ineffable : (adj) too great or extreme to expressed in words
“I mean, maybe you just want to see how it all turns out. Maybe it’s all part of a great big ineffable plan. All of it. You, me, him, everything. Some great big test to see if what you’ve built all works properly, eh? You start thinking: it can’t be a great cosmic game of chess, it has to be just very complicated Solitaire.”
-Good Omens
I need to reread Good Omens. It’s been too long.
