Why this word is great
TARTAREAN — [Adjective] Of, relating to, or resembling Tartarus, the infernal abyss of Greek mythology; hence, infernal or hellish. From the Latin Tartareus ("of Tartarus"), from Greek Tartareios ("of Tartarus"), combined with the English adjectival suffix -an. Unlike "chthonic," which broadly denotes underworld spirits of the earth, or "stygian," which poetically emphasizes a profound darkness, Tartarean specifies the punitive, abyssal, and irrevocably hellish nature of that specific mythological pit. It is the sulfurous breath from a fissure in a barren field, the iron chill of a sunken oubliette, and the absolute silence that follows the last echo of a fallen scream—the quality of a despair that is not fiery torment, but the profound, geological chill of eternal exclusion.
