So we know it is a kind of higher wisdom, meta wisdom, i.e., wisdom in the morontia world.

The etymology of morontia has not been determined, although it has been widely debated among the readers. The Urantia Book clearly defines it:
The book also suggests that "material" could be used in a larger sense, and hence "meta-material" is probably the most concise definition of morontia:
It is used to denote all levels above the physical. By "morontia" they wanted to designate a specific level, between the physical material and the spiritual level. Why they chose that particular word, I have no clue.
A Mighty Messenger says "We incline to the belief that monota is the living, nonspirit energy of Paradise — an eternity counterpart of the living, spirit energy of the Original Son—hence the nonspiritual energy system of the Universal Father."
It is literally non-spiritual mono-dimensional energy.
Supernaphim, seconaphim, tertiaphim, and omniaphim seem to be derivatives of seraphim. Some have argued that seraphim are not angels.
The Urantia Book introduces these ministering spirits with the sentence: "Angels are the ministering-spirit associates of the evolutionary and ascending will creatures of all space." (p. 285, §2) Webster's Third New International Dictionary also defines seraphim as one of the six-winged angels (but we know they do not have wings).
Angel is also a transliteration of the Latin word, angelus, derived from the Hebrew word mal'akh, meaning "messenger."
It should be obvious to any readers that seconaphim is obtained by combining "secon-" in "secondary" and "-aphim" in "seraphim," i.e.,
In any case, tThe Urantia Book repeatedly refers them as "high angels." (p. 287 and 288)
"Spironga" are "spirit helpers" of the local universe (p. 416, §2).
"Spornagia" are an animal order of existence, and they seem to be perfect animals. They
are "landscape gardeners," (p. 527, §6) affording physical ministry to all orders of
universe
personalities requiring material service.
"univitatia" is a residential order of beings, permanent residents of the constellation
worlds. They might be translated as "one-lifers" or "persons with one life," who spend one
life in one place permanently.
For instance, "susatia" are permanent residents of Salvington. Except the fact that they are closely associated with ascendant mortals, there is no clue as to why susatia are named as such.
"abandonter" is a person who is abandont, but are "abandonters" abandoned in the capitals of the superuniverses, or did they abandon their ascendent career there during the present universe age?
