Default If Superheterodyne, why not Subheterodyne?

A terminology question I suppose about the derivation of the term
"Superheterodyne" more than anything else:

Does the "Super" actually mean anything? Is there a Subheterodyne?

Traditionally superhets mix a higher radio frequency down to a lower
IF frequency, but certainly in the past few decades radios with IF's
above the RF frequency have become very common in broadband
applications, and those are still called superhets, not subhets :-).


If it comes to that, old Longwave/Mediumwave superhet receivers
generated an IF for the LW band that was higher than the frequency of
the incoming signal. The IF was usually a frequency between the two bands.
