* Gerund Phrase: "washing dog" (a noun phrase acting as a noun)
* Direct Object: Receives the action of the verb.
* Predicative Nominative: Renames or identifies the subject.
To determine the function of "washing dog," we need a complete sentence.
Here are some examples:
* "My favorite activity is washing dogs."
* "Washing dogs" is the predicative nominative because it renames the subject "activity."
* "He enjoys washing dogs."
* "Washing dogs" is the direct object because it receives the action of the verb "enjoys."
Without a sentence, we can't definitively say whether "washing dog" is a direct object or a predicative nominative.
