1. Starting a Sentence With ‘When’
Subordinating conjunctions, such as «when«, always join an independent clause and a dependent clause.
When the weather is gloomy, some people feel miserable.
As a general rule, if the when-clause (dependent clause) comes first, we need a comma after it.
When the sky is clear and blue, we go to the beach.
When the sky is clear and blue we go to the beach.
Instead of introducing a clause, we can use «when» to introduce a phrase. Phrases, unlike clauses, do not have a subject and a verb. In this situation, if the introductory phrase is brief (less than five words) and the sentence is clear, the comma is optional.(1)
When in town we go to a fancy restaurant.
2. Starting a sentence with the Independent Clause
Look at this sentence:
I enjoy visiting Buddhist temples when I travel to Japan.
The first clause («I enjoy visiting Buddhist temples») is the independent or main clause; it expresses a complete thought and can stand alone.
If the when-clause follows the main clause, the comma before «when» is generally unnecessary.
You exchange incoming oxygen with outgoing carbon dioxide when you take a deep breath.
3. Parenthetic Expressions Starting With ‘When’
We can also use «when» to introduce a parenthetic phrase or clause; that is, a part of a sentence that does not define or limit. Parenthetic expressions just provide additional information, which can be safely omitted without changing the meaning of the sentence.
In 1879, when Albert Einstein was born, Russia and the United Kingdom signed the Treaty of Gandamak.
Note that the clause «when Albert Einstein was born» is parenthetic; it can be easily omitted without changing the meaning of the sentence. Parenthetic clauses should be placed between commas.
In 1962, when Marilyn Monroe died, the Soviet Union began to install nuclear missiles in Cuba.
In 1962 when Marilyn Monroe died the Soviet Union began to install nuclear missiles in Cuba.
4. More Examples
- I experience heartburn when eating spicy food.
- When going out with my friends, I enjoy eating pizza.
- Call me when you are ready.
- When you are hungry, you can eat healthy food (e.g., salads, fruits, or smoothies).
- You never know when you may need to call her.
- When stock prices go up, interest rates go down.
- Will Rebecca stop me when I kiss her?
- There were many people when I arrived at the party.
- When you buy a property in Spain, you will have to pay some taxes.
5. Conclusion
Follow these simple guidelines to decide whether to use commas in a «when» sentence:
- If a sentence starts with a when-clause, include a comma after the first clause.
- If the when-clause comes at the end of the sentence, a comma is often unnecessary.

What’s the difference between the subordinate conjunctions when and while?
When & While: The Short Answer
In some sentences, you can use either without a great change in meaning. Generally, if you want to focus on an action that has a duration being in progress, use a while + a progressive tense.
While I was washing the dishes, my wife came home.* (Washing the dishes has a duration, e.g. 4 minutes.)
(*Note you can also use when here, but as a general rule, while is suitable.)
In other cases when you don’t need to emphasize that an action was in progress or the action is short and without a significant duration, use when and a simple tense.
When it started to rain, we went inside. (The action started is short; it is not something in progress).
When it started to rain, we went inside.
Here are some tips on the use of these two conjunctions.
Tip #1: Use a Progressive (Continuous) Tense with While to Show Focus
Progressive tenses use the BE verb + a verb in ~ing form.
While I was cooking dinner, the phone rang.
I will be sleeping at 11:00 p.m. tonight, so don’t phone me.
We use while to focus on an action happening at a specific time. Therefore, the most natural verb tense to use is a progressive tense, which shows that an action is in progress at a certain time.
It is common to use while with actions happening at a specific time (e.g. at 11 p.m.). Also, we use while to show that a shorter action (usually in the past simple, e.g. the phone rang) happened during as a longer action (usually in past progressive, e.g. I was cooking dinner). Often this shorter action interrupts the longer action.
A sensible rule is to use while with the progressive tenses and when with the simple tenses.
Tip #2: Use While with Actions that have a Limited Duration
- When I was a child, I played soccer. (Correct)
- While I was a child, I played soccer. (Not natural)
Why is #2 not natural? Well, when an action is too long (e.g. I was a child), we lose focus. The period of twelve years when you were a child is too long to use a progressive tense. We don’t use ‘while’ to talk about long periods of our lives. Instead, we use when and past simple. There’s another reason.
Tip #3: Use While with Action Verbs
Also, «While I was a child» is unnatural because the BE verb (was a child) is a state verb. State verbs are not action verbs (e.g. jump, kick, shower, drink). Instead, state verbs describe states or conditions (e.g. BE, live, understand, know, exist). We do not use progressive tenses with state verbs. As a result, we generally don’t use while with state verbs.
Compare:
While she was driving, I played with the radio. (Natural)
This is correct. Driving is an action verb and the action is limited in duration. In other words, driving is a short activity that has a clear start and end.
While When I lived in my hometown, my mother made me dinner. (While is not natural)
Live is a state verb, and also, the action of living in my hometown probably had a duration of 18 years. This is too long to focus on.
Exception: Focusing on a Verb in Progress
You could use while with a state verb like ‘live’ if you really want to focus on the fact that an action was in progress at a specific time. For example:
While I was living in India, there was a big earthquake.
Although it would probably be more common to use When I lived in India, this sentence is correct. The speaker chooses to use ‘While’ + present progressive’ to focus on an action being in progress (living) when another action happened.
Remember: While Means an Action Had a Start and an End (a Duration)
If a sentence uses while, it suggests that the action happened over a period of time. Here’s are two better examples to show what I mean:
When the phone rang, I was making lunch.
The longer action (making lunch) was happening when a shorter action happened (phone rang).
Key question: How many times did the phone ring? Because we’re using when, we don’t know. The use of when doesn’t suggest it was an ongoing action. The phone may have rang once and stopped.
While the phone was ringing, I was making lunch.
How many times did the phone ring here? More than once. Because we are using While + present progressive, we are focusing on duration. This means that the action (ring) happened over a period of time that had a start and end. When we say ‘the phone was ringing’ in the progressive, we are saying that this happened for some time. (Thanks to Clive at Englishforums for this point.)
While vs. When: In Conclusion
We can conclude the following:
- To emphasize (focus) that an action was in progress at a specific time, use while + a progressive tense ( = While I was eating, …)
- Otherwise, use when + a simple tense. (= When I ate, …)
- Verbs with while have a duration. The period of the verb cannot be too long or we lose focus. (= While I was a child = When I was a child)
- Progressive tenses use action verbs, so use while with an action verb (While I was dancing) and not a state verb (While I was hungry)
I hope these ideas have been useful. Remember, these are general tips (not fixed rules). There will be exceptions depending on what the speaker wants to emphasize. If you have any questions or comments, please leave them below.
