Introduction
The purpose of this document is to provide a historical record of words deleted from the Scrabble list at various stages in its life. One not infrequently hears players saying things like ‘I’m sure word x used to be good – when did that get deleted?’ or conversely, ‘I thought we had deleted word x – when did that come back?’ This document will answer such questions.
The body of the document details the words that were deleted at each of thelist updates, from 2003 on. Rationales are given for each deletion. This is followed by Appendix 1, which repeats all this information but in the form ofa single alphabetically ordered list, making it easy to look up the history of any particular deleted word.
Note that by ‘Scrabble list’ is meant the British version, now known as Collins or CSW. The Americans have a different list, currently known as OTACWL, that has its own history, and which I am not concerned with here, except to observe that as a general policy over the years words have not been deleted from the British list if they were also to be found in the American list; conversely we do normally follow suit in deleting ‘American only’ words if the Americans delete them from their list. The idea here has been to preserve the American list as far as possible as a pure subset of the British one. Sadly this ‘pure subset policy’ has broken down a little in recentyears in that TWL has seen fit to include a handful of erroneous forms that we have found unacceptable and so have declined to add, but the principle remains that we do not delete our own words if they are in the American list, it’s just that we now sometimes fail to add their words.
General Principles of Deletion
The principle followed up to and including CSW12 was that words were deleted from the list if they were no longer supported by any of our current sources. From CSW15 this principle was changed, and from then on words were only to be deleted if they proved to have been included in error e.g.
were now admitted by the lexicographers to have been dictionary misprints (it does happen), or had been a mistaken inflectionary inference on the part of the DC which new evidence overturned.
The reason for this change was primarily that in CSW15 a considerable number of words which had been deleted in CSW12 because they were no longer supported by the latest edition of Chambers now reappeared in the latest edition of Collins, so had to be added again. This was getting a bit silly, and very confusing for Scrabble players who hate deletions anyway. There is also the consideration that finding words no longer in the dictionary (as distinct from finding new words added to the dictionary, which is relatively easy given a thorough knowledge of the existing list) involved a quite disproportionate amount of effort, since the only way to do it is to go through ticking off all the words that are still to be found in the sources and then seeing what you are left with not ticked.
Deletions prior to OSWI (1988-2003)
The first official Scrabble list, known as OSW (Official Scrabble Words) was published in 1988, and was based solely on the then current edition of Chambers dictionary, which had replaced the Shorter Oxford as the approved source in 1980. I assume that some deletions may well have takenplace when new editions of this list were published in the years between 1988 and 2003, but I have no record of these and none appears to be available, except in the case of two-letter words, where Allan Simmons has compiled a document setting out the history of these dating back to 1980. I include this as an Appendix 2.
Deletions in OSWI (2003)
In 2003 the American sources were for the first time united with the British source (Chambers) to produce what was then called OSWI (Official ScrabbleWords International) or SOWPODS (a term created as an easily pronounced anagram of OSW and OSPD). I have been unable to find any records relating to the word list before OSWI so I do not know whether any words that had been in OSW were deleted at this time. There is no mention of any deletions in the OSWI Initiation Kit produced at that time by Allan Simmons,so my assumption is that there were none.
Deletions in CSW07 (2007)
This was the first list in which the Collins dictionary was added as a source on the British side, to sit alongside Chambers. There was no new input fromChambers for this update. There was a small number of genuine deletions according to the rules then in force, but in addition a number of deletions were made for political rather than lexicographical reasons, in that various perfectly valid words that were (and still are) to be found in the Chambers dictionary were omitted at the request of Collins in order to provide a ‘differentiator’. My view is that this was in principle an unfortunate concession to commercial pressures, though in practice the words removed
for this reason were for the most part obscure 9-letter words most unlikely to be played. I have assumed that any inflections they had were removed too, though this is not actually spelled out in the CSW07 Initiation Kit. In a few cases these differentiator words were subsequently reinstated, either because they were now included in Collins anyway or because I came acrossthem while mining Chambers, thought they were new and didn’t realise they weren’t supposed to be there. So, the following words were removed:

