Are the sentence where were you are pronoun predicate nominative?

You're close, but not quite there! Let's break down the sentence "Where were you?"

* Subject: The subject is "you." This is the person or thing being talked about.

* Verb: The verb is "were." It tells us about the action or state of being.

* "Where" is an adverb: It modifies the verb "were," telling us *where* the subject was.

There's no predicate nominative in this sentence. A predicate nominative is a noun or pronoun that renames the subject. Since "where" tells us a location, it's not a noun or pronoun and therefore can't be a predicate nominative.
