Relative pronouns and clauses

15 min

A relative clause gives more information about a noun. It begins with a relative pronoun.

Relative pronouns

  • who: for people (subject). The girl who won the race is my sister.
  • whom: for people (object). The man whom we met is a doctor.
  • whose: possession. The boy whose bag was stolen reported to the teacher.
  • which: for things and animals. The book which I borrowed is interesting.
  • that: for people or things in defining clauses. This is the house that Jack built.
  • where: for places. This is the school where I studied.

Defining vs non-defining clauses

  • Defining: necessary information, no commas. Pupils who study hard pass.
  • Non-defining: extra information, with commas. Nairobi, which is the capital of Kenya, is busy. (Do not use that here.)

Joining sentences

I met a teacher. She teaches chemistry. → I met a teacher who teaches chemistry.

Key points to remember

  • who/whom for people; which for things
  • whose shows possession
  • Non-defining clauses take commas and never "that"
  • where for places
