|The term SOWPODS was coined to cover the
convergence of the two International Scrabble©
word sources, OSW and OSPD, as deployed for the 1991
Championships in London and subsequent World Championships. SOWPODS
is an acronym derived from anagramming OSW and OSPD.
Tournament and Club Word List (OWL)
OWL is an expanded version of the Official Scrabble Players
Dictionary (OSPD) [3rd edition]. The additional words included in
OWL (but not OSPD) are mostly those which were expurgated (censored)
from OSPD for the popular market, i.e. words (arbitrarily)
considered offensive. OWL also goes up to 9 letters (plus
extensions), whereas OSPD only goes up to 8 letters (plus
extensions). OWL is "published" by the National Scrabble
Association (NSA) in the United States. It is distributed to NSA
members only. OWL is primarily used in North American and Israel.
OWL is also known as TWL98, which means Tournament Word List.
contains the words from the Official Word List 2nd edition, plus the Long
Word List. The OWL2 contains words up to nine letters long
plus their inflections, while the LWL contains words 10-15 letters long.
OWL14, work began
on OTCWL2014 soon after the
establishment of NASPA in 2009, with NASPA
Merriam-Webster negotiating the scope of
the changes involved, including the new word
references to be used. Then lexicographers
from both organizations started working in
parallel, with the MW team searching for
suitable words that had been added to the MW
database since the last edition, and the
Dictionary Committee (DC) looking for
new words in the Oxford College Dictionary,
2nd edition, and the Canadian Oxford
Dictionary, 2nd edition.
2014, the DC finished its work, which
also became the basis for the
Official SCRABBLE Players Dictionary's
5th edition, used in school and recreational
the third in the OTCWL series, and its
working title was OWL3. The name was changed
however, due to two concerns. One was that
with the inclusion of longer words of 10–15
letters, the nature of the book had
fundamentally changed; the other was that
the name of the first two volumes had been
prefaced by the name of our predecessor
NSA, and that our new book therefore
technically had a different name.
sees new words from three sources:
Merriam-Webster's database (essentially,
their 11th Collegiate Dictionary)
Oxford Dictionary, 2nd edition
College Dictionary, 2nd edition
for the first time words of up to 15
letters, which were formally only available
separately in the
almost 9,000 words that will be newly
acceptable in competitive play. The more
widely publicized figure of 5,000 new words
refers to those that are being added to the
OSPD5. 51% of the new words are
coincidentally found in the international
CSW2012 lexicon; the rest are not.
itself stands for Official Scrabble©
Words, a publication derived solely from the Chambers Dictionary,
published in Scotland. OSW is exclusively used in the United Kingdom
CSW07 List, Collins
Tournament and Club Word List. This is the authority for all
tournament and club play. All tournaments which are either run
and/or rated by the ABSP use this reference work as the arbiter
for determining the validity of every word played. It contains
every word added to TWL last year, and more new words obtained
from Collins English Dictionary.
CSW or Collins Scrabble Words
is the global world source used in Scrabble. CSW2018 is the
newest edition, in previous years the global word list was also
known as SOWPODS. CSW is not a single dictionary but an amalgam
of three: Collins (7th edition, 2005), Chambers (1998 edition)
and TWL, the current Northern American wordlist. TWL itself is
also drawn from a range of sources.
From August 2015 we will be
using CSW2012 and CSW2015, (Collins
Tournament and Club Word Lists).

Merriam-Webster's Dictionary, but also including words from four

is a major update of OSPD3, and contains many words found in
SOWPODS and OWL/TWL98.
We had hoped to
add OSPD5 once we could obtain the
official respective word lists when sanctioned by NAPSA on the
Internet, probably never as Hasbro will not allow that to happen
following countries are known to be fully SOWPODS:- Australia,
Bahrain, Ghana, Hong Kong, India, Japan, Kenya, Kuwait, Malaysia,
Malta, New Zealand, Nigeria, Oman, Pakistan, Philippines, Qatar,
Saudi Arabia, Singapore, South Africa, Trinidad, United Arab
Emirates, United Kingdom.
