High-Brow and Erudite, and, Dare We Say It, Sesquipedalian
If you had to look up "erudite" or "sesquipedalian" in the dictionary after we used those words to characterize The Black Prince, thumbing through those pages or clicking through those search results will have given you some good practice for the task to come.
Just take a look at this beaut of a passage and you'll see what we mean:
And yet, so complex are minds and so deeply intermingled are their faculties that one kind of change often images or prefigures another of, as it seems, a quite different sort. One perceives a subterranean current, one feels the grip of destiny, striking coincidences occur and the world is full of signs: such things are not necessarily senseless or symptoms of incipient paranoia. They can indeed be the shadows of a real and not yet apprehended metamorphosis. Coming events do cast shadows. (1.17.3)
When it comes to Bradley Pearson's writing style, The Black Prince takes a lesson from Shakespeare's Hamlet and lays the words, words, words on thick.
