Is There a Difference Between Plistomy and Plisestomy?

I think that using stuff like etymology, plistomy, lexicography, all this stuff can be really sort of interrelated. So for an example, after fog, I thought, what does fog do? It impairs visibility when you're on the road, for example. Perhaps an extension from fog would be blindness. Deafness relates to blindness because they're both privation of senses. They're both in the same domain of experience. And so it would be possible from blindness to develop into deafness. That's where you're free associating and developing out this word story.
