“Which” and “Where” are common relative pronouns in English, especially in IELTS grammar structures. Many learners often confuse them due to their similar usage in relative clauses. This article will help you understand the key differences and apply them accurately in your writing.
1. Definition and Structure of “Which”
Which is a pronoun that means “which one,” “what,” or “which things.” It is commonly used in questions or to replace a noun that refers to a thing in a relative clause.
Structures of “Which” in Questions:
Structure | Example |
|---|---|
Which + noun + is/are + S | Which artist is your favorite? |
Which + noun + do/does + S + V | Which sport do you like best? |
Which + do/does + S + V | Which do you like more, the pink or white one? |
Which + is/are + S | Which is your preferred choice? |
Structures of “Which” in Relative Clauses:
Structure | Example |
|---|---|
… noun (thing) + which + verb | The PC which keeps breaking down is under guarantee. |
… noun (thing) + which + subject + verb | The shoes which she lost cost her a fortune. |
Note: If “which” acts as an object, it can be omitted. Example: The bicycle (which) her father bought is very useful.
2. Definition and Structure of “Where”
Where means “at which place” or refers to a location. It can be used in questions or as a relative pronoun replacing a noun that indicates place in a relative clause.
Structures of “Where” in Questions:
Structure | Example |
|---|---|
Where + do/does + S + V | Where do you live? |
Where + is/are + S | Where are your cats? |
Structure of “Where” in Relative Clauses:
Structure | Example |
|---|---|
… noun (place) + where + S + V | The place where I used to walk is now restricted. |
Ha returned to her hometown where she was born and raised. |
3. How to Distinguish Between “Which” and “Where” in Relative Clauses
Criteria | Which | Where |
|---|---|---|
Meaning | Which one, what | Where, at what place |
Replaces | Nouns referring to things or events | Nouns referring to places |
Followed by | A subject or verb | A full clause |
Note: If both “which” and “where” refer to place, use:
Where if followed by a full clause: This is the restaurant where we met.
Which after a preposition for a more formal tone: This is the library at which we met.
