Hello everyone!
This is the new topic you are working on these days, here you have a useful table that will help you to understand the difference and between defining and non-defining relative clauses.
Also, you can take a look to the second table below to revise the use of the relative pronouns:
| relative pronoun | use | example |
|---|---|---|
| who | subject or object pronoun for people | I told you about the woman who lives next door. |
| which | subject or object pronoun for animals and things | Do you see the cat which is lying on the roof? |
| which | referring to a whole sentence | He couldn’t read which surprised me. |
| whose | possession for people animals and things | Do you know the boy whose mother is a nurse? |
| whom | object pronoun for people, especially in non-defining relative clauses (in defining relative clauses we colloquially prefer who) | I was invited by the professor whom I met at the conference. |
| that | subject or object pronoun for people, animals and things in defining relative clauses (who or which are also possible) | I don’t like the table that stands in the kitchen. |
