To form negative sentences and questions in the Past Simple, we use the auxiliary verb did. This is a key rule for most verbs in English. For negative statements, you combine did with not (or didn’t) and the base form of the main verb. For questions, did comes before the subject, followed by the base form of the main verb.
This structure is the same for all subjects (I, you, he, she, it, we, they), making it quite straightforward once you understand the pattern. Remember, the main verb always returns to its base form because did already carries the past tense information. The only exception is the verb to be, which uses was or were for negatives and questions without did.
When Do We Use the Past Simple?
We use the Past Simple to talk about actions or situations that started and finished in the past. These events are completed and have a clear time reference, even if it’s not always stated.
- I went to Greece last summer. (The action of going is finished.)
- She finished her homework an hour ago. (The action of finishing is completed.)

How Do We Form Past Simple Negative Sentences?
To make a sentence negative in the Past Simple, we use the auxiliary verb did plus not, followed by the base form of the main verb. This structure is the same for all subjects.
- Structure: Subject + did not / didn't + base form of verb
- I did not go to the party. (Formal)
- You didn't study for the exam. (Informal)
- They didn't like the movie.
- He didn't finish his dinner.
Remember to always use the base form of the main verb (e.g., go, study, like, finish), not the past simple form (e.g., went, studied, liked, finished).
How Do We Ask Questions in the Past Simple?
Forming questions in the Past Simple also uses the auxiliary verb did. The main verb always returns to its base form.
Yes/No Questions
For questions that can be answered with 'yes' or 'no', did comes at the beginning of the sentence.
- Structure: Did + subject + base form of verb?
- Did you call me yesterday?
- Did she enjoy the concert?
- Did they arrive on time?
Wh- Questions
For questions that ask for specific information (who, what, where, when, why, how), the Wh- word comes first, followed by did.
- Structure: Wh- word + did + subject + base form of verb?
- Where did you go on holiday?
- What did he say?
- When did they leave?
- Why did she cry?
What About the Verb 'To Be' in the Past Simple?
The verb to be (was/were) is special. It does not use did for negatives or questions. Instead, you add not directly to was or were, or you invert the subject and verb for questions.
- Positive: I was happy. They were busy.
- Negative: I was not happy. / I wasn't happy. They were not busy. / They weren't busy.
- Question: Was I happy? Were they busy?
| Base Form | Past Simple |
|---|---|
| go | went |

| see | saw |
| make | made |
| do | did |
| eat | ate |

Many learners make these common mistakes when forming Past Simple negatives and questions:
- Using the past form of the main verb: Incorrect: I didn't went. Correct: I didn't go. (The did already shows the past tense.)

- Using did with the verb to be: Incorrect: He didn't was here. Correct: He wasn't here.
Frequently asked questions
Is the Past Simple negative the same for all subjects?
Yes, the structure subject + did not / didn't + base form of verb is used for all subjects (I, you, he, she, it, we, they).
Do I use 'did' with 'was' or 'were'?
No, you do not use did with was or were. For the verb to be, you form negatives with wasn't/weren't and questions by putting was/were before the subject.
Why is it important to use the base form of the verb with 'did'?
It's important because the auxiliary verb did already carries the past tense information. The main verb does not need to be in its past form again.
How does this help me in English exams?
Understanding Past Simple negatives and questions is crucial for many B1 exam tasks, such as answering interview questions about past experiences or writing emails and stories about completed events.
