What are Relative Clauses?

Relative clauses add extra information about a noun in a sentence. They are introduced by relative pronouns like 'who' (for people) and 'which' (for things). These clauses help make writing more descriptive and interesting.

Short answer

Relative clauses are dependent clauses that add information about a noun. Use 'who' for people and 'which' for things: 'The man who called was Tom' / 'The book which I read was great.'

Who vs Which in Relative Clauses
WHO (for people)
  • Refers to a person
  • The woman who works here
  • The children who play soccer
WHICH (for things)
  • Refers to things/animals
  • The car which broke down
  • The trees which are old
