How to Form Questions in Simple Past
To ask questions in the simple past, we use the auxiliary verb 'did' at the beginning of the sentence. The main verb always stays in its base form (infinitive). This is the same for both regular and irregular verbs. The word order is important: Did + Subject + Base Verb + Rest of sentence?
Simple Past Questions — Examples
Simple Past — Questions
Yes / No Questions — Regular Verbs
Did she walk to school yesterday?
Statement: She walked to school yesterday. — "Did" moves to the front and the verb returns to its base form. The -ed ending is dropped.
Did they finish the project on time?
Statement: They finished the project on time. — "Did" carries the past tense marker, so "finish" stays in its base form, not "finished".
Did you call your parents last night?
Statement: You called your parents last night. — The auxiliary "did" applies to all subjects (I, you, he, she, it, we, they) — the form never changes.
Yes / No Questions — Irregular Verbs
Did he go to the party?
Statement: He went to the party. — Even though "went" is the irregular past form, we use the base form "go" after "did". Never write "Did he went…".
Did she see the new film?
Statement: She saw the new film. — "Saw" is the irregular past of "see", but in questions, "did" takes the past tense and the main verb reverts to "see".
Did they take a taxi to the airport?
Statement: They took a taxi to the airport. — The irregular past form "took" is replaced by the base form "take" once "did" is introduced.
Wh- Questions (Information Questions)
Where did you grow up?
The wh- word "where" comes first, followed by "did" + subject + base verb. This structure asks for specific information rather than a yes/no answer.
What did she eat for breakfast?
Statement: She ate a sandwich for breakfast. — "What" replaces the object "a sandwich". Word order is: What + did + subject + base verb.
When did they arrive at the hotel?
"When" asks about time. The structure follows the same pattern: wh- word + did + subject + base verb, regardless of the regular or irregular nature of the verb.
Why did he leave so early?
Statement: He left early because he was tired. — "Why" asks for the reason. "Leave" is the base form replacing the irregular past "left".
How much did you spend at the market?
Multi-word question phrases like "how much" still follow the same word order: question phrase + did + subject + base verb.
Subject Questions — When the Wh- Word Replaces the Subject
Who called you last night?
When "who" replaces the subject (e.g. Maria called you), we do not use "did". The verb keeps its past form: "called", not "Who did call you".
What happened at the meeting?
"What" is the subject here. Because we are asking about the subject itself, no auxiliary "did" is needed. The verb retains its simple past form: "happened".
Negative Questions
Didn't you hear the announcement?
"Didn't" is the contracted form of "did not". Negative questions often express surprise or seek confirmation. The main verb "hear" remains in its base form.
Did he not receive the email?
This is the uncontracted negative question form. "Not" comes after the subject and before the base verb. More formal than the contracted "Didn't he receive…?" form.
Examples
What to Remember
- Use 'did' at the beginning of the sentence to form simple past questions.
- The main verb always stays in its base form after 'did', never past tense.
- This rule applies to both regular and irregular verbs without any exceptions.
- The correct word order is: Did + Subject + Base Verb + Rest?
- Remember: 'did' carries the past tense, so the main verb stays in base form.
