Question

my dogs goal is to please. subject predicate nominative adjective

Explanation:

To determine the correct label for "to please" in the sentence "My dog's goal is to please", we analyze the sentence structure. The subject is "My dog's goal", the linking verb is "is", and "to please" follows the linking verb, functioning as a predicate nominative (a noun or noun - like phrase that renames the subject after a linking verb). "Subject" would refer to the noun phrase doing the action (or being described), and "adjective" would describe a noun, but "to please" is not an adjective. So "to please" is a predicate nominative.

Answer:

predicate nominative
