I would like to be able to use The New Oxford American Dictionary with the Unregistered, offline-only Kindle.

I have read the Dictionary FAQ and it doesn't address this topic. 'The New Oxford American Dictionary' appears in this menu with a check-mark next to it.

The dictionary is easy to access and makes it swift and painless to find the. I can tap that dictionary name ('The New Oxford American Dictionary') and a new menu aepars called 'Select New Dictionary'. One of the most useful Kindle Paperwhite features is the built-in dictionary. When I highlight a word and navigate to the dictionary pop-up window, the message displayed is 'No definition found.' The Kindle Oasis does, however, indicate that the New Oxford American Dictionary is present and detected in the 'Dictionaries' menu, and does appear as an option in the Dictionary pop-up box that appears when you highlight a word. I side-loaded a copy of the New Oxford American Dictionary from a Kindle Paperwhite (Firmware Version Kindle 5.12.2 (3569610025)) using Calibre 5.4.2 to a Kindle Oasis (Firmware Version Kindle 5.13.2 (3661420039).
