Common Mistakes with the Verb ‘begin’
The verb begin is one of the most frequently used irregular verbs in business English, yet it causes confusion because of its three distinct forms: begin (present), began (past), and begun (past participle). The most common mistake is using begun alone as a simple past tense, or using began where a helping verb is needed. This guide explains exactly how to use each form correctly in emails, meetings, and everyday writing.
Quick Answer: The Three Forms of ‘begin’
| Form | When to use | Example |
|---|---|---|
| begin | Present tense (now, habits, future) | We begin the meeting at 10 AM. |
| began | Simple past (finished action) | The project began last Monday. |
| begun | Past participle (with have, has, had) | She has begun the report. |
If you remember only one rule: never write “I begun” or “she begun” without a helping verb like have, has, or had.
Why Learners Confuse ‘began’ and ‘begun’
The problem is that many irregular verbs follow a pattern where the past and past participle are the same (like send – sent – sent). But begin changes completely: begin → began → begun. Your ear might tell you that begun sounds like a past tense, but it is not. It always needs a helper.
Formal vs. Informal Tone
In formal business writing, you will see begin used more often than start. Begin sounds slightly more professional and deliberate. In informal emails or conversation, start is common, but you still need to use the correct form of begin when you choose it.
Comparison Table: ‘begin’ vs. ‘start’ (common confusion)
| Situation | ‘begin’ (correct) | ‘start’ (also correct) |
|---|---|---|
| Formal meeting | Let us begin the presentation. | Let us start the presentation. |
| Email to a client | We will begin the review next week. | We will start the review next week. |
| Conversation | I began the training yesterday. | I started the training yesterday. |
Both are correct, but begin is often preferred in written instructions and formal announcements.
Natural Examples in Business Contexts

Common Mistakes with ‘begin’
Mistake 1: Using ‘begun’ as simple past
Wrong: “The project begun last week.”
Right: “The project began last week.”
Why: Begun is the past participle and cannot stand alone as a past tense verb.
Mistake 2: Forgetting the helping verb with ‘begun’
Wrong: “She begun the analysis.”
Right: “She has begun the analysis.” or “She began the analysis.”
Why: Without has, have, or had, the sentence is grammatically incomplete.
Mistake 3: Using ‘began’ with a helping verb
Wrong: “We have began the negotiations.”
Right: “We have begun the negotiations.”
Why: After have, has, or had, you must use the past participle (begun), not the simple past (began).
Mistake 4: Confusing ‘begin’ with ‘start’ in formal writing
While both are correct, using begin in formal documents (like contracts or official announcements) is more appropriate. Start can sound too casual in those contexts.
Better Alternatives and When to Use Them
Sometimes you may want to avoid repeating begin too often. Here are alternatives with different nuances:
- Commence – Very formal. Use in legal documents or official ceremonies. “The training will commence on June 1.”
- Launch – Use for products, campaigns, or initiatives. “We launched the new software last quarter.”
- Initiate – Use for processes or procedures. “The manager initiated the review process.”
- Start – Neutral and common. Use in most everyday situations.
Choose begin when you want a professional but not overly formal tone. It is a safe choice for most business emails and conversations.
