Here's why:
* Abstract nouns represent concepts, ideas, qualities, or states of being. They cannot be touched or seen.
* Corporation refers to a legal entity, a concept created by humans.
* You can't physically touch or see a corporation itself; it's a legal construct.
Example:
* "The corporation announced its new product line." (The focus is on the concept of the corporation, not a physical entity.)
