Let's break it down:
* Determiner Phrase: It describes or modifies a noun (usually the subject of the sentence) and comes before it. In this case, it's describing whatever the subject is (we don't know from the given phrase).
* Predicate Adjective: It describes the subject of the sentence and follows a linking verb (often "to be" or forms of "to be").
The full sentence would need to include a subject and a linking verb to understand the context fully. For example:
* "The book is not yours." Here, "not yours" modifies the subject "book" and follows the linking verb "is".
* "This car is not yours." Here, "not yours" modifies the subject "car" and follows the linking verb "is".
