Have you ever wondered whether to use “begun” or “began” when talking about something that started in the past? These two words come from the same verb, “begin,” but they are not interchangeable.
Choosing the wrong one can make an otherwise correct sentence sound grammatically awkward. The key difference is that “began” is the simple past tense, while “begun” is the past participle and usually needs a helping verb such as “has,” “have,” or “had.”
For example, you can say, “The movie began at 8 p.m.,” but “The movie has begun.” Understanding this simple distinction can make your English writing and speaking much more accurate.
Quick Answer
The difference between begun and began is simple:
- Began is the simple past tense of begin.
- Begun is the past participle of begin and is always used with a helping verb like has, have, or had.
Examples:

✅ She has begun her speech.
Easy Rule:
