Choose perfect participles, passive participles, or reduced relative clauses to shorten related ideas while keeping their meaning and subject clear.
What is it for?
Learn to combine related ideas and remove unnecessary words without losing meaning.
What you need to know
- Use having + past participle for an action completed before another action.
- Use a past participle to give background information about a person or situation.
- Remove a relative pronoun and a form of be when the meaning stays clear.
- Use an absolute construction when a separate situation explains the main action.
- Check that every opening participle clause has the correct subject.
1. Show which action happened first
Use having + past participle for an earlier, completed action.
The main clause usually describes the next action.
This form helps readers see the order without reading several separate sentences.
- Pattern: Having + past participle, subject + main verb.
- Put a comma after the opening clause.
- Use this form when the earlier action matters to the next one.
- Do not use having + past participle for an action that happens later.
2. Give background with a past participle
A past participle can describe a person or situation affected by something.
This form often replaces a longer clause with a passive meaning.
It works well when the cause or situation explains the main action.
- Pattern: Past participle + extra information, subject + main verb.
- Common openings include faced with, given, and informed of.
- Use given when a fact or condition affects a decision.
- Make sure the main subject matches the person or thing described.
3. Shorten relative clauses
A reduced relative clause gives information about a noun in fewer words.
For an active meaning, use a present participle.
For a passive meaning, use a past participle.
Keep the noun close to its description so readers understand the sentence.
- Active: people who are waiting becomes people waiting.
- Passive: forms that were completed becomes forms completed.
- Remove who, which, or that with a form of be when possible.
- Do not remove words if the result changes the meaning.
4. Use absolute constructions carefully
An absolute construction adds background information to a whole sentence.
It has its own subject and does not share the main clause's subject.
Use it when the situation helps explain the result.
- Pattern: Noun + participle, main clause.
- The deadline being near, we worked through lunch.
- The meeting having ended, everyone returned to work.
- Use a comma to separate the opening construction from the main clause.
5. Avoid dangling participles
An opening participle clause must describe the correct subject.
A dangling participle seems to describe the wrong person or thing.
Check the first noun after the comma.
If that noun cannot perform the opening action, rewrite the sentence.
- Incorrect: Having checked the figures, the report was sent.
- Correct: Having checked the figures, Maya sent the report.
- The report cannot check figures. Maya can.
- Sometimes, repeating the subject makes the sentence clearer.
6. Choose the right form before joining sentences
First, identify the relationship between the actions.
Use having + past participle for an earlier completed action.
Use a passive participle when something receives an action.
Use a reduced relative clause when extra information describes a noun.
Keep separate sentences when compression makes the meaning unclear.
- Before: Nina checked the stock. She ordered more supplies.
- After: Having checked the stock, Nina ordered more supplies.
- Before: The chairs were damaged. The chairs were replaced.
- After: The damaged chairs were replaced.
- Before: The workers were waiting outside. They entered at nine.
- After: The workers waiting outside entered at nine.
How to do it, step by step
- Identify the main action and the extra information.
- Decide whether the extra information shows time, cause, or description.
- Choose the correct participle or reduced clause.
- Place the clause beside the subject or noun it describes.
- Check the verb form, comma, and meaning.
