So I'm reading a 19th-century novel called The Count of Monte Cristo, and I came across this particular usage, which is:
[H]e continued," let us make all possible speed. I are most anxious to finish my evening at the Duke of Bracciano's."
I'm aware some usages in the book tend to be rather old-fashioned, but I still find the use of "I are" very peculiar. Is this a common usage in older English or in literary works? Thanks.
