Here's why:
* Intensive Pronouns: These are pronouns like "myself," "yourself," "himself," "herself," "itself," "ourselves," "yourselves," and "themselves." They add emphasis to a noun or pronoun already in the sentence. For example, "I did it myself."
* Singular Pronouns: These pronouns refer to one person or thing. Examples include "I," "you," "he," "she," "it," and "one."
While some intensive pronouns are singular (e.g., "myself," "himself"), the term "singular intensive pronoun" isn't commonly used in grammar. Instead, we talk about intensive pronouns that are used in the singular.
Key Point: It's important to use the correct pronoun based on the subject of the sentence and the intended emphasis.
