A complete guide to who, which, that, whose, whom & where
Used when the antecedent is a person (or sometimes a pet) and acts as the subject of the relative clause.
The object form of who. Used when the antecedent is a person and acts as the object of the relative clause. More formal; often replaced by who in spoken English.
Used when the antecedent is a thing, idea, or animal. In non-defining clauses, only which is possible (not that).
Used in defining relative clauses for both people and things. Cannot be used in non-defining clauses (those with commas).
The possessive relative pronoun. Used for people, animals, and things to show belonging or relationship.
Used when the antecedent is a place. Equivalent to "in/at/on which" — but far more natural in everyday usage.

| Defining | Identifies which person or thing. Essential information — removing the clause changes the meaning. | No commas | Yes |
| Non-defining | Adds extra information about an already-identified noun. The clause can be removed without changing the core meaning. | Commas required | No — use who / which |
