In The Witch (2015), the script is written with Shakespearean construction (lots of thou's, and thee's and hast's), the actors were told to speak in a heavy Yorkshire accent, and a lot of the vocabulary is archaic (as well as some chunks were apparently 1:1 accurate as to what would be said at the time).
It takes place in early colonial 17th Century, circa 1630s.
What language would they speak in reality? How accurate is The Witch?
