How do I make the word event a pronoun?

You can't make the word "event" a pronoun. Pronouns are words that replace nouns, and "event" is a noun.

For example, you could use a pronoun like "it" or "that" to replace "event" in a sentence:

* Original sentence: The event was a huge success.

* Using a pronoun: It was a huge success.

* Using a pronoun: That was a huge success.
