The valid two-letter words always cause arguments. According to the makers of
the Scrabble game, there are a 109 2-letter words that are acceptable in the
British English version of their game. Interestingly, though there are only 96
in the North American version, it is not a sub-set: there are 12 extra words
not in the British English version (AB AG AL DE ED ET HM MM OP PE UH YA).

Although enthusiasts insist on the validity of all of these words, not many
people who play for fun enjoy using them in their games. The 'Adult' lexicon
supplied with !X-Word is meant for fun/friendly play so not all of the 109
British English words are there. The decision to leave out a word was largely
arbitrary -- it's not like I'm going to please everyone! The 'Adult109' lexicon
does contain all 109.

I have 3 half-megabyte lexcions: ChampOSPD2 and ChampTWL98 which both contain
the standard North-American set of 96, and ChampENABL which contains all 121
(combining the English and North-American words).

Here is the full list of 109 words. I have marked words that are not in the 'Adult'
lexicon with an asterisk (*). The only significance of the lowercase words is that
they are deemed 'commonplace'. Frankly I find a lot of them pretty dubious.
