[Projoy] Words? NO. [Rosie] Medical connection? NO.

[Rosie] Casting out devils? NO.

I suspect that I have put people on the wrong track, so if anyone would like a hint, let me know.

Far too early for a hint, yet.

[Darren] Ceremonial? NO.
[Irouléguy] From an Asian culture? NO.

[Rosie] Inscription? Sometimes, though not so often in the modern day.

[Darren] To do with death? NO.
[ImNotJohn] An obituary? NO.
[Rosie] An epitaph? NO.

[Quendalon] Rather than a hint - please can you do a summary. It may help us realign ourselves :-)

[Irouléguy] To do with war or the military? NO.
[Chalky] Skepticism? NO.

And now to summarize! I’ll also correct a couple of my own answers where I think I may have misread or misinterpreted your questions. So:

This abstract is a human construct. It was once specific to a particular culture, though not an Asian culture. It has to do with language, but it is not a particular form of words.

It is not an emotion, a philosophy, a type of comedy, an action, an epitaph or obituary, or Feng Shui.

It is not inherently connected to science, to swearing, to sex, to religion, to the worship of some unusual object or event, to medicine, to casting out devils, to death, to war or the military, or to skepticism.

Notably, the subject has experienced a shift in use over time. Originally, it had a connection with positive emotion, was often inscribed (in the sense of being etched into a solid surface), and was sometimes connected with magic. These all still apply when the subject is put to its original use. In its modern use, it has no connection with positive emotion or magic, and is still inscribed in the sense of being written down, though rarely (if ever) in the sense of being etched into a solid surface.
