THE IDEA, SIMPLY

The rule, with an example

A relative clause describes a noun. Who normally refers to people; which to things; whose to possession. A defining clause identifies which person or thing. A non-defining clause adds extra information and uses commas.

SEE IT IN CONTEXTThe student who organised the event thanked everyone. My tutor, who organised the event, thanked everyone.
Skills to work on in this practice
  • Connect details to the right noun
  • Choose a suitable relative pronoun
  • Decide whether information identifies or adds

Choose the pronoun by its role

UseExampleWhy it works
PersonThe tutor who helped me is here.Who is the subject of helped.
ThingThe book which I borrowed is useful.Which is the object of borrowed.
PossessionThe learner whose bag is blue is waiting.Whose connects the person with their possession.

Common mistake

Check: The tutor who she helped me

Use: The tutor who helped me

Who already supplies the subject; do not add she for the same role.

How should I practise this?

Read the example and explain the choice before answering. After the exercise, write a new sentence using the same pattern. Revisit any answer you could not explain, even if you guessed correctly.
