What are intensive pronouns and how are they used?

Intensive pronouns, also known as emphatic pronouns, are pronouns that are used to emphasize or intensify a noun or pronoun in a sentence. They are formed by adding "-self" (singular) or "-selves" (plural) to certain personal pronouns.

Intensive pronouns are used to draw attention to a specific noun or pronoun in a sentence, emphasizing its importance or significance. They are typically placed immediately after the noun or pronoun they are intensifying.

For example:
- She herself completed the project. (The intensive pronoun "herself" emphasizes the subject "she" and highlights that she personally completed the project.)
- I myself will take care of it. (The intensive pronoun "myself" emphasizes the subject "I" and emphasizes that the speaker will personally handle the task.)

It is important to note that intensive pronouns are not necessary for the grammatical structure of a sentence, and their absence does not change the meaning of the sentence. They simply add emphasis or intensity to the noun or pronoun they are referring to.
