What am I missing?* Are they actually talking about the casing?* The
casing is not wire...

I believe the Non-Metallic (NM) means the sheathing is made of plastic,
not metal.
There are times when it's required to have metal-sheathed wire and times
when you can use Romex, non-metallic sheathed wire.

So that's the designation.* MC for metal clad, and NM for non-metallic.



Understood but it specifically says non metallic "wire". And I do not
ever recall Romex ever being called metallic or non metallic.


It's not uncommon, assuming that you accept that by referring to something
by using the initials NM, it is being referred to as non-metallic.

"Romex® is the specific brand name for a non-metallic (NM) building wire
made by Southwire. In other words, Romex® is technically just one brand
of NM cable. However, the term Romex is often used generically (though
inaccurately) to describe any type of NM cable, no matter which manufacturer
made it."
"Romex" is not wire - it is CABLE. A "wire" is a single conductor
