Such a generous offer, M, but I'm happy with the many other dictionaries I already have, of which the best is the amazing Compact Edition of the Oxford English Dictionary. In case you haven't seen one, it's 2 huge volumes with each page having 4 photoreduced pages of the full dictionary - so it comes with a magnifying glass! Entries include the history of the word, often with its first usage ... hence my use of the word amazing. It's great for lovers of words like us.
Thanks again for your kind words and kind offer.
