Here's why:
* Abstract Nouns: Represent concepts, ideas, qualities, or feelings that cannot be physically touched or seen.
* Common Nouns: Refer to general, everyday things or people.
"Value" represents a concept or idea. It's not something you can hold in your hand. It's a quality, a worth, or a significance attributed to something.
For example:
* The value of education is immense. (Value refers to the worth or importance of education)
* He placed a high value on honesty. (Value refers to the importance he gives to honesty)
While we might talk about the "value of a car" or the "value of a house," these are instances where the abstract concept of "value" is applied to a concrete object.
