Here's why:
* Concrete noun: A match can refer to a physical object used to start a fire. This is a tangible, physical thing.
* Abstract noun: A match can also refer to a state of similarity or compatibility. For example, "There is a match between the fingerprints and the suspect." In this case, "match" represents an idea or concept rather than a physical object.
So, the answer depends on the specific usage of the word "match".
