Countless words have been spent on trying to formally define things like knowledge and truth. Has there ever been a successful attempt? If not, it seems like conceptual categories may be undefinable. I'm not saying we shouldn't attempt to create useful definitions for things, but why do we treat "justified true belief" as something that has to hold in all possible cases, when we know there is no definition that can do that? There will always be counterexamples, no matter how you define it.
