Answer :
Vietnam is the noun (n) in the sentence "One of the most popular national monuments is the Vietnam Veterans Memorial."
Define noun.
There have been instances where nouns have been defined in terms of the grammatical categories to which they belong (classed by gender, inflected for case and number). Due to the fact that not all languages have the same categories for nouns, such meanings frequently depend on the language. Nouns are commonly defined in terms of their semantic qualities, especially in informal contexts (their meanings). Words that refer to a person, place, thing, event, substance, quality, number, etc. are referred to as nouns. However, modern linguists have critiqued this kind of definition as being uninformative.
