Yellowstone is a noun (n) in the given sentence "Others, including Yellowstone, the first national park, are located far from big cities."
<h3>What is a concrete noun?</h3>
Concrete nouns designate physical things that, at least in theory, can exist. Although many philosophical and scientific schools may disagree with this supposition, most people accept that something exists and be perceived by at least one sense, such as sight, sound, smell, or touch (for instance, chair, apple, Janet, or atom). On the other hand, abstract nouns relate to abstract objects, i.e., ideas or concepts (such as justice or hatred). Some nouns have more than one sense, including both concrete and abstract ones, despite the fact that this distinction is occasionally exclusive. Take the noun art, which typically refers to a concept (e.g., Art is an important component of human culture) but which, in some contexts, can also refer to a specific piece of art.
