Source Code License
The words of this dictionary and their correction rules are made available under a BSD-like licence, per the SCOWL Readme:
README file for en_US and en_CA Hunspell dictionaries
These dictionaries are created using the speller/make-hunspell-dict
script in SCOWL, version 7.1 released on January 6, 2011.
The NOSUGGEST flag was added to certain taboo words. While I made an
honest attempt to flag the strongest taboo words with the NOSUGGEST
flag, I MAKE NO GUARANTEE THAT I FLAGGED EVERY POSSIBLE TABOO WORD.
The list was originally derived from Németh László, however I removed
some words which, while being considered taboo by some dictionaries,
are not really considered swear words in today's society.
You can find SCOWL and friend at http://wordlist.sourceforge.net/.
Bug reports should go to the Issue Tracker found on the previously
mentioned web site. General discussion should go to the
wordlist-devel at sourceforge net mailing list.
COPYRIGHT, SOURCES, and CREDITS:
The en_US and en_CA dictionaries come directly from SCOWL (up to level
60) and is thus under the same copyright of SCOWL. The affix file is
a heavily modified version of the original english.aff file which was
released as part of Geoff Kuenning's Ispell and as such is covered by
his BSD license. Part of SCOWL is also based on Ispell thus the
Ispell copyright is included with the SCOWL copyright.

Alan Beale also deserves special credit as he has,
in addition to providing the 12Dicts package and being a major
contributor to the ENABLE word list, given me an incredible amount of
feedback and created a number of special lists (those found in the
Supplement) in order to help improve the overall quality of SCOWL.
The 10 level includes the 1000 most common English words (according to
the Moby (TM) Words II [MWords] package), a subset of the 1000 most
common words on the Internet (again, according to Moby Words II), and
frequently class 16 from Brian Kelk's "UK English Wordlist
with Frequency Classification".
The MWords package was explicitly placed in the public domain:
The Moby lexicon project is complete and has
been place into the public domain. Use, sell,
rework, excerpt and use in any way on any platform.
Placing this material on internal or public servers is
also encouraged. The compiler is not aware of any
export restrictions so freely distribute world-wide.

There were many many sources in total, but any text marked
"copyright" was avoided. Locally-written documentation was one
source. An earlier version of the list resided in a filespace called
PUBLIC on the University mainframe, because it was considered public

> So are you saying your word list is also in the public domain?
That is the intention.
The 20 level includes frequency classes 7-15 from Brian's word list.
The 35 level includes frequency classes 2-6 and words appearing in at
least 11 of 12 dictionaries as indicated in the 12Dicts package. All
words from the 12Dicts package have had likely inflections added via
my inflection database.

package, and uppercase words in at least 4 of the previous 12
dictionaries. A decent number of proper names is also included: The
top 1000 male, female, and Last names from the 1990 Census report; a
list of names sent to me by Alan Beale; and a few names that I added
myself. Finally a small list of abbreviations not commonly found in
other word lists is included.
The name files form the Census report is a government document which I
don't think can be copyrighted.

a few extra UNIX terms which are found in the file "unix-terms" in the

dictionaries as indicated by the 12Dicts package.
The 70 level includes Brian's frequency class 0 and the 74,550 common

like those from the 12Dicts package, have had all likely inflections
added. The 70 level also included the 5desk list from version 4.0 of
the 12Dics package which is the public domain.
The 80 level includes the ENABLE word list, all the lists in the
ENABLE supplement package (except for ABLE), the "UK Advanced Cryptics
Dictionary" (UKACD), the list of signature words in from YAWL package,

The ENABLE package, mainted by M\Cooper ,
is in the Public Domain:
The ENABLE master word list, WORD.LST, is herewith formally released
into the Public Domain. Anyone is free to use it or distribute it in
any manner they see fit. No fee or registration is required for its
use nor are "contributions" solicited (if you feel you absolutely
must contribute something for your own peace of mind, the authors of
the ENABLE list ask that you make a donation on their behalf to your
favorite charity). This word list is our gift to the Scrabble
community, as an alternate to "official" word lists. Game designers
may feel free to incorporate the WORD.LST into their games. Please
mention the source and credit us as originators of the list. Note
that if you, as a game designer, use the WORD.LST in your product,
you may still copyright and protect your product, but you may *not*
legally copyright or in any way restrict redistribution of the
WORD.LST portion of your product. This *may* under law restrict your
rights to restrict your users' rights, but that is only fair.
