Here's why:
* Status: Refers to a position or condition, which is an idea rather than a physical object. You can't touch or see someone's "status." It's a concept.
* Prospect: Represents a possibility or expectation, which is also an intangible idea. It's the idea of what might happen in the future, not a concrete thing.
In contrast, concrete nouns refer to physical objects or entities that can be perceived by the senses. For example, "table," "tree," or "dog" are concrete nouns.
