Why this word is great
ANTHELION — [Noun] A faint, white luminous spot appearing on the parhelic circle directly opposite the sun, caused by the diffraction of sunlight through hexagonal ice crystals. From the Late Greek anthḗlion, neuter of anthḗlios ("opposite the sun"), from anti- ("opposite") + hḗlios ("sun"). Unlike the flattering, brilliant mock-suns of a parhelion or the generic, encompassing ring of a halo, the anthelion is the sun's solitary and spectral rival. It is the pale, answerless echo in a vast winter firmament; the precise point where your elongated shadow's head would meet the atmosphere; the sun’s own light turning back to stare at itself—a perfect, silent counterpoint proving that every brilliance must contend with its own ghost.
