You could try contacting HP and asking if the quotes containing old English words are what are actually causing the problem. Someone may manually read through it and allow it through the QA because the words are being used properly in the quotes. I don't know if that will help, but it's worth a try.
Just took this interesting quiz and came out with an estimated vocabulary of 32,700 English words - a bit lower than I would have liked. Time to crack the books, I guess. What's your score?http://www.testyourvocab.com/
