It is Monday, five past nine. You are filling your cup in the office kitchen, and a coworker, Mia, turns around: Did you go anywhere this weekend?
You know the answer. You went to your sister’s house. But a second problem arrives right behind the first one. When you want to ask Mia the same question, your mouth starts to build it from the answer: Did you went…? The question sounds almost right, and it is not.
This page follows one short Monday conversation, line by line. Each line shows one small rule, and all the rules are the same rule: after did or didn’t, the verb is plain. Paul and Emily, the hosts of an episode about talking about yesterday, give it a picture: “Did comes first, and the verb goes home.”
(Quotes in curly marks are from that episode. Sentences in italics are written for this page. The conversation with Mia is written for this page too.)
Monday at 9:05: six lines, four plain verbs
Read the conversation once, and look only at the verbs.
Mia: Did you go anywhere this weekend?
You: Yes, I did. I went to my sister’s house.
Mia: Nice! Did you take the train?
You: No, I didn’t. I took the bus.
Mia: What did you eat?
You: We ate rice and fish. I didn’t cook. My sister did.
Mia: Did she make dessert?
You: Yes, she did. She made a cake.
The four verbs in Mia’s questions are go, take, eat, make. They are all plain. The verbs in your answers are went, took, ate, made. They are the past forms, and they appear only when you say what happened. In your negative sentence, I didn’t cook, the verb is plain again.
So there are two places for a plain verb (the question and the negative) and one place for the past form (the true sentence). Keep that map in your head, and the rest of this page is practice.
The verb goes home
Paul says to think of a past verb as a person on a trip: “Went is go on a trip. Ate is eat on a trip.” And Emily adds: “when did comes into the sentence, the trip is over.” Paul finishes the picture: “The verb goes home. It goes back to its simple form.”
Here is the same idea as a table. Read each row from left to right.
| What happened | The question | The negative |
|---|---|---|
| I went to the market. | Did you go to the market? | I didn’t go to the market. |
| She took the bus. | Did she take the bus? | She didn’t take the bus. |
| We ate lunch. | Did you eat lunch? | We didn’t eat lunch. |
| He made tea. | Did he make tea? | He didn’t make tea. |
| They bought bread. | Did they buy bread? | They didn’t buy bread. |
| I saw the email. | Did you see the email? | I didn’t see the email. |
Why does it work this way? Because did is already the past. One past mark per sentence is enough. If you put did and went together, you say “past” twice, and English does not do that.
The same holds for regular verbs. I cooked becomes Did you cook? and I didn’t cook. The -ed goes home along with the irregular forms.
Yes, I did. No, I didn’t: answers that stop in two words
When Mia asks Did you take the train?, you do not need a long answer. The episode says it plainly: “Short answers are perfect here. Yes, I did. No, I didn’t.” A short answer does not repeat the verb at all, so there is nothing to get wrong.
- Did you finish your homework? Yes, I did.
- Did he have the same book? Yes, he did. (the episode’s sentence)
- Did anyone eat it? My neighbor did. (also from the episode)
- Did you add sugar? No, I didn’t.
One more rule hides here: the short answer uses the same helper as the question. A did question gets a did answer. Did you go? Yes, I do is a mix-up of a past question and a present answer.
A short answer is the safe start. A good answer adds one true detail: Yes, I did. I went to my sister’s house. Say did, then a past form for the detail.
What did you eat? Question words go in front
The episode’s role play has five questions for you to answer. Look at where did sits:
- Where did you go?
- What did you eat?
- How did you feel at the end of the day?
The question word goes first, then did, then the subject, then the plain verb. Add Who did you see? and Why did you stop? and you have the family.
For the answer, you do not need did at all. Where did you go? I went to a café. The question carries the plain verb; the answer carries the past form.
When the verb is be: was and were do not need did
There is one place where did stays out. When the verb is be, the past forms are was and were, and they make their own questions and negatives. Paul: “We use was with I, he, she, and it.” Emily: “And we use were with you, we, and they.”
- How was your weekend? (the episode’s opening question for the office role play)
- Were you at home on Sunday? No, I wasn’t.
- The streets were busy. The streets weren’t busy.
Do not put was in front of another past verb. In the quiz Paul fixes “I was go to work by bus.” with “I went to work by bus. We don’t need was here. Just went.”
Three mistakes to catch before you speak
- A past form after did: Did you went? Did you saw him? The fix: Did you go? Did you see him?
- A past form after didn’t: I didn’t saw the email. The fix: I didn’t see the email. Paul’s note in the quiz: “Didn’t sends the verb home, too.”
- A present answer to a past question: Did you go? Yes, I do. The fix: Yes, I did.
If you say a sentence and are not sure, find the word did or didn’t. Then look at the next verb. If it ends in -ed or looks like a past form (went, saw, ate), send it home.
Three jobs for your turn: pick the verb, build the question, answer for yourself
1. Pick the verb
Choose the right word. The answers follow.
- Did you (see / saw) Mia on Monday?
- I didn’t (take / took) the train.
- We (ate / eat) rice for dinner.
- Did she (bought / buy) the bread?
- He didn’t (called / call) me back.
- (Were / Did) you at home yesterday?
Answers
- see (after did, the verb is plain).
- take (after didn’t, the verb is plain).
- ate (a true sentence, so the past form).
- buy (after did, plain).
- call (after didn’t, plain).
- Were (the verb is be, so no did).
2. Build the question and the negative
Use the pattern from the table. The answers follow.
- I watched a movie. → question: ____ / negative: ____
- She wrote a message. → question: ____ / negative: ____
- They played football. → question: ____ / negative: ____
- You bought a coat. → question: ____ / negative: ____
Answers
- Did you watch a movie? / I didn’t watch a movie.
- Did she write a message? / She didn’t write a message.
- Did they play football? / They didn’t play football.
- Did you buy a coat? / You didn’t buy a coat. (or I didn’t buy a coat if you are the speaker)
3. Answer for yourself
Answer these three questions about your own yesterday, first with a short answer, then with one more detail. A model follows.
- Did you cook yesterday?
- Where did you go?
- What did you eat for lunch?
A model answer
- No, I didn’t. I ate at my desk.
- I went to the supermarket after work.
- I ate soup and bread.
Your answers will be different. The check is the same: after did and didn’t, is the verb plain?
The pattern on one card
- A true sentence uses the past form: I went, she took, we ate.
- A question starts with Did, and the verb is plain: Did you go? Did she take it?
- A negative uses didn’t, and the verb is plain: I didn’t go. She didn’t take it.
- A short answer uses did: Yes, I did. No, I didn’t.
- A question word goes in front: Where did you go? What did you eat?
- With be, use was and were, with no did: How was your weekend? We weren’t there.
Hear it in a real conversation
The rules on this page come from one long, friendly episode about talking about yesterday, with a missed train stop and a banana bread without sugar.
