As, when and while are conjunctions. In some uses as, when and while can mean the same, but they can also have slightly different meanings. We use them to introduce subordinate clauses.

We can use as, when and while to mean ‘during the time that’, to connect two events happening at the same time:

Another coach-load of people arrived as we were leaving.

We often use them with the past continuous to refer to background events:

When the men were out working in the field, I helped with milking the cows, feeding the calves and the pigs.

While he was working, he often listened to music.

We can put clauses with as, when and while before or after the main clause. When they come before the main clause, we use a comma:

As she was leaving the court, a crowd of photographers gathered around her. (before the main clause, followed by a comma)

Steven was very unhappy when things weren’t going well for him.

Lucy came into the room while he was waiting.
