*Noun in Apposition or Appositve Noun*
A Noun in Apposition or Appositive Noun is a noun or noun phrase that identifes or clarifies another noun or noun phrase.
It provides additional information or restatement of the preceding noun called an Antecedent.
A Noun in Apposition is placed next to another Noun or Noun Phrase to further describe or identify it.
Example:-
My sister, Neha, is a
singer.
Here Neha is a Noun in Apposition to the Noun Phrase 'My sister'.
Appositives are often set off by a comma (,) but it is not always necessary.
If the appositive is essential to the meaning of the sentence, it is not followed by a comma. It is called Restrictive Appositive Noun.
If the Noun is Apposition isn't essential to the sentence's core meaning it is called a Non-restrictive Apposition and it is always followed by a comma.
Preety, my sister, danced in the programme.
Here the appositve noun 'my sister', is an Non- restrictive Noun in Apposition and is therefore, followed by a comma.
Now let's see the following sentence-
The capital of Switzerland Jurikh is a popular destination for the travellers coming from different parts of the world .
It is a Non -restrictive Noun in Apposition.
A Non-restrictive Appositive Noun adds bonus information which may be interesting and useful, but the sentence would still make sense and express the same point without it. The antecedent is already identifiable without the appositive. We all know the name of the capital of Switzerland .
Let's we see another
sentence
My car, a white Tata Altroz, was hired by the club members.
Here the maker or the colour are not needed to identify the car as you know it is my car and I have not more than one car. If I had had more than one car, I would have said " one of my cars'' or "my new car" etc.
On the other hand a Restrictive Noun in Apposition which is not followed by a comma provides information which is very essential to the meaning of the core sentence. A restrictive appositive adds information which is necessary to identify it's antecedent. If we remove the appositive the sentence would be unclear .
Jeherul my friend is a good story-teller.
Here the appositive 'my friend' is a restrictive Noun in Apposition and it is considered to be the essential to the core meaning of the sentence. There may be more than one man in a locality whose name is Jehirul. But I am saying about a particilar Jehirul, the one who is my friend.
