An annoying thing about picking words to use for things is that major uses that came before are often inconsistent. For example, the word "atemporality" means interesting but slightly different things in the ways mean it, versus the way Ursula Le Guin used it

Philip K. Dick sense of it (though I'm not sure he ever actually used the word) is somewhere in between. A sort of hallucinatory time zone between actual and derealized experiences.

The earliest interesting sense of it that I can find, though without use of the term, is Lewis Carroll's handling of time experience (which Harold Bloom described as "only reality principle in wonderland is that time has been murdered")

At the risk of annoying all parties, I'm going to try an include-and-transcend operation and use atemporality as the label for an "all of the above" condition: murdered time, liminal time, cyclicality in domestic time experience, chaos in public time experience.

Isn't that the problem of defining something by what it isn't? I'm reminded of Catch 22 and the Anabaptist

Yes, same problem as "nonlinear" or Tolstoy "unhappy families"
