What Does Each Word Mean?
Both began and begun come from the verb begin, which means to start something.
However, they’re used in different tenses.
1. Began – Past Tense of Begin
“Began” is the simple past tense form of “begin.”
You use it when talking about something that started in the past and is already finished.
✅ Examples:
- I began my homework after dinner.
- She began to cry when she heard the news.
- They began their journey early in the morning.
Think of “began” as a word that stands alone. It does not need “have,” “has,” or “had.”
2. Begun – Past Participle of Begin
“Begun” is the past participle form of “begin.”
It’s always used with helping verbs like has, have, or had.
✅ Examples:
- I have begun my project.
- The rain had begun before we reached home.
- She has begun practicing for the competition.
So remember: “begun” can’t stand alone — it needs a helper verb!
The Key Difference Between Begun and Began
Here’s a simple comparison to make it crystal clear:
| Feature | Began | Begun |
|---|---|---|
| Tense | Simple Past | Past Participle |
| Helper Verb? | ❌ No | ✅ Yes (has/have/had) |
| When to Use | Something started and finished in the past | Something started in the past and continues or connects to now |
| Example | She began painting yesterday. | She has begun painting a new picture. |
🧠 Quick Tip to Remember:
If you see has, have, or had, use begun.
If there’s no helper verb, use began.
Common Mistakes and How to Avoid Them
Even advanced learners mix these two up! Let’s fix that once and for all.
🚫 Incorrect:
- I have began a new diet.
✅ Correct: - I have begun a new diet.
👉 Why? Because “have” needs a past participle — that’s begun, not began.
🚫 Incorrect:
- The movie has began already.
✅ Correct: - The movie has begun already.
👉 “Has” always pairs with begun.
🚫 Incorrect:
- We had began the test before the teacher came.
✅ Correct: - We had begun the test before the teacher came.
When to Use Began
Use began when describing something that started and ended in the past.
It works perfectly in stories, reports, or past experiences.
✅ Examples:
- The rain began at noon.
- I began to feel sleepy during the lecture.
- They began talking about their future plans.
- The teacher began the lesson with a smile.
- We began our trip last Sunday.
📝 Memory Trick:
Think of began = yesterday.
If it happened yesterday, “began” is the right choice!
When to Use Begun
Use begun when the action started earlier but connects to now — or when it’s part of a perfect tense.
✅ Examples:
- I have begun reading a new book.
- She had begun to cry before he apologized.
- The festival has begun already.
- We have begun to understand each other better.
- It had begun snowing before we arrived.
🧩 Memory Hack:
“Begun” loves helpers — if you see has, have, or had, it’s begun time!
