Pronouns substitute other nouns. Also, these are very effective cohesive device.
If a story is about a mother Simona, the story will sound repetitive if name ‘Simona’ is repeated again and again.
Examples:
The passage sounds very repetitive and it lacks coherence and flow. Also, it sounds like we are not talking about one person but more than one who have similar name. However, in the beginning of the passage, it is appropriate to use noun so reader knows whom writer is talking about.
If name is replaced with pronoun, it will make more sense, coherence and flow.
it will be like this:
The personal pronouns are She and her, I and me, you, he and him, it, we and us, they and them.
Examples:
Relative pronouns are used to connect relative clauses to independent clauses. Often, they introduce additional information about something mentioned in the sentence.
Relative pronouns include that, what, which, who, whose and whom. Traditionally, who refers to people; whereas which and that refer to animals or things.
Examples:
Whether you need commas with who, which, and that depends on whether the clause is restrictive or non-restrictive.
Who and whom are most confused pronouns. Who is a subject pronoun, like I, he, she, we, and they .Whom is an object pronoun, like me, him, her, us and them. When the pronoun is the object of a verb or preposition, the object form (whom) is used.
Whom is trickier, because it usually comes before the verb or prepositions that modifies it.
Examples:
Substitute who/whom with personal pronoun to see which one goes in a specific sentence.
Find the place where the personal pronoun would normally go and see whether the subject or object form makes more sense.
Examples:
Who/whom did you speak to earlier?
Replace who/whom with he/him earlier?
Observe if object pronoun (him) goes well in the sentence then use (whom)
Examples:
There is always a confusion to use pronoun I. Remember I is a subject and me is an object pronoun. See the difference in the following examples.
Examples:
The correct pronoun is me instead of I. It can be checked if you remove other name.
That, this, these and those are demonstrative pronouns. They take the place of a noun or noun phrase that has already been mentioned.
This is used for singular items that are nearby.
These is used for multiple items that are nearby. The distance can be physical or metaphorical.
Examples:
That is used for singular items that are far away.
Those is used for multiple items that are far away. Again, the distance can be physical or metaphorical.
Examples:
Indefinite pronouns are used for a person or thing that is not specifically identified. Some common indefinite pronouns are one, other, none, some, anybody, everybody, and no one.
Examples:
Reflexive pronouns end in -self or -selves: myself, yourself, himself, herself, itself, ourselves, yourselves, themselves.
Reflexive pronoun is used when both the subject and object of a verb refer to the same person or thing. These are also used to emphasize.
Examples:
Possessive pronouns come in two categories: limiting and absolute.
Limiting pronouns are: My, your, its, his, her, our, their and whose. They are used to show that something belongs to an antecedent.
Examples:
The absolute possessive pronouns are mine, yours, his, hers, theirs, and ours.
The absolute forms substitute for the thing that belongs to the antecedent.
Examples:
Some possessive pronouns are easy to mix up with similar-looking contractions.
Examples:
Keep in mind, possessive personal pronouns do not include apostrophes.
Interrogative pronouns are used in questions. The interrogative pronouns are who, what, whom, whoever, which, and whose.
Examples:
An antecedent is a noun or noun phrase that you mention at the beginning of a sentence or story and later replace with a pronoun. Pronoun it refers to anything, feelings, and places. Therefore, antecedent helps the reader to know for whom the pronoun is used.
Examples:
Antecedent (Simona and Zaki) makes it clear for the reader that pronoun he is used for Zaki (boy) and she is used for Simona (girl)
