English[edit]

Pronunciation[edit]

A 1778 statue of Pluto, the Greek and Roman god of the underworld, by Dominik Auliczek at the Nymphenburg Palace in Munich, Bavaria, Germany. The word Plutonian means, among other things, “of or relating to Pluto” (etymology 1, adjective sense 1).

Etymology 1[edit]

The adjective is derived from Latin Plūtōnius (of or relating to Pluto, Greek and Roman god of the underworld) +‎ -an (suffix forming adjectives). Plūtōnius is from Ancient Greek Πλουτώνιος (Ploutṓnios, of or relating to Pluto), from Πλούτων (Ploútōn, Pluto) (from πλοῦτος (ploûtos, riches, wealth) (ultimately from Proto-Indo-European *plew- (to fly; to flow; to run)) + -ων (-ōn)) + -ιος (-ios, suffix forming adjectives). The English word is cognate with Middle French plutonien (modern French plutonien).[1] The noun is derived from the adjective.

      One system, now called the Plutonian, regards, the earth's crust on which we now live, as the debris of two former worlds, and our present continents as the elevations of the bottom of the sea by subterranean heat. If this theory be founded on fact, why do not our rocks present us with beds of shell-fish in families as are now living at the bottom of the sea?

      The country around Aberdeen is almost entirely composed of primitive rocks. Of these there are two sets, Neptunian and Plutonian. [...] [T]he Plutonian rocks are granite, with feldspar, or granitic porphyry. [...] [T]he great bodies of Plutonian granite, as those exposed in the celebrated granite quarries, render it probable that the stratified Neptunian rocks owe much of their contorted and broken aspect, and also, in some degree, their position, to the action of this igneous rock.

Etymology 2[edit]

A composite image of the dwarf planet Pluto taken on 14 July 2015 by the US National Aeronautics and Space Administration’s space probe New Horizons. The word Plutonian can mean “of or relating to Pluto”, and “an (imaginary) inhabitant of Pluto” (etymology 2, adjective sense 2 and noun sense 2).

From Pluto (dwarf planet in the Solar System) +‎ -n- +‎ -ian (suffix forming adjectives meaning ‘from, related to, or like’, or nouns meaning ‘one belonging to, relating to, or like’), probably influenced by Plutonian (of or relating to Pluto, Greek and Roman god of the underworld) (see etymology 1).

      Another and perhaps more Plutonian view of this would be that David's bondage to his mother and the codes of behaviour which she set for him had extended throughout his life, in both profes[s]ional and personal spheres; and that bondage now had an opportunity of loosening, with all the attendant consequences.

      Burl studied the captured Plutonian hand weapons, and was pleased to have one of the Neptunian soldiers pick one up and demonstrate how it was fired.

      Roure did not carry his work to completion.

      [Gerard] Kuiper (1944) searched for spectroscopic evidence of an atmosphere around Pluto as part of the same program that discovered CH4 on Titan. Because of the difficulty of observing an object as faint as Pluto, no useful results were obtained; however, Kuiper presented arguments in favor of a Plutonian atmosphere based on the stability of the atmosphere against loss to space.

      If you are a Plutonian and some of these traits emphatically do not fit you, just let them go and take what is helpful and descriptive of you personally. What will be given is a composite picture, based on working with a great many Plutonians over the years. Plutonians who are negatively inclined are often very guarded and rigid, afraid to let others get close.
