It would appear that lists of words violate the provision that Wikipedia should not have articles which define individual words, nor should it include Lists of such definitions. However, we have http://en.wikipedia.org/wiki/Category:Lists_of_words , http://en.wikipedia.org/wiki/Category:Lists_of_slang and http://en.wikipedia.org/wiki/Category:Lists_of_phrases , among others. Policy is descriptive, not prescriptive. Is this policy still being applied (in which case, *all* of these articles must be deleted), or not (in which case the wording of the policy needs to be changed). I have raised the issue at http://en.wikipedia.org/wiki/Wikipedia_talk:What_Wikipedia_is_not#Lists_of_W...
I don't know if all of these articles need to be deleted, or whether policy needs to be modified to reflect reality. But I think this needs to be determined in general, not determined piecemeal
