Past Participle of Begin: Meaning and Examples
The past participle of begin is begun. While begin is the base form (present tense) and began is the simple past tense, begun is the form you must use with auxiliary verbs like have, has, had, is, are, or was. For example: She has begun her new job. or The meeting had begun before I arrived. Understanding this distinction is essential for clear writing and speaking in English.
Quick Answer: Began vs. Begun
If you only remember one thing, remember this: begun never stands alone. It always needs a helper verb. Began is the simple past and can stand alone.
- Began = simple past (no helper verb). Example: The concert began at 8 PM.
- Begun = past participle (needs have, has, had, or a form of be). Example: The concert has begun.
