I find I do this sort of thing a surprising amount. You'd think spurious symbols would jump out at you, but actually it turns out that's not how it is. Luckily oulipo.social automatically stops you posting bad sigils.
But you still don't instill that actual individual in minds, and an actual, non-abstract, particular individual is occasionally crucial to a thought. Without that word you would basically go back to that activity in which pairs of folks try to find out a thing without using words. This is a bit of an auto-proof as I can't say its word.
It's not as if you can simply work around and pick similar words for that individual's particular noun, you miss almost all of a thought by dancing around it vs. using a fast shortcut that quickly aligns thoughts with low odds of ambiguity.
