Sentence structure means arranging words in the correct order to make a clear and meaningful sentence. In Past Indefinite Tense, we use different structures to talk about completed actions in the past.

✅ 1. Affirmative Sentences (Positive)

These sentences tell us that an action happened in the past.

📌 Structure:
Subject + Verb (2nd form) + Object

✨ Examples:

• I played cricket.
• She went to school.
• They watched a movie.

💡 Explanation:
👉 We use the 2nd form of the verb (played, went, watched) to show past action.

👉 The 2nd form of the verb is used only in Past Indefinite Tense affirmative sentences.

❌ 2. Negative Sentences

These sentences tell us that an action did not happen in the past.

📌 Structure:
Subject + did not (didn’t) + Verb (1st form) + Object

✨ Examples:

• I did not play cricket.
• She did not go to school.
• They did not watch a movie.

💡 Explanation:
👉 After did not, we always use the 1st form of the verb (play, go, watch).

❓ 3. Interrogative Sentences 

These sentences are used to ask questions about the past.

📌 Structure:
Did + Subject + Verb (1st form) + Object?

✨ Examples:

• Did you play cricket?
• Did she go to school?
• Did they watch a movie?

💡 Explanation:
👉 The sentence starts with Did, and the verb stays in the 1st form.

⭐ Important Rules to Remember

• Affirmative → Use 2nd form of verb
• Negative → Use did not + 1st form
• Question → Use Did + 1st form
• “Did” already shows past, so we do not use the 2nd form after it
