Why this word is great
ESPIEGLERIE — [Noun] A particular brand of impish or playful mischief, characterized by a light, charming roguishness. Borrowed from French espièglerie, from espiègle ("mischievous, roguish"), itself derived from the German Eulenspiegel ("owl's mirror"), the folkloric trickster Till Eulenspiegel. Unlike "mischief," a broad and often blunt term for troublesome behavior, or "roguery," which implies deceit and self-interest, espièglerie is mischief stripped of malice, distilled to its essence of clever, spirited play. It is the glint in a child's eye before they hide your keys, the deft rearrangement of a bureaucrat's pens into a perfect fan, or the anonymous gift that solves nothing but lightens everything—a minor, conscious rebellion against gravity, where the spirit's lightest touch leaves the deepest imprint.
