A relative pronoun is a pronoun that introduces an adjective clause.
In English, the relative pronouns are that. which, where, who, whom, whose.
- Who and whom refer to people.
- Which refers to things.
- That and whose refer to people or things.
A relative pronoun is used to start an adjectival clause which describes a noun (also called a relative clause.).
The description comes after the noun to either identify it or give more information about it…
Identifying the noun
- The man who invented zips became very rich.
- I recognised the car which was involved in the accident.
- We did not see the dog that attacked our rabbit.
Be aware that a fair proportion of your readers will not like you using that for people. It is good advice to avoid using that for people, especially in formal writing.
Note : colloquially, that is often used to represent a person or people and who is used to represent an animal or animals; though neither is technically correct they seem to be commonly accepted… one for the Grammar Nazis, eh?
