Is appositive a simple tense of verbs?

No, an appositive is not a verb tense. It's a grammatical concept, specifically a noun or noun phrase that renames or clarifies another noun or noun phrase.

Here's the breakdown:

* Appositive: A word or phrase that renames or explains another noun. It is placed right next to the noun it modifies.

* Verb Tense: Indicates the time of an action or state of being (e.g., past, present, future).

Example:

* My dog, a golden retriever named Buddy, loves to play fetch. (The appositive "a golden retriever named Buddy" renames the noun "dog.")
