Here's why:
* Nouns are words that represent people, places, things, or ideas.
* Names are words that identify specific people, places, or things.
For example:
* John is a name, and it's a noun that represents a person.
* Paris is a name, and it's a noun that represents a place.
* iPhone is a name, and it's a noun that represents a thing.
However, sometimes names can function as other parts of speech depending on context. For example:
* "John is a good student." (John is a noun, the subject of the sentence.)
* "I met John yesterday." (John is a noun, the object of the verb "met".)
* "This is John's book." (John's is a possessive noun, modifying the noun "book".)
