Participle clauses

Use present, past and perfect participle clauses to compress related information when the understood subject is clear and logically matches the main clause.

Overview

What this grammar does

Use present, past and perfect participle clauses to compress related information when the understood subject is clear and logically matches the main clause.

Form and rules

How it works

1

Present participle clauses (-ing) can express simultaneous action, reason or result: Knowing the risks, we delayed.

2

Past participle clauses can replace passive clauses: Built in 1890, the house needs repairs.

3

Perfect participle having + past participle makes earlier completion explicit: Having finished the report, she left.

4

The understood subject of the participle clause should normally be the same as the subject of the main clause to avoid dangling modifiers.

5

Reduced clauses are common in written/formal English but should not be used when the time or logical relationship becomes unclear.

Common mistakes

What to avoid

Perfect participle shows the report was completed before the emailing.

Building in 1885, the building is protected by law.
Built in 1885, the building is protected by law.

A past participle clause replaces a passive clause: Because/As it was built...
