I think that some basic conceptual analysis can be important for clarifying discussion given that many of these words are used and will continue to be used. For example, it is useful to know that “justified true belief” is a useful first approximation of what is meant by knowledge, but that the situation is actually slightly more complicated by that.
On the other hand, I don’t expect that this will work for all concepts. Some concepts are extremely slippery and will lack enough of a shared meaning that we can provide a single definition. In these cases, we can simply point out the key features that these cases tend to have in common.
