Confused between didn\t vs didnt? This is a very common mistake in English writing—especially in exams, emails, and online chats.
Let’s make it simple and crystal clear.
✅ The Correct Form
✔ Didn’t — Correct
❌ Didnt — Incorrect
📖 Why “Didn’t” Is Correct
Didn’t is a contraction of:
Did not → Didn’t
The apostrophe (’) replaces the missing letter “o” from “not.”
❌ Why “Didnt” Is Wrong
- It misses the apostrophe
- It is not grammatically correct
- It is not accepted in formal writing
🧠 Easy Memory Tricks
1. Always Expand It
If you can say:
did not
Then you must write:
didn’t
👉 Never: didnt ❌
2. Apostrophe = Missing Letter
- Didn’t = did + n + ’ + t
- The ’ replaces the “o”
3. Check Similar Words
All follow the same rule:
- don’t ✔ (do not)
- can’t ✔ (cannot)
- won’t ✔ (will not)
👉 So: didn’t ✔
✍️ Examples in Sentences
- I didn’t understand the question.
- She didn’t call me yesterday.
- They didn’t finish the work on time.
