* Verbs: Show action or a state of being. They are the heart of a sentence, telling us what's happening.
* Nouns: Are the people, places, things, or ideas that the verb is acting upon.
Even seemingly simple sentences like "Wow!" or "Help!" have implied nouns and verbs:
* Wow! (Implied verb: "I am" and noun: "surprised")
* Help! (Implied verb: "Please" and noun: "me")
So, to answer your question directly, there is no sentence that can exist without a verb and a noun.
