I’m currently reading The Duke and I and the author is constantly using the word “acerbic”. I had never heard of the word before now and had to google the definition. The word has shown up so much that I’m tempted to go through the book and count its appearances lol.
Have you noticed any authors having favorite words that they use page after page?
Nora Roberts/JD Robb has many, many characters ‘draw in a breath’ while thinking before they speak. Many.
Lois Bujold, in her science fiction and fantasy, uses ‘suffused’ an average of once per book. Which isn’t much over all, but it’s about once per book more than most authors would use it.
