Over at io9 there’s this post, “How to make sure the language in your historical fantasy novel is period-accurate.” And while “fantasy novel” and “period-accurate” seem contradictory to me, I was happy that the article directed me to two interesting online resources that may also interest . . . you!
1. The Jane Austen Word List: Author Mary Robinette Kowal compiled a list “of all the words that are in the collected works of Jane Austen” (14,793!). You can install it as a “language” in OpenOffice (click here for instructions), then spell check your document against it, which will highlight any words that Austen didn’t use.
