@Sharon Foster Thanks for your thoughts. Unfortunately, it's not that simple. Asking KDP Support doesn't mean much because one support rep might think the word "relieve" is fine and another one might say that it's problematic. It all depends how the bots interpret the word. Also, things have gotten more strict with titles and subtitles over the years. Several years ago you could upload a title and subtitle that was drenched in keywords and it was fine. Now, KDP is much more strict about keyword stuffing. They also seem to be more strict about medical claims etc. In terms of adjusting the title...KDP is able to adjust your paperback subtitle slightly. For example, If you have the word "The" on your cover but you forgot to put it into your paperback title, they can add it for you. They can also add any commas or hyphens that were missed. In terms of the ebook title, we can do those kinds of adjustments ourselves. I'll ask KDP about revising the word, but who knows what they'll say. Other than that it's a choice between taking a risk and keeping it as is to save my reviews and Great on Kindle status, or unpublishing the book and republishing it with a new subtitle. That will mean losing the reviews and Great on Kindle status.
