Relative clause? Defining relative and non defining relative clause

• What is a relative clause?

A relative clause gives more information about someone
or something referred to in a main clause. These clauses use the
following relative pronouns who, whose, what, where, when,
which, that ........

e.g. I managed to get all the books that you asked for.
Do you know the date when Joshi is going to get married?
Swetha, whose work of art has won the state uwurd is my
student.

I’ll enjoy eating whatever you cook.

There are two kinds of relative clauses, defining and nondefining.

A defining relative clause is used to specify which type of
person or thing we mean and this information helps to identify the person
or thing.

e.g. The teacher who teaches Mathematics lives next to us.
Abraham Stopped the Car that was driving fast.

A non-defining relative clause adds extra information about a
noun and this is information is not necessary to identify the person or
thing.

e.g. Vimala, who works in the computerr centre, is my friend.
In written form non-defining relative clause is distinguished from
the defining one with commas. Even while saying the sentence aloud
we need lo pause at the commas.

Note: Read the following two sentences and find how the
sentence without a pause gives a funny meaning:

My wife, who lives in Bangalore, arrives here tomorrow.(non-defining)
My wife who lives in Bangalore arrives here tomorrow.(defining)
