In
another topic there was some discussion of this, and the apparent inconsistency of
reist being allowed while
reism is not. To cut a longish story short,
reist was accepted in the Chihuahua lexicon because of other meanings, and as it happens Wiktionary (the source of the definitions displayed in Chi) is unaware of those meanings.
Reism does not seem to be in any general dictionary other than Wiktionary, not even in the massive OED. In recent times I've been more receptive to admitting extremely rare words.
Reism tests this new-found tolerance almost to breaking point. I doubt if any player would have tried the word because of their familiarity with the philosophical writings of Kotarbinski in the 1920s. I checked out a few online glossaries of philosophical terms and none of them included
reism. However it is discussed at some length in the online
Stanford Encyclopedia of Philosophy, so I presume it's a term familiar to at least some scholars in that discipline.
I will admit
reism as a rare word.
