Relative clauses: where/whose (intro)
Place and possession in defining clauses.
A defining relative clause tells us exactly which person, place, or thing we mean. You have already met 'who' (for people) and 'which'/'that' (for things). Now we add two more relative words. Use 'where' when the relative clause gives information about a place — the word 'where' replaces expressions like 'in it', 'at it', or 'on it'. Use 'whose' when the relative clause shows that the noun before it owns something — 'whose' replaces a possessive like 'his', 'her', 'its', or 'their'. The key test: if you can replace the missing word with 'in/at/on + a pronoun', choose 'where'; if you can replace it with a possessive pronoun, choose 'whose'. Remember that defining relative clauses have no commas because the clause is essential to the meaning of the sentence. For example: 'This is the village where my grandmother was born' uses 'where' because the clause identifies the place; 'She is the teacher whose lessons I enjoy most' uses 'whose' because the clause shows possession (her lessons).
Key terms
| Word | Refers to | Example |
|---|---|---|
| where | a place (city, town, room, school) | This is the town where I grew up. |
| whose | possession (people or things that own something) | She is the girl whose bag was stolen. |
| Word | Meaning | Example |
|---|---|---|
| where | in/at/on which (a place) | Baku is the city where I was born. |
| which | a thing (often needs a preposition for place) | The museum which we visited is being renovated. |
| whose | possessive determiner (his/her/its/their) before a noun | He is the student whose project won first prize. |
| who | the person who does the action (subject pronoun) | Do you know the boy who won the prize? |
- 1Sentence 1: The factory closed last year.
- 2Sentence 2: My father used to work at the factory.
- 3Find the shared noun: Both sentences mention the place 'the factory'. In Sentence 2 it appears as 'at the factory' (at + place), so we can replace 'at the factory' with the relative adverb 'where'.
- 4Combine: The factory where my father used to work closed last year. ('Where' replaces 'at the factory', so no preposition is needed and there are no commas.)
- 1Sentence 1: I spoke to a student.
- 2Sentence 2: Her essay was chosen as the best in the school.
- 3Find the possessive: Sentence 2 begins with the possessive 'Her', which points back to the student. A possessive (his/her/its/their) before a noun signals that we need 'whose'.
- 4Combine: I spoke to a student whose essay was chosen as the best in the school. ('Whose' replaces 'her' and comes directly before the noun 'essay'.)
Do not use 'which' for a place clause when no preposition is given. 'The museum which we visited' is fine because the museum is the object of 'visited', but for a location use 'where': 'the café where we had lunch' (not 'which we had lunch').
'Whose' shows possession; it is NOT the same as 'who's'. 'Who's' means 'who is' and can never come before a noun. Write 'the girl whose bag was stolen', never 'who's bag'.
'Whose' must be followed immediately by a noun (whose + noun): 'whose project', 'whose son', 'whose tactics'. Forms like 'the school whose I studied' or 'whose my sister works' are wrong because no possessed noun follows.
After 'where' or 'whose', do not keep the old pronoun. Say 'the town whose old bridge was built…' (not 'where its old bridge'), and 'the village where there is no supermarket' without repeating 'in it'.
Rules
- 1Use 'where' in a defining relative clause to refer back to a place noun (city, room, school, etc.).
- 2Use 'whose' in a defining relative clause to show that the head noun possesses something; 'whose' directly precedes the noun it modifies (whose + noun).
- 3Do NOT use 'where' for people or things; do NOT use 'whose' for places or abstract nouns unless true possession is involved.
- 4Defining relative clauses introduced by 'where' or 'whose' require NO commas — the clause is essential to identify which one.
- 5Quick test: replace the blank with 'in/at/on + pronoun' → choose 'where'; replace with a possessive pronoun (his/her/its/their) → choose 'whose'.
