Explain the concept of intensive pronouns and provide examples.

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" or "-selves" to certain personal pronouns. Intensive pronouns are not necessary for the sentence to make grammatical sense, but they add emphasis or stress to the subject or object of the sentence.

Here are some examples of intensive pronouns:

1. I myself will take care of the situation.
In this sentence, the intensive pronoun "myself" emphasizes the subject "I" and adds emphasis to the fact that the speaker will personally handle the situation.

2. She herself completed the entire project.
Here, the intensive pronoun "herself" emphasizes the subject "she" and highlights the fact that she completed the project without any external help.

3. The president himself addressed the nation.
In this sentence, the intensive pronoun "himself" emphasizes the object "president" and emphasizes that the president personally addressed the nation.

4. They themselves organized the event.
Here, the intensive pronoun "themselves" emphasizes the subject "they" and emphasizes that they took the responsibility of organizing the event.

5. You yourself can make a difference.
In this sentence, the intensive pronoun "yourself" emphasizes the subject "you" and emphasizes that the individual has the power to make a difference.

It is important to note that intensive pronouns are reflexive pronouns used for emphasis, but they differ from reflexive pronouns in that they are not essential to the sentence's meaning.
