Look in the mirror. What do you see? A reflection? Nonsense! A reader of Uncommon Parlance observes an enantiomorph: the fancy-pants term for a mirror image. Enantiomorphism also crops up in the field of chemistry where it refers to crystals that are structurally mirror images of each other. Etymology: from Ancient Greek ἐναντίος or enantios (opposite) + μορφή or morphē (form).
