Jane Austen's influence on English language

A recent Guardian article on Jane Austen as the "queen of modern slang:" fits quite well with a piece I wrote a few months back about the influence of her work on the literature that followed -- as confirmed by big data in The Big Wow-Wow & a Bit of Ivory

The Guardian article informs us that
Oxford professor Charlotte Brewer told the Hay Festival in Hay-on-Wye that while Austen had a great influence on the first Oxford English Dictionary published in 1928, she is quoted 1,640 times in the most recent edition.Entries include 321 phrases from her 1815 novel Emma, which includes ‘dinner-party’ and  ‘brace yourself’. She also came up with ‘if I’ve told you once, I’ve told you 100 times’.
As the piece is very short, though, it adds in a piece of what it considers good news: an upcoming  BBC adaption of Death Comes to Pemberly. I don't usually like the modern writers' takes on the most popular couple of Pride and Prejudice. Someone picked out that book for me once, and I couldn't even bring myself to finish it. That's saying quite a bit. However, I have no objection to the Jane Austen stamps issued by the UK recently. They are little works of art in themselves.
