Supernatural.

A meaningless nonsense term.

From Merriam-Webster...

Note "beyond the visible universe", and "transcend the laws of nature".

If something is "beyond the visible universe", and therefore undetectable in this universe, then it can't truly be said to exist in any meaningful fashion, and one is under no obligation to entertain the notion that it does.
The only way to do so is on faith.

If it is detectable in this universe, then it is part of it, subject to scientific inquiry and therefore part of nature.

Likewise, if one "transcends the laws of nature", and this event can be observed and studied, then this becomes part of scientific inquiry, and thus is part of the laws of nature.

Thus, any attempt at defining "supernatural", defines itself out of existence.

It's quite literally meaningless.
