To determine whether "basketball" is a proper or common noun, we need to understand the difference between the two.

A proper noun is the specific name given to a particular person, place, or thing. It always starts with a capital letter. Examples of proper nouns include names of people (e.g., John, Emily), places (e.g., London, Paris), and specific organizations (e.g., Apple, Coca-Cola).

On the other hand, a common noun is a general name used to identify a class or category of people, places, or things. Common nouns do not require capitalization, unless they appear at the beginning of a sentence. Examples of common nouns include words like girl, city, and car.

In the case of "basketball," it is a common noun because it refers to a general sport or activity, rather than a specific person, place, or thing. So, the answer is: "basketball" is a common noun.
