Nouns are more than just names—they are the heart of every sentence. They represent people, places, things, ideas, and emotions. But nouns don’t just exist in sentences—they act, they receive, they belong, and they explain. Let’s explore the functions of nouns, their types, rules, exceptions, and examples in a thorough and practical way.
I. Functions of Nouns in Sentences
1. Subject
A subject is the noun that performs the verb’s action.
Example: The teacher explained the lesson.
→ "Teacher" is the subject who does the explaining.
2. Direct Object
A direct object is the noun that receives the action.
Example: She reads a novel.
→ "Novel" is the direct object being read.
3. Indirect Object
An indirect object tells to whom or for whom the action is done.
Example: He wrote his mother a letter.
→ "Mother" is the indirect object receiving the letter.
4. Object of a Preposition
When a noun follows a preposition (like in, on, at, with), it is called the object of the preposition.
Example: The phone is on the table.
→ "Table" is the object of the preposition "on".
5. Appositive
An appositive is a noun that renames or explains another noun.
Example: My brother, a doctor, lives in Mumbai.
→ "A doctor" is the appositive, explaining "my brother".
6. Subject Complement (Predicate Noun)
A subject complement follows a linking verb and renames the subject.
Example: Mr. Sharma is a teacher.
→ "Teacher" renames Mr. Sharma and complements the subject.
