What you might be thinking of are intensifiers, which are words that emphasize or strengthen the meaning of another word.
Here are some examples of intensifiers that can be used with pronouns:
* Adverbs: very, really, extremely, absolutely, totally, completely
* Adjectives: great, huge, tremendous, incredible, fantastic
* Pronouns: myself, yourself, himself, herself, itself, ourselves, yourselves, themselves
Examples:
* "I am very happy to see you." (adverb)
* "This is an absolutely amazing opportunity." (adverb)
* "She is a great friend." (adjective)
* "They are totally exhausted." (adverb)
* "I did it myself." (pronoun)
It's important to note that not all intensifiers can be used with all pronouns. For example, you wouldn't say "I am very myself," because "myself" is already an intensifier.
