And then next week we will get an article on how not to alienate your readers with pointless, highfalutin language like "sagacious" and "jubilant."

It's a huge blind spot for writers to believe that repetition has a cost, but large vocabularies don't. This is ingrained in them by English teachers, because avoiding repetition and using lots of fancy words is hard work, and thus that is what teachers value.

For most readers, though, the opposite is closer to the truth: They will ignore repetition (or might even interpret it as useful structure) until the point where it becomes ridiculous, but they quickly get stuck on odd words or language usage that requires them to work to read a piece.
