The verb begin means to start something or cause something to start. It is one of the most common words in English and works in everyday conversation, professional writing, academic work, and formal documents.
However, not every alternative to begin works in every sentence. Words such as start, commence, launch, initiate, open, and embark on have related meanings but different levels of formality, context, and emphasis.
For example, you can begin a meeting, start a meeting, or commence a meeting, but these choices do not have exactly the same tone. Likewise, you can launch a product, but launch is more specific than begin because it suggests introducing something publicly.
This guide explains the most useful synonyms for begin, when they can replace it, and when another word is a better choice.

Common Mistakes
Mistake 1: Using Commence in Casual Conversation
Commence is grammatically correct, but it can sound unnecessarily formal.
Instead of:
Let’s commence dinner.
Natural:
Let’s start dinner.
Mistake 2: Using Launch for Everything
Launch usually suggests an official introduction or start.
Correct:
The company launched a new product.
Less natural:
I launched my homework.
Use:
I started my homework.
Mistake 3: Confusing Begin With Resume
Begin can mean start for the first time.
Resume means start again after stopping.
Correct:
The meeting began at 9.
The meeting resumed at 10 after the break.
Mistake 4: Using Initiate as a Universal Replacement
Initiate often suggests deliberate action or the activation of a process.
The manager initiated an investigation.
But:
The movie began at 8.
is much more natural than:
The movie initiated at 8.
Mistake 5: Forgetting the Preposition After Embark
The normal construction is:
embark on + noun
Correct:
They embarked on a new journey.
Not:
They embarked a new journey.
Mistake 6: Using Take Up With Every Activity
Take up often suggests adopting a new activity, hobby, or occupation.
She took up painting.
For a single session, use start:
She started painting at 3 p.m.
Mistake 7: Overcomplicating Simple Writing
Replacing every instance of begin with advanced vocabulary does not automatically improve writing.
Sometimes:
The meeting began at 9.
is better than:
The meeting commenced at 9.
Precision and naturalness matter more than complexity.
When Not to Replace Begin
Keep begin when it is already clear, natural, and appropriate.
For example:
The story begins with a mysterious phone call.
There is no strong reason to replace begins with commences.
Similarly:
The course begins next Monday.
is completely natural.
Use a different word only when it adds useful information:
The company launched its new product.
Here, launched tells the reader more than simply began.
Writing Tips
Avoid replacing begin merely to make your writing sound sophisticated.
A useful approach is to ask what kind of beginning you mean:
Start → ordinary beginning
Commence → formal beginning
Initiate → deliberate beginning of a process
Launch → official/public introduction
Open → beginning of a meeting or event
Embark on → beginning a significant journey or project
Resume → beginning again
Take up → beginning a new activity
Kick off → informal or energetic beginning
This approach creates more precise writing than simply searching for a more complicated synonym.
