What are the 7 functions of noun in a sentence?

There isn't a fixed list of exactly 7 functions of nouns in a sentence. Instead, nouns have several functions depending on their role within the sentence. Here are the most common ones:

1. Subject: The noun performing the action of the verb.

* The dog barked at the mailman.

2. Direct Object: The noun that receives the action of the verb.

* The mailman delivered the package.

3. Indirect Object: The noun that receives the direct object.

* He gave his friend a gift.

4. Object of a Preposition: The noun that follows a preposition.

* She sat on the chair.

5. Appositive: A noun that renames another noun.

* My friend, John, is coming over.

6. Predicate Nominative: A noun that follows a linking verb and renames the subject.

* My neighbor is a doctor.

7. Noun of Direct Address: A noun used to directly address someone.

* John, please pass the salt.

Remember, these are just the most common functions. Nouns can also have other roles in more complex sentence structures.
