What is a appositive type of pronoun that renames noun?

There's no such thing as an "appositive type of pronoun." An appositive is a noun or noun phrase that renames another noun or noun phrase. It's usually placed right next to the noun it renames, set off by commas.

Pronouns, on the other hand, are words that replace nouns. They don't rename them.

Here's an example of an appositive:

* My brother, a talented artist, won first place in the competition.

In this sentence, "a talented artist" is the appositive because it renames the noun "brother."

Here's an example of a pronoun replacing a noun:

* He won first place in the competition.

The pronoun "he" replaces the noun "brother" in the previous sentence.

In summary, appositives rename, while pronouns replace. They are different grammatical structures and don't overlap.
