Favorite is a noun in that sentence.
predicate
in can be both depending on the sentence its in. More frequently though it is a predicate.
In forming a sentence, you should have the subject and the predicate. The subject is what the sentence is all about. The predicate describes the subject. For example, My mother cooked my favorite crispy fried chicken. In this sentence, "my mother" is the subject and the predicate is "cooked my favorite crispy fried chicken" If it's only a simple subject and predicate, then, the simple subject is "mother" and the simple predicate is "cooked". I hope that can help :))
Is
depends
No: "favorite" in the sentence given is a noun, specifically a predicate noun, as indicated by its possessive pronoun/functional adjective modifier "your"
what is the predicate of this sentence also among my basballe treasures is a book about Clemente's life and career
There is no predicate. Why there is no predicate because the predicate is usually the verb then the rest of the sentence. so their is only an simple predicate which is move.
The predicate in the sentence is "is a book about Clemente's life and career." It includes the verb "is" and the noun phrase "a book about Clemente's life and career," which completes the predicate by describing what the subject possesses.
The predicate states what the subject does, is doing, or has done in a sentence.
The subject of the sentence is "Dad." All the rest of the sentence is the predicate.
