History

Etymology

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). The noun is derived from the adjective.

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).
