Crossword: Word Game — Acknowledgements

The puzzles in this app were built offline with the help of the word lists below. The app does not include these data sets;
it includes only the finished puzzles. The clues are original.

English Speller Database (ESDB, previously SCOWL)
-------------------------------------------------

Permission to use, copy, modify, distribute, and sell any part of the English
Speller Database (ESDB, previously known as SCOWLv2), or word lists
created from it, is hereby granted without fee, provided that the above
copyright notice appears in all copies and that both the above copyright
notice and this notice appear in supporting documentation. Kevin Atkinson
makes no representations about the suitability of this database for any
purpose. It is provided "as is" without express or implied warranty.

ESDB is derived from many sources, most of which are in the Public Domain.
The primary source of words for ESDB comes from 12dicts and ENABLE2K, both in
the Public Domain; Alan Beale is the author of 12dicts and a major contributor
to ENABLE2K.

Some words used come from the UK Advanced Cryptics Dictionary:

There are no other restrictions: I would like to see the list
distributed as widely as possible.

WordNet was used to help with the initial part-of-speech assignment in ESDB:
