We use the Past Simple to talk about actions, states, or events that started and finished at a specific time in the past. It is one of the first tenses learners meet, and it stays one of the most frequently used tenses in everyday English.
- She moved to Berlin in 2019. (a finished action at a stated time)
- We watched a great film last night. (a completed event, finished before now)
Forming the Past Simple
Most verbs are regular: you simply add -ed to the base form. A large group of common verbs, however, are irregular and change form completely, so they need to be learned individually.
Regular Verbs
- I walked to school every day when I was young. (walk → walked)
- They played tennis on Saturday. (play → played)
- Spelling note:
study→studied,stop→stopped(consonant doubled),like→liked(drop the silent -e).
Irregular Verbs
- I went to the market yesterday. (go → went)
- She saw an old friend at the station. (see → saw)
- We had breakfast at seven. (have → had)
There is no shortcut for irregular verbs — go/went, see/saw, eat/ate, buy/bought and dozens more simply need to be memorised through repeated exposure and practice.
Negative Sentences
Negatives are formed with the auxiliary did not (or didn't) plus the base form of the verb, regardless of whether the verb is regular or irregular.
- I didn't finish the report on time. (not "didn't finished")
- He didn't go to the party. (not "didn't went")
Questions
Questions are formed by putting did before the subject, followed again by the base form of the verb.
- Did you enjoy the concert?
- What time did the train arrive?
Time Expressions
The Past Simple is almost always used together with, or implies, a specific past time reference, even when that reference is only understood from context.
- yesterday, last week, last year: We travelled to Rome last summer.
- ago: She graduated three years ago.
- in + past year: The company was founded in 1998.
Summary Table
| Form | Structure | Example |
|---|---|---|
| Affirmative | subject + verb-ed / irregular past | She finished the exam. |
| Negative | subject + didn't + base verb | She didn't finish the exam. |
| Question | Did + subject + base verb? | Did she finish the exam? |
Tip: If a sentence has did, the main verb always goes back to its base form — never double up the past tense. "Did you went?" is a very common learner error; the correct form is "Did you go?"
Common Mistakes
-
Using the past form after "did":
Incorrect: Did you went to the meeting?
Correct: Did you go to the meeting? -
Forgetting "didn't" and just adding "not" to the past verb:
Incorrect: I not went to the shop.
Correct: I didn't go to the shop. -
Regularising an irregular verb:
Incorrect: She buyed a new car.
Correct: She bought a new car.

Frequently Asked Questions
What is the Past Simple tense used for?
The Past Simple is used for actions, states, or events that started and finished at a specific, definite time in the past, such as "She moved to Berlin in 2019" or "We watched a film last night."
How do you form the Past Simple with regular verbs?
Add -ed to the base form of a regular verb, for example walk → walked or play → played. Spelling changes apply in some cases, such as study → studied and stop → stopped.
How do you form negative sentences in the Past Simple?
Use did not (or didn't) followed by the base form of the verb, as in "I didn't finish the report" — never "didn't finished."
How do you form questions in the Past Simple?
Put did before the subject, followed by the base form of the verb: "Did you enjoy the concert?" The main verb never takes a past ending after "did."
What are irregular verbs in the Past Simple?
Irregular verbs do not follow the regular -ed pattern and change form completely, such as go → went, see → saw, and have → had. These forms must be memorised individually.
What time expressions go with the Past Simple?
Common time expressions include yesterday, last week, last year, ago (as in "three years ago"), and specific past years, as in "The company was founded in 1998."
What is a common mistake with irregular verbs in the Past Simple?
A common mistake is "regularising" an irregular verb, for example saying "She buyed a new car" instead of the correct irregular form, "She bought a new car."
Can the Past Simple be used without a stated time expression?
Yes, as long as the time is clear from context, for example when answering a question: "When did you call her?" "I called her this morning." The finished, specific-time meaning is still present.
What is the difference between "didn't go" and "didn't went"?
"Didn't go" is correct because the auxiliary did already carries the past tense, so the main verb stays in its base form. "Didn't went" is incorrect because it doubles the past marking.
How is the Past Simple different from the Past Continuous?
The Past Simple describes a completed action viewed as a whole ("I ate dinner at seven"), while the Past Continuous describes an action in progress at a point in the past ("I was eating dinner when the phone rang").
