Prepositions in Relative Clauses

Learn how to use prepositions in relative clauses to enhance clarity and formality in your writing.

Using Prepositions in Relative Clauses enhances sentence precision and formality. This lesson focuses on mastering this structure to improve your writing and speaking clarity.

Examples

Example 1

IncorrectThe house which I live in is old.

BetterThe house in which I live is old.

Placing the preposition before the relative pronoun is more formal.

Example 2

IncorrectThe company which she works for is expanding.

BetterThe company for which she works is expanding.

This structure is preferred in formal contexts.

How It Works

Meaning

Prepositions in relative clauses help specify relationships between the clause and the noun it modifies, often indicating time, place, or reason.

In relative clauses, prepositions can precede the relative pronoun or be placed at the end of the clause.

This structure is important at the B2 level for creating more complex and precise sentences.

Use it when

  • Describing the location or time related to the noun in the main clause.
  • Indicating a reason or method linked to the noun in the main clause.
  • Forming formal written or spoken responses where clarity is crucial.

See it

The book in which she is interested is on the table.
The city where I grew up has changed a lot.

Quick rules

  • Prepositions can precede the relative pronoun or follow the clause.
  • Use "in which," "on which," etc., for more formal writing.
  • Ensure the preposition fits the relationship between the clause and the noun.
  • "Where" and "when" can often replace "in which" or "at which."
