It seems that
annals was originally excluded from Chi, as a plural, but I changed this in 2008, to allow both
annal and
annals as rare words. There's not much background info about this change. In 2007 I actually conducted a survey in the forum to see if the plurals policy should be changed. In the process of reporting that most of those who'd voted had opted to leave the policy as it was,
I remarked:
I'll continue to refine the word list from time to time, to include words wrongly excluded under the rule. (A couple of examples I'm aware of are "besides" and "annals".) There seem to be quite a few such cases, so if you spot one, let us know.
In fact, I never got around to changing
besides, which remains to this day excluded, but I did change
annals. Unfortunately the annals of Chi are not comprehensive enough to throw any more light on these events.
At any rate, I have no doubt that
annalist is not a common word, so I'll change it.
