A relative clause describes “a noun” in the main clause. We use a relative clause beginning with “who” to describe “a person” or “people”.
Sometimes, instead of being the subject of a relative clause, who is the object of the finite verb in the clause we must add another object to the relative clause.
We use a relative clause beginning with “which” to describe “all nouns except people”.
A relative clause beginning with “that” can describe “all nouns including people”.
We use a relative clause beginning with “whose” to show that the noun after “whose” is related to or belongs to the noun before it.
A relative clause can be defining or non-defining.
A defining relative clause identifies all nouns we are referring to.
A non-defining relative clause does not identify all nouns we are referring to but only gives more information.
