the facts:

Question	If the action or state is true	If it is not true
Aren't you ready?	Yes, I am. I'm ready.	No, I'm not ready yet.
Didn't you save the document?	Yes, I did. I saved it.	No, I didn't save it.
Haven't you received the code?	Yes, I have. I've received it.	No, I haven't received it.
Can't you open the folder?	Yes, I can open it.	No, I can't open it.

These are practice answers, not a requirement to repeat every sentence in full. Once the meaning is clear, "Yes, I did" may be enough. If there is any doubt, name the action again.

The British Council's short-answer lesson explains the usual pattern of repeating the first verb in the question's verb phrase. That gives you the useful pairs "have / haven't," "did / didn't" and "can / can't."

Keep the tense connected to the question. "Didn't you save it?" asks about a past action. "I don't save it" describes a different idea, such as a habit. If you lose track of the short form, use a complete statement: "I saved the document before lunch."

It is tempting to memorise one universal rule for every question containing not. Actual English conversation is more complicated than that.

In his research presentation How to answer a negative question, linguist Anders Holmberg discusses English cases where a single yes can receive different interpretations. The wording and position of the negative matter. His examples also show why adding the verb can make the intended positive meaning explicit.

For everyday speaking, you do not need the technical analysis. Use it as a reason to make your answer complete when the result matters. "The booking is confirmed" communicates more than an isolated "yes" after "Is the booking not confirmed?"

This is especially useful when people are deciding what to do next. Your goal is not to prove that your yes was grammatically defensible. It is to make sure both people understand the same status.

Someone may sound as though they expected an action to be finished. You can still say it is unfinished, or that you do not know.

Question: "Hasn't Maya uploaded the slides?"

Possible answer: "I haven't checked the folder. I'll look now."

That is more accurate than saying "No, she hasn't" simply because you have not seen them. Not knowing about an upload is different from knowing it did not happen.

You may also need to separate two actions:

Question: "Haven't you sent the application?"

Answer: "I've completed it, but I haven't submitted it."

Now the listener knows that completed does not mean sent. Do not squeeze a partly finished task into a yes that hides the unfinished part.

Imagine this fictional exchange:

Alex: "Didn't you book the room?"

You: "Yes."

Alex: "OK, I'll stop looking for a room."

You meant to agree that the room had not been booked. Alex understood that you had booked it. Correct the fact immediately:

"Sorry, I meant that I haven't booked it. We still need a room."

You do not need a long explanation of why the misunderstanding happened. State the current situation and the action still needed. If the misunderstanding concerned the wrong room or date instead, use the guide to correcting a detail in English.

As the listener, avoid asking another negative question to repair the first one. Try "Is the room booked, or do we still need to book it?" The alternatives make the missing information visible.

Work with a partner. One person asks the question; the other reads the private fact and answers. The questioner must then say what they will do next.

Question	Private fact for the person answering
Haven't you sent the agenda?	You sent it to Alex, but not to the whole group.
Didn't you reserve the projector?	You asked whether it was available. Nobody confirmed a reservation.
Can't you open the shared folder?	You can open the folder, but one file inside it will not open.
Isn't the meeting cancelled?	You have heard a rumour but have not received a cancellation message.

Possible answers include:

• "I've sent the agenda to Alex only. The rest of the group still needs it."
• "I asked about the projector, but I don't have a confirmed reservation."
• "I can open the folder. It's the budget file that I can't open."
• "I don't know whether it's cancelled. We need to check with the organiser."

The questioner now describes a next step, such as checking the reservation rather than assuming the projector is secured. Compare that action with the private fact. If it depends on a mistaken assumption, clarify your answer and try again.

For another round, change one fact without changing the question. Perhaps the projector reservation is now confirmed. Your answer should change because the situation changed, not because you memorised a response to "Didn't you..."

If you need more practice asking someone what they mean, use the English clarification exercise. In this task, the success check is narrower: can your partner correctly report what is done, what is unfinished and what is unknown?
