Can there be two nouns in a sentence?

Yes, absolutely! In fact, it's very common to have multiple nouns in a sentence. Here are a few examples:

* The dog chased the ball. (Two nouns: "dog" and "ball")

* My friend gave me a book about dinosaurs. (Three nouns: "friend," "book," and "dinosaurs")

* The company's profits increased this quarter. (Two nouns: "company" and "profits")

Nouns can have different roles in a sentence:

* Subject: The noun performing the action (e.g., "The dog" in the first example)

* Object: The noun receiving the action (e.g., "the ball" in the first example)

* Possessive: The noun showing ownership (e.g., "company's" in the third example)

* Appositive: A noun that renames or explains another noun (e.g., "my friend" in the second example)

So, you can definitely have more than one noun in a sentence, and they often work together to create a complete thought.
