Time clauses with when and while

Connect past actions by showing whether they happened together or one interrupted another.

Time clauses with when and while show how past actions relate. For two actions in progress at the same time, the lesson uses Past Continuous in both clauses, with while introducing one of them. For an interruption, the longer action is in the Past Continuous and the shorter action is in the Past Simple. Only when introduces the shorter action; either when or while can introduce the longer action. A when- or while-clause may come first or in the middle. Put a comma after it only when it comes first.

✎Parallel actions
  1. 1Meaning: Two actions were in progress at the same time.
  2. 2Forms: Use Past Continuous for both actions.
  3. 3Sentence: 'While Aysel was reading, Murad was writing.' The opening time clause takes a comma.
✎An interrupted action
  1. 1Longer action: 'The students were talking' was already in progress.
  2. 2Shorter action: 'The bell rang' interrupted it.
  3. 3Sentence: 'The students were talking when the bell rang.' When introduces the shorter Past Simple action.
💡Ask what happened first

If one action was already in progress, make it Past Continuous; make the shorter interruption Past Simple.

🚫Short action connector

When the time clause presents the shorter interrupting action, use when.

💡Comma check

Use a comma after an opening when- or while-clause. Do not insert that comma when the time clause comes second.
