Here’s something I’ll bet you never considered before:
We have a lot of words in common usage, and I mean a LOT of them, a whole specialized vocabulary, that refers to things that don’t actually exist.
So there’s a word for the thing, but no thing for the word.
Fairy. Werewolf. Ghost. Bigfoot. Vampire. Channeling. Telepathy. Telekinesis. Clairvoyance. Goblin. Teleportation. Afterlife. Leprechaun. Zombie. Valhalla. Hell. God.
There are multi-word terms in the same vein: Spirit guide. Trance medium. Guardian angel. Mutant powers.
Knowing this, and knowing that there was a time when I DIDN’T know it, I think that’s a fairly profound problem.
