Liminal:
A liminal space is a space between spaces. A liminal space is a boundary between two points in time, space, or both. It’s the middle ground between two grounds, the mid-structure between two structures.
When you’re in a liminal space, you’re neither here nor there, neither this nor that. At the same time, you’re both here and there. Both this and that. [“Liminal space: Definition, examples, and psychology,” Hanan Parvez, PsychMechanics]
Noted in “Do you taboo? On the silence of nonreligion,” Jennifer Michael Hecht, OnlySky:
We’d already won many small battles for the right to disbelieve in peace. But the headline still asked: is the political poison of being an atheist really twenty years stronger than the political bad-beverage of being gay?
My answer is yes. It was. It probably still is. We seem to be in a liminal hinge of history though, where the big problem of voting for an atheist leader might finally go on the decline.
Bank on a poet to come up with that word.
