用法筆記

Frequently confused with 'began' (the simple past form). 'Began' stands alone as a past-tense verb; 'begun' must be paired with an auxiliary verb ('have', 'has', 'had', or 'be'). This is the only sense of 'begun' — it functions solely as a past participle and does not appear as a main verb on its own.

常見錯誤

❌I begun my homework yesterday.
✅I began my homework yesterday.
💡'began' is the simple past form and does not need an auxiliary verb.
❌She has began her new class this week.
✅She has begun her new class this week.
💡Use 'begun' (past participle), not 'began' (simple past), after 'has', 'have', or 'had'.
❌The project had began before the deadline.
✅The project had begun before the deadline.
💡After 'had' in the past perfect, always use the past participle.
