Classical Usage: This might be HBS’s ignominy. She uses it a lot. I first encountered it in Chapter 4 when she discusses the cooking skills of Aunt Chloe. Unfortunately, she’s a might proud of her work, and “she would narrate the fruitless efforts that one and another of her compeers had made to attain to her elevation.”
Classically Mad Usage: I think this is probably one of those words, like chirurgical, that I will steer away from since I assume most people would think that I just got midword confused.