Deletions in CSW12 (2012)
The CSW12 update reflected new words added to Collins English Dictionarysince the 2007 update and also, for the last time, new words added to the Chambers English Dictionary since the 1998 edition: after this Chambers was no longer used as a source, though existing ‘Chambers only’ words were retained. There was no input from the American list for this update. The table below gives a complete list of the 396 words deleted in CSW12 and attempts to explain the rationale in each case.
General points worth noting are:
the great majority of deletions were due to words that had been present in CH98 (the 1998 edition of Chambers) no longer being present in CH11 (the 2011 version of Chambers), or now being capitalised, or now being hyphenated, or now being labelled as abbreviations. Remember that Chambers Dictionary was not used to provide input to CSW07, so more than a decade's worth of changes onthe Chambers front had to be taken into account. Although the quantity of words being deleted was, as a result, larger than usual andsome of these words may have become well-established in the Scrabble lexicon, it was felt by the DC at the time that to retain wordsno longer supported by the source dictionaries simply out of sentiment or because of their utility would be inconsistent with past updates and was not an option. (This view was later abandoned, see the CSW15 section)
It will be noted that various interjections lost their plurals. It had always been the case that plurals of interjections were allowed only if they were specified in the dictionary, and there had been no change tothe DC policy in this respect; what had changed is the Chambers policy, such that plurals were no longer shown for interjections endingin –O
a small number of words were removed by the DC as part of a review of phrasal words. This is a tricky area in which it is difficult to achievea level of consistency that satisfies everybody, but the decision was made by the national associations to leave this matter to the discretion of the DC, and that discretion was duly exercised
no words were removed, even if not supported, capitalised or hyphenated, if they were also still to be found on the US list
quite a few of these deleted words were then restored in CSW15, for reasons explained in that section

Deletions in CSW15 (2015)
This update drew on new words added to the Collins English Dictionary since the CSW12 update plus a substantial number of new words from what was then the latest incarnation of the American list (TWL14). Chambers wasno long used as a source.
As far as deletions go, for CSW15 a new policy was introduced, under whichwords would no longer be deleted from the list simply because they were nolonger supported by the source dictionaries, but would be deleted only if it was established that their inclusion had been a mistake in the first place e.g. a misprint in the dictionary. There were no such cases in CSW15, so no new deletions were made.
Note also that the edition of the Collins dictionary used for this update was a good deal more comprehensive than any that had gone before, with many obscure or archaic words now being included that were previously only to be found in Chambers, with some supplementation from the OED. This resulted in the reintroduction of a number of words that had been deleted inCSW12 because at that time they were no longer to be found in Chambers, as noted above, but were now to be found in Collins.
Deletions in CSW19 (2-15 letters) (2019)
This update drew on new words added to the Collins English Dictionary since the CSW15 update plus a number of new words from what currently remains the latest incarnation of the American list (TWL18).
As stated above, the policy of the Dictionary Committee from CSW15 on hasbeen to delete words only if they are found to have been wrongly included in the list, due, for example, to misprints in the source dictionaries or an incorrectly inferred plural or verbal inflection, and not, as with updates up to and including CSW12, simply because they have been dropped from the source dictionaries. For CSW19 this applied to the following 29 words:

APPENDIX 2: A History of Two-letter Words
The following table is the work of Allan Simmons, and shows the evolution of the Scrabble word list (British version) in respect of the two-letter words that have been allowed at various stages in its history dating back to 1980. Note:
Bracketed words in red are those in the dictionary but disallowed by rules at the time (e.g. names of letters, foreign, obsolete)
Postal Scrabble Club allowed everything in Chambers dictionary including capitalised entries, which is why AB and RA were allowed atthe time
The column for 2019 has been added by me. I do not know if the new additions EW, OK and ZE were ever allowed at an earlier time, prior to OSWI. In the case of EW and ZE it seems unlikely.
