This study is making the rounds which refers to a fourth state of matter being present at the core. It seems to me as though euphemisms are being deployed such as "super-ionic" instead of plasma. With that being said, is there a argument for not calling it plasma or is this just another example of semantic side stepping? I appreciate the feedback and thanks for having me here on the forum.

The use of the term "super" in this context is not euphemistic, its use is to indicate the condition of being over the threshold or beyond a point in physical conditions where a physical state (in this case, ionization) must exist.
The the term "super" in "supercritical" is to describe the pressure and temperature above which matter cannot exist as either liquid or solid, like super-heated steam or supercritical nitrous oxide when above 97.5F A supercritical fluid (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist, ...
Other uses of "super" to indicate a physical condition is beyond a threshold are "supersonic" air flow and "supercavitation" flow in water at high speed, as such "supercavitation" describes the velocity above which a cavity in the fluid flow cannot be avoided.
In the context of the article about the earth's core "super" describes the physical conditions as being above or beyond the threshold where matter must exist in the ionic state due to the high temperature.
