Advanced Relative Clauses: Reduced, Nominal, and Prepositional

At C1 level, relative clauses can be reduced to participial phrases, used as subjects or objects (nominal), or formed with preposition + whom/which for a formal register.

Grammar Rule in 30 Seconds

Master complex sentence flow by omitting relative pronouns or shifting prepositions to the end of clauses for a more natural, academic tone.

  • Reduce relative clauses by removing the pronoun and 'be' verb: 'The man who is standing' becomes 'The man standing'.
  • Use nominal relative clauses (what/whatever/whoever) to act as a noun phrase: 'What he said was true'.
  • Shift prepositions to the end of the clause in informal contexts: 'The person to whom I spoke' vs 'The person I spoke to'.
Noun + (Relative Pronoun + be) + Participle/Adjective = Noun + Participle/Adjective

مرور کلی

## Defining vs Non-Defining (Quick Recap)
Defining: essential to identify the noun — no commas.
  • The email that arrived this morning is urgent.
Non-defining: adds extra info — use commas.
  • The email, which arrived this morning, is urgent.
## Reduced Relative Clauses
Drop the relative pronoun + auxiliary verb and use a participle instead:
Active (present participle -ing):
  • The student who is sitting by the door → The student sitting by the door
  • Anyone who wants to volunteer → Anyone wanting to volunteer
Passive (past participle -ed/-en):
  • The documents that were sent last week → The documents sent last week
  • The building which was designed in 1920 → The building designed in 1920
## Nominal Relative Clauses
No antecedent — the whole clause acts as a noun:
| Function | Example |
|---|---|
| Subject | What she proposed changed everything. |
| Object | I understand what you mean. |
| Complement | That is what concerns me. |
Other nominal relative words: whoever, whatever, however, wherever
  • Give it to whoever arrives first.
  • Whatever you decide, I will support you.
## Formal Prepositional Relatives
In formal writing, avoid ending with a preposition — move it before whom/which:
| Informal | Formal |
|---|---|
| the colleague I work with | the colleague with whom I work |
| the topic we argued about | the topic about which we argued |
| the reason he left for | the reason for which he left |
## Common C1 Mistakes
❌ The man which arrived... → ✅ The man who arrived...
❌ What that she said was true. → ✅ What she said was true.
❌ The issue about that... → ✅ The issue about which...
