Relative Clauses

RELATIVE CLAUSES: A SUMMARY

(Reference:   Collins Cobuild Student’s Gramar: 1991, Harper Collins, London)

• A relative clause is a type of subordinate clause embedded inside a noun phrase.
• It typically post-modifies the head noun of a noun phrase.
• It gives additional information to more narrowly define the head noun.
• It contains a verb which may be either finite or non-finite.
• A relative clause may or may not be introduced by a relative pronoun (that, which, who, etc)
  (see rules below)

1) Use ‘who’ or ‘that’ to introduce a relative clause when referring to people.

  Mele is the girl [who won the competition].
      She knew the man [that was killed in the accident].

      Use ‘that’ or ‘which’ to introduce a relative clause when referring to things.

      Here is the book [that was so famous].
      Give me the knife[ which is on the table].
