The document discusses defining and non-defining relative clauses. Defining relative clauses provide essential information to the meaning of the sentence, while non-defining clauses provide non-essential information. It also covers the relative pronouns that, which, who, when, and where and notes that the relative pronoun can be omitted when it is the object of the relative clause.

1. RELATIVE
CLAUSES

2. RELATIVE SENTENCES
 Defining relative clauses:
They are used to give essential information. Without
this information, the sentence would not make sense.
Example: They've sold the grocery where I used to go
shopping
RELATIVE PRONOUNS
That/ which To talk about things. That is
more informal than which
or who
Who/ that To talk about people
When To talk about times/periods
Where To talk about places

3. RELATIVE CLAUSES
 Non- defining relative clauses:
They are used to give non-essential information.
Without this information, the sentence would still
make sense.
Example: My sister, who I live with, knows a lot about
cars.
RELATIVE PRONOUNS
which We can’t use that in this
type of clauses
Who To talk about people
When To talk about times/periods
Where To talk about places

4. RELATIVE CLAUSES
 Omission of the relative pronoun:
 Examples:
She loves the chocolate (which / that) I bought.
We went to the village (which / that) Lucy
recommended.
We can omit the relative pronoun when it is the object,
not the subject, of the relative sentence.
