The word lists included in this dictionary are in the public domain, per the following README file provided with the original en-CA.dic distributed by Kevin Atkinson. All updates to the wordlist are released to the public for the betterment of this word list.
The dictionary file was created using the "final" English and Canadian SCOWL
(Spell Checker Oriented Word Lists) wordlists available at Kevin's Word Lists
Page (http://wordlist.sourceforge.net). Lists with the suffixes 10, 20, 35,
50, 65 and 65 were used. Lists with the suffixes 70, 80 and 95 were excluded.
Copyright information for SCOWL and the wordlists used in creating it is
The affix file is identical to the MySpell English (United States) affix file.
It 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

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.

> I was wondering what the copyright status of your "UK English
> Wordlist With Frequency Classification" word list as it seems to
> be lacking any copyright notice.
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
Date: Tue, 11 Jul 2000 19:31:34 +0100
> 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.
The 12Dicts package and Supplement is in the Public Domain.

Inflections database, is under the following copyright:

The 50 level includes Brian's frequency class 1, words words appearing
in at least 5 of 12 of the dictionaries as indicated in the 12Dicts
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.
The name list from Alan Beale is also derived from the linux words
list, which is derived from the DEC list. He also added a bunch of
miscellaneous names to the list, which he released to the Public Domain.
The DEC Word list doesn't have a formal name. It is labeled as "FILE:
english.words; VERSION: DEC-SRC-92-04-05" and was put together by Jorge
Stolfi DEC Systems Research Center. The DEC Word
list has the following copyright statement:
To the best of my knowledge, all the files I used to build these
wordlists were available for public distribution and use, at least
for non-commercial purposes. I have confirmed this assumption with
the authors of the lists, whenever they were known.
Therefore, it is safe to assume that the wordlists in this package
can also be freely copied, distributed, modified, and used for
personal, educational, and research purposes. (Use of these files in
commercial products may require written permission from DEC and/or
the authors of the original lists.)
Whenever you distribute any of these wordlists, please distribute
also the accompanying README file. If you distribute a modified
copy of one of these wordlists, please include the original README
file with a note explaining your modifications. Your users will
surely appreciate that.
These files, like the original wordlists on which they are based,
are still very incomplete, uneven, and inconsitent, and probably
contain many errors. They are offered "as is" without any warranty
of correctness or fitness for any particular purpose. Neither I nor
my employer can be held responsible for any losses or damages that
may result from their use.
However since this Word List is used in the linux.words package which
the author claims is free of any copyright I assume it is OK to use
for most purposes. If you want to use this in a commercial project
and this concerns you the information from the DEC word list can
easily be removed without much sacrifice in quality as only the name
lists were used.
The file special-jargon.50 uses common.lst and word.lst from the
"Unofficial Jargon File Word Lists" which is derived from "The Jargon
File". All of which is in the Public Domain. This file also contain
a few extra UNIX terms which are found in the file "unix-terms" in the
The 60 level includes Brian's frequency class 0 and all words
appearing in at least 2 of the 12 dictionaries as indicated by the
12Dicts package. A large number of names are also included: The 4,946
female names and 3,897 male names from the MWords package and the
files "computer.names", "misc.names", and "org.names" from the DEC
The 65 level includes words found in the Ispell "medium" word list.

The 70 level includes the 74,550 common dictionary words and the 21,986 names
list from the MWords package. The common dictionary words, like those
from the 12Dicts package, have had all likely inflections added.
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,
and the 10,196 places list from the MWords package.
The ENABLE package, mainted by MCooper ,
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*

were not found anywhere else.
