A short participle clause can give background, a reason or an earlier action. Its form shows the relationship between events without adding another complete finite clause.

The idea

In these common clauses, the implied subject matches the main subject. Use -ing for an active meaning, a past participle for a passive meaning, and having + past participle for an earlier completed action. Having been warned is passive.

Examples

  • Walking along the canal, I spotted a kingfisher.
  • Damaged by the storm, the roof needed repairs.
  • Having checked the figures twice, Mina sent the report.
  • Not knowing the code, I waited by the gate.
  • While repairing the chair, Omar found a coin.
  • Having been warned about the ice, we took the path by the wall.

Watch out

A participle's name does not fix the event's tense. Avoid a dangling subject: Walking along the canal, the rain started wrongly attaches the walking to the rain. Write As I was walking along the canal, it started raining.
