Explanation:
To utilize a noun, you must first define what it is you're referring to in the sentence. Alternatively, in general, a noun is a word that serves as the name for a particular thing or combination of things, such as a living being or a location.
Proper nouns, like Jane Smith or the Louvre Museum, can only be used to describe a single entity. Alternatively, a proper noun is a noun that refers to a specific person or object, does not need a limiting modifier, and is frequently capitalized in English.
A term that doesn't fit into any of those categories is neither.
