The simple past (also called past simple, past indefinite or preterite) is a verb tense which is used to show that a completed action took place at a specific time in the past. The simple past is also frequently used to talk about past habits and generalizations.
The simple past is formed using the verb + ed. In addition, there are many verbs with irregular past forms.
Questions are made with didand negative forms are made with did not.
Most verbs conjugate by adding -ed like the verb “wait” below.
| Positive | Negative | Question |
| I waited. | I did not wait. | Did I wait? |
| You waited. | You did not wait. | Did you wait? |
| We waited. | We did not wait. | Did we wait? |
| They waited. | They did not wait. | Did they wait? |
| He waited. | He did not wait. | Did he wait? |
| She waited. | She did not wait. | Did she wait? |
| It waited. | It did not wait. | Did it wait? |
Many verbs, such as “have,” take irregular forms in the simple past. Notice that you only use the irregular verbs in statements. In negative forms and questions, “did” indicates simple past.
| Positive | Negative | Question |
| I had. | I did not have. | Did I have? |
| You had. | You did not have. | Did you have? |
| We had. | We did not have. | Did we have? |
| They had. | They did not have. | Did they have? |
| He had. | He did not have. | Did he have? |
| She had. | She did not have. | Did she have? |
| It had. | It did not have. | Did it have? |
The verb “be” is also irregular in the simple past. Unlike other irregular verbs, there are two simple past forms: “was” and “were.” It also has different question forms and negative forms. Always remember that you DO NOT use “did” with the verb “be” in the simple past.
| Positive | Negative | Question |
| I was. | I was not. | Was I? |
| You were. | You were not. | Were you? |
| We were. | We were not. | Were we? |
| They were. | They were not. | Were they? |
| He was. | He was not. | Was he? |
| She was. | She was not. | Was she? |
| It was. | It was not. | Was it? |

Use the simple past to express the idea that an action started and finished at a specific time in the past. Sometimes, the speaker may not actually mention the specific time, but they do have one specific time in mind.
Examples:

We use the simple past to list a series of completed actions in the past. These actions happen 1st, 2nd, 3rd, 4th, and so on.
Examples:

The simple past can be used with a duration which starts and stops in the past. A duration is a longer action often indicated by expressions such as: for two years, for five minutes, all day, all year, etc.
Examples:

The simple past can also be used to describe a habit which stopped in the past. It can have the same meaning as “used to.” To make it clear that we are talking about a habit, we often add expressions such as: always, often, usually, never, when I was a child, when I was younger, etc.
Examples:

The simple past can also be used to describe past facts or generalizations which are no longer true. As in USE 4 above, this use of the simple past is quite similar to the expression “used to.”
