A Structure (Regular & Irregular Verbs)
The past simple is used to talk about completed actions or events that happened at a finished time in the past. Regular verbs usually end in -ed, while irregular verbs have different past forms that must be learned.
| Regular Verb | Irregular Verb |
|---|---|
| walk → walked | go → went |
| work → worked | eat → ate |
| play → played | see → saw |
| visit → visited | buy → bought |
Tip: The words yesterday, last night, last week, last month, last year, ago, and in 2024 often tell you to use the past simple. Remember that regular verbs usually add -ed, but irregular verbs have special past forms that you need to memorize.
B Spelling Rules for Regular Verbs (-ed)
Most regular verbs form the past simple by adding -ed. However, some verbs follow special spelling rules before adding -ed. Learning these patterns will help you spell regular verbs correctly.
| Rule | Example |
|---|---|
| Most verbs | work → worked visit → visited |
| Verbs ending in e (add -d) | live → lived move → moved |
| Consonant + y (change y → i) | study → studied carry → carried |
| Short vowel + consonant (double the final consonant) | stop → stopped plan → planned |
Tip: These spelling rules apply only to regular verbs. Irregular verbs do not follow these patterns. For example:
✓ study → studied
✓ stop → stopped
✗ study → studyed
✗ stop → stoped
C Positive Sentences
Use the past simple to describe completed actions or events that happened at a finished time in the past. In positive sentences, use the past tense form of the main verb. Do not use did in positive statements.
- I visited my grandparents last weekend.
- She finished her homework before dinner.
- They went to the beach yesterday.
- We watched an interesting movie last night.
- He bought a new bicycle two weeks ago.
Tip: Positive sentences use only one past tense verb.
✓ She played soccer yesterday.
✓ They went home early.
✗ She did played soccer yesterday.
✗ They did went home early.
D Negative Sentences
Use did not or didn't to say that something did not happen or was not true in the past. When you use did, the main verb always stays in its base form. Do not use the past tense of the main verb after did.
- I didn't finish my homework last night.
- She didn't go to school yesterday.
- They didn't watch the movie.
- We didn't visit our grandparents last weekend.
- He didn't buy a new phone.
Tip: After did or didn't, always use the base form of the verb.

✓ They didn't arrive on time.
✗ She didn't ate breakfast.
✗ They didn't arrived on time.
E Yes/No Questions & Short Answers
To ask a yes/no question in the past simple, place did before the subject. The main verb always stays in its base form. Answer with Yes or No, followed by a short answer.
Yes, subject + did.
No, subject + didn't.
- Did you finish your homework?
Yes, I did. - Did she call you yesterday?
No, she didn't. - Did they visit the museum?
Yes, they did. - Did he buy a new laptop?
No, he didn't.
Tip: When asking questions with did, always use the base form of the verb.
✓ Did she finish her project?
✓ Did they arrive on time?
✗ Did she finished her project?
✗ Did they arrived on time?
F Wh- Questions
Use Wh- questions to ask for specific information about completed actions in the past. Common question words include who, what, where, when, why, and how. After the question word, use did, followed by the subject and the base form of the main verb.
- Where did you go last weekend?
I went to Banff. - When did she finish her project?
She finished it yesterday. - Why did they leave early?
Because they had another meeting. - How did he solve the problem?
He asked his teacher for help. - Who did you meet at the conference?

✗ Where did she went yesterday?
✗ Why did they left early?
G Time Expressions
The past simple is often used with time expressions that show an action happened at a finished time in the past. These words and phrases help you recognize when to use the past simple.
| Time Expression | Example |
|---|---|
| yesterday | We visited our grandparents yesterday. |
| last week / last month / last year | She started a new job last month. |
| ... ago | They moved here two years ago. |
| in + year | The company opened a new office in 2023. |
| this morning / this afternoon* | I called my doctor this morning. |
*Use the past simple when the time period has already finished.

✓ We watched a movie last night.
✓ She graduated in 2022.
✗ We have watched a movie last night.
✗ She has graduated in 2022.
