I’m annoyed by almost all claims of the form “X is indescribable by words.” These people rarely distinguish “this is very difficult to describe with words” from “this is literally impossible to describe with words.” Very often these people just aren’t trying hard enough.
I don’t deny that some things are literally indescribable with language, for example, “What redness feels like from my point of view.” However, most things aren’t like this. Very often this tactic is used to make the thing you are talking about seem more deep than it really is. OoOoO language can’t describe it. It is mystical and profound. Stop.
