The **Past Indefinite Tense** (also called the **Simple Past Tense**) is used to describe actions that happened at a specific time in the past. The past forms of verbs can be categorized into two types: **regular verbs** and **irregular verbs**.

Question words (also known as "wh-words") can be used with the past indefinite tense to ask about past actions or events. Here are some common question words used in the past indefinite tense:
1. What – used to ask about things, actions, or events.

3. When – used to ask about the time an event occurred.
4. Why – used to ask for reasons or explanations.
5. Who – used to ask about people (as the subject of the sentence).
6. How – used to ask about the manner or process of something.
These question words are followed by the auxiliary verb "did" (for regular and irregular verbs) and the base form of the main verb. The past indefinite tense indicates that the action is completed in the past.
The past indefinite tense (also called the simple past tense) is used to describe actions that were completed at a specific time in the past. When forming positive and negative sentences in this tense, the auxiliary verb "did" plays an important role.
