Simple Background: Where Do These Words Come From?

The base verb is begin.

It has three main forms:

• begin (base form / present)
• began (past simple)
• begun (past participle)

Many English verbs change like this. For example:

• go → went → gone
• see → saw → seen
• begin → began → begun

So, began and begun are just different forms of the same verb. They are not different meanings. They are different uses.

Clear Explanation of the Difference

Let’s explain this in the easiest way possible.

What “Began” Means and How to Use It

Began talks about something that started in the past.

You use began:

• When the action is finished or clearly in the past
• When there is no helper verb

Examples:

• The movie began at 7 p.m.
• She began her job last week.
• The rain began suddenly.

Think of began as a simple past action. It tells when something started.

What “Begun” Means and How to Use It

Begun is never used alone.

You must use begun with:

• has
• have
• had

Examples:

• The movie has begun.
• They have begun the project.
• The class had begun before I arrived.

Begun often focuses on:

• The result
• The connection to now
• The fact that the action is already started

Common Mistakes People Make

Many learners make the same mistakes again and again. Let’s fix them.

Mistake 1: Using “has began”

• ❌ The meeting has began.
• ✅ The meeting has begun.

Why? Because has needs the past participle.

Mistake 2: Using “begun” without a helper

• ❌ The meeting begun at noon.
• ✅ The meeting began at noon.

Why? Because begun cannot stand alone.

Mistake 3: Mixing time words

• ❌ It has begun yesterday.
• ✅ It began yesterday.

Words like yesterday, last night, and last year usually go with began, not has begun.
